COMMERCIAL FERTILIZERS. 
 
 By GEORGE ROBERTS. 
 
 At the session of 1903 the State Legislature passed the following act 
 to regulate the sale of commercial fertilizers: 
 
 •CHAPTER CCXXV. — An act to regulate the sale of commercial fertilizers or materials 
 used for manurial purposes, and to provide penalties for the infraction thereof, and means 
 for the enforcement of the act. 
 
 [Approved March 20, 1903.] 
 
 The People of the State of California, represented in Senate and Assembly, do enact as 
 
 follows: 
 
 Section 1. Every lot, parcel, or package of commercial fertilizers or materials to be 
 used for manurial purposes (excepting the dung of domestic animals), sold, offered, or 
 exposed for sale, within this State, shall be accompanied by a plainly printed label, 
 stating the name, brand, and trade mark, if any there be, under which the fertilizer is 
 sold, the name and address of the manufacturer, importer, or dealer, the place of manu- 
 facture, and a chemical analysis, stating the percentages claimed to be therein ; of 
 nitrogen, specifying the form or forms in which it is present; of phosphoric acid, avail- 
 able and insoluble ; and of potash, soluble in distilled water, and the materials from 
 which all of said constituents are derived. All analyses are to be made according to 
 the methods agreed upon by the American Association of Official Agricultural Chemists. 
 In the case of those fertilizers, the selling price of which is less than eight dollars ($8) 
 per ton, said label need only give a correct general statement of the nature and com- 
 position of the fertilizer it accompanies. 
 
 Sec. 2. No person shall sell, offer, or expose for sale in this State, any pulverized 
 leather, hair, ground hoofs, horns, or wool waste, raw, steamed, roasted, or in any 
 form as a fertilizer, or as an ingredient of a fertilizer or manure, without an explicit 
 statement of the fact; said statement to be conspicuously affixed to every package of 
 such fertilizer or manure, and to accompany and go with every lot, parcel, or package 
 of the same. 
 
 Sec 3. The manufacturer, importer, agent of, or dealer in any commercial fertilizers, 
 or materials used for manurial purposes, the selling price of which to the consumer is 
 eight ($8) dollars or more per ton, shall, before the same is offered for sale, obtain a cer- 
 tificate of registration from the Secretary of the Board of Regents of the University of 
 California, countersigned by the Director of the Agricultural Experiment Station of the 
 said University, authorizing the sale of fertilizers in this State, and shall securely fix to 
 each lot, parcel or package of fertilizer the word " registered " with the number of reg- 
 istry. The manufacturer, importer, agent, or dealer, obtaining such registry, shall pay 
 to the said Secretary the sum of fifty ($50) dollars, to be applied as provided in section 
 nine of this act; such registration shall expire on the thirtieth day of June of the fiscal 
 year for which it was given ; provided, the provisions of this section shall not apply to 
 any agent whose principals shall have obtained a certificate of registration as herein 
 
4 UNIVERSITY OF CALIFORNIA — EXPERIMENT STATION. 
 
 provided. Every such manufacturer, importer, agent, or dealer, who makes or sells, or 
 offers for sale, any such substances, under a name or brand, shall file, on or before the 
 first day of July, in each year, a statement, under oath, with said Director, stating such 
 name or brand, and stating the component parts in accordance with the provisions of 
 section one of this act, of the substances to be sold, or offered for sale, or manufactured 
 under each such name or brand. 
 
 Sec. 4. The said Director shall annually, on or before the first day of September, 
 take samples in accordance with the provisions of section five hereof of the substance 
 made, sold, or offered for sale, under every such name or brand, and cause analyses to 
 be made thereof in accordance with the provisions of section one hereof, and said 
 analyses may include such other determinations as said Director may at any time deem 
 advisable. Dealers in, or manufacturers of fertilizers, must give free access to the 
 Director of the Agricultural Experiment Station, or his duly authorized deputy, to all 
 the materials which they may place on the market for sale in California. Whenever 
 the analysis certified by the said Director shall show a deficiency of not more than one 
 fourth of one per cent of nitrogen, or one per cent of soluble or available phosphoric 
 acid, or one half of one per cent of potash soluble in distilled water, the statement of the 
 manufacturer or importer, as required in section one of this act, shall not be deemed to 
 be false in the meaning of this act; provided, that this act shall not apply to sales of fer- 
 tilizing materials made to a registered manufacturer of fertilizers, or to sales for export 
 outside of this State ; provided further, that the said Director of the Agricultural Experi- 
 ment Station of the University of California shall, upon the receipt of a sample of fer- 
 tilizer, accompanied with a nominal fee of two ($2) dollars, furnish to the user of said 
 commercial fertilizer, such examination or analysis of the sample as will substantially 
 establish the conformity or non-conformity of the said fertilizer to the guarantee under 
 which it was sold. 
 
 Sec. 5. The Director of the Agricultural Experiment Station of the University of Cali- 
 fornia, in person or by deputy, is hereby authorized to take a sample not exceeding two 
 pounds in weight for analysis by the said Director, or his deputies, from any lot, parcel, 
 or package of fertilizer, or material, or mixture of materials used for manurial purposes, 
 which may be in the possession of any manufacturer, importer, agent, or dealer, but 
 said sample shall be drawn in the presence of said party or parties in interest, or their 
 representatives. In lots of five tons or less, samples shall be drawn from at least ten 
 packages, or, if less than ten packages are present, all shall be sampled; in lots of 
 over five tons, not less than twenty packages shall be sampled. The samples so 
 drawn shall be thoroughly mixed, and from it two equal samples shall be drawn and 
 placed in glass vessels, carefully sealed, and a label placed on each, stating the name or 
 brand of the fertilizer or material sampled, the name of the party from whose stock the 
 sample was drawn, and the time and place of drawing; and said label shall also be 
 signed by the said Director or his deputy making such inspection, and by the party or 
 parties in interest, or their representatives present at the drawing and sealing of said 
 samples. One of said duplicate samples shall be retained by the party whose stock was 
 sampled, and the other by the Director of the Agricultural Experiment Station of the 
 University of California. 
 
 Sec 6. The Director of the Agricultural Experiment Station of the University of 
 California shall publish in bulletin form, from time to time, at least annually, the 
 results of the analysis hereinbefore provided, with such additional information as cir- 
 cumstances may advise. 
 
 Sec. 7. There is hereby appropriated for the use of the Agricultural Experiment 
 Station of the University of California at Berkeley, Alameda County, as set forth in 
 this act, out of any moneys in the treasury not otherwise appropriated, the sum of 
 eighteen hundred ($1,800) dollars for the equipment of a laboratory, with the chemicals 
 and apparatus, and other incidentals necessary to the successful prosecution of the work. 
 
 Sec. 8. In order to further provide for the necessary expenses of this work, there 
 shall be paid by the manufacturer, importer, agent, or dealer, twenty-five cents for every 
 ton of fertilizer sold, the selling price of which to the consumer is eight ($8) dollars or 
 more per ton. A statement sworn to by the manufacturer, importer, agent, or dealer, 
 of such sales, shall be rendered quarterly to the Secretary of the Board of Regents of 
 
COMMERCIAL FERTILIZERS. 5 
 
 the University of California, accompanied by the corresponding amount of the special 
 license fee as above specified ; provided, that whenever the manufacturer or importer 
 shall have paid the special license fee herein required, for any person acting as agent 
 or seller for such manufacturer or importer, such agent or seller shall not be required to 
 pay the special license fee named in this section. On receipt of said special license fee 
 and statement, the said Secretary shall issue to the manufacturer, importer, agent, or 
 dealer, a certificate of compliance with this section. 
 
 Sec 9. All moneys, whether received from registry and analytical fees or special 
 license fees, shall be paid to the Secretary of the Board of Regents of the University of 
 California, for the use of said board in carrying out the provisions of this act. 
 
 Sec. 10. Any party selling, offering, or exposing for sale, any commercial fertilizer 
 without the statement required by section one of this act, or with a label stating that 
 said fertilizer contains a larger percentage of any one or more of the constituents men- 
 tioned in said section than is actually contained therein, except as provided for in 
 section four, or respecting the sale of which all the provisions of this act have not been 
 fully complied with, shall be deemed guilty of a misdemeanor, and upon conviction 
 thereof before any court of competent jurisdiction, shall be fined in a sum not less than 
 fifty ($50) dollars and costs of action for the first offense, and one hundred ($100) dollars 
 and costs of the action for each subsequent offense. Said fines to be paid into the 
 school fund of the county in which conviction is had. 
 
 Sec. 11. In any action, civil or criminal, in any court in this State, a certificate 
 under the hand of said Director, and the seal of said University, stating the results of 
 any analysis, purporting to have been made under the provisions of this act, shall be 
 prima facie evidence of the fact that the sample or samples mentioned in said analysis 
 or certificate were properly analyzed as in this act provided ; that such samples were 
 taken as in this act provided ; that the substances analyzed contained the component 
 parts stated in such certificate and analysis ; and that the samples were taken from the 
 parcels or packages or lots mentioned or described in said certificate. 
 
 Sec 12. This act shall take effect and be in force from and after July first, nineteen 
 hundred and three.

 As required by Section 4 of the law, an inspection was made before 
 September 1st (in August), which resulted in the collection of 70 sam- 
 ples. Eleven of these samples were not analyzed, some being materials 
 to which the law did not apply, and others having been taken from old 
 goods which the manufacturers agreed to ship back to the factory. 
 
 About three fourths of these samples were taken from remnants of 
 goods that were put on the market before the law went into effect, and 
 it was not thought worth while to issue a separate bulletin giving the 
 analyses of these samples; but they are included in this report for 
 comparison with goods that were put on the market after the law went 
 into effect. 
 
 Another inspection, covering nearly the whole of the State, was made 
 during the latter part of December and in January and February. 
 This inspection resulted in the collection of 47 samples. Two of these 
 samples were not analyzed, one being an unnecessary duplicate, and 
 one a sample taken from only one bag, and hence not considered a 
 fair sample. The small number of samples found on these two in- 
 spections is due to small sales of fertilizers caused by the prolonged 
 drought in the southern part of the State, and to the poor prices of 
 oranges. 
 
 In addition to the samples collected by the inspectors, 13 samples of 
 registered materials were sent in by farmers. The total number of 
 analyses of registered materials was 117, representing 82 brands and 
 special formulas. 
 
 Three samples of miscellaneous fertilizing materials, not covered by 
 the law, were analyzed, and these results are also reported. 
 
 ANALYSES FOR CONSUMERS. 
 
 Any user of fertilizers may, by paying the fee specified by Section 4 
 of the fertilizer law, have a sample of his material analyzed. This fee 
 does not begin to pay the cost of the analysis, but the nominal charge 
 is made to prevent the sending of samples through idle curiosity, as is 
 always the case when analyses are made free of charge. 
 
 The sample should be drawn from the amount of fertilizer, and in 
 the manner prescribed by Section 5 of the law, and whenever possible 
 it should be drawn in the presence of the agent, who should sign, as a 
 witness, the certificate given below. If the sample is not drawn in the 
 presence of the agent, it should be done in the presence of some other 
 person, who should sign the certificate as a witness. Special care should 
 be exercised to thoroughly mix the large sample before drawing the 
 small sample to send to the Station. This is absolutely necessary to 
 obtain a trustworthy result. A sample filling a quart fruit jar is about 
 the proper amount to send. Consumers' samples will be given prefer-

 ence and the results reported as soon as possible. The sample should 
 be sent in time to receive the report before the fertilizer is used, or else 
 the bags from which the sample is taken should be reserved until the 
 report is received, so that in case of controversy with the manufacturer 
 an official sample may be drawn. 
 
 The form of certificate given below should be used in sending a sam- 
 ple for analysis. Blank forms will be furnished upon application. 
 When more than one sample is sent, they should be marked in some 
 way so that they may be identified. The samples should be sent pre- 
 paid, addressed to the Fertilizer Control, Experiment Station, Berkeley, 
 and should bear the name and address of the sender. Bank checks and 
 money orders should be made payable to "The Regents of the Uni- 
 versity of California." Letters, certificates and remittances should not 
 be enclosed with the samples, but mailed separately. When the report 
 is received, a tag or label taken from one of the bags sampled should 
 at once be sent and the name and address of the agent from whom the 
 goods were purchased should be given. Analyses will be made only for 
 those who purchase fertilizers for their own use.

 This is to certify that I am not a dealer in, or agent for the sale of 
 any fertilizer, and that the fertilizer, a sample of which I have sent you 
 
 for analysis, was purchased by me , 190. _ , for my own use 
 
 and not for sale. 
 
 I further certify that the amount purchased was tons, and 
 
 that the sample was drawn from packages and was thoroughly 
 
 mixed. 
 
 Upon receipt of the analysis from you, I agree to furnish you with a 
 tag or label taken from one of the packages sampled, and the name and 
 address of the firm or agent of whom the fertilizer was purchased. I 
 enclose two dollars analysis fee.

 EXPLANATION OF TERMS. 
 
 Phosphoric Acid. — The phosphoric acid used in fertilizers comes 
 almost wholly from bone and phosphate rock. In bone the phosphoric 
 acid is in combination with three parts* of lime, and it is chiefly in 
 this form in phosphate rock. In most cases the bone and phosphate 
 rock used have been acidulated (by means of sulfuric acid), giving rise to 
 the product called superphosphate. The phosphoric acid in this product 
 is found in three forms, namely, mono-calcium phosphate, in which the 
 phosphoric acid is in combination with one part of lime; di-calcium 
 phosphate (the so-called reverted phosphoric acid), in which the 
 phosphoric acid is in combination with two parts of lime; and finally, a 
 small percentage of the original material not affected by acidulation 
 remains in the form of tri-calcium phosphate. Mono-calcium phosphate 
 is soluble in water, and the di-calcium phosphate is soluble in a neutral 
 solution of ammonium citrate. These forms are rated as available 
 phosphoric acid. But the term " available " is not limited to these forms. 
 It signifies all phosphates soluble in water and ammonium citrate. 
 Raw bone is to some extent soluble in ammonium citrate, and steamed 
 bone more so. The more finely the bone is ground the greater its solu- 
 bility. In a mixed fertilizer, such a part of the insoluble phosphoric 
 acid as is from bone is as valuable as if it were in bone meal of the same 
 degree of fineness. 
 
 Any soluble phosphates that are applied to the soil become, in a 
 short time, insoluble again by combining with lime and other elements 
 of the soil. The question arises then, What is the use of applying 
 soluble phosphates in the first place? When soluble phosphates are 
 applied, they are carried in solution and evenly distributed in the soil 
 and fixed in very minute particles. The availability of phosphates 
 depends to a large extent upon their fineness. If bone and phosphate 
 rock could be reduced to particles as minute as those that result from 
 the fixation of soluble phosphates, and if this fine powder could be as 
 evenly distributed, then it would perhaps not be worth while to render 
 phosphates soluble. 
 
 Phosphoric acid in bonef meal becomes slowly available in the 
 process of decay of the bone. As has already been suggested, steamed 
 bone is more available than raw bone, and the degree of availability is 
 influenced by the fineness of the bone. 
 
 Thomas Phosphate Powderf is another form of phosphate used to a 
 considerable extent in this State. It is a by-product of the Bessemer 
 process of refining steel, and is peculiar in that the phosphoric acid is in 
 
 *Chemical molecules. 
 
 fAvailable phosphoric acid is not determined in bone, tankage, and Thomas Phos- 
 phate Powder, but the degree of fineness of these materials is determined, as indicated 
 further on.

 combination with four parts of lime. There is also some caustic lime 
 in the material. It usually contains from 16 to 20 per cent of phos- 
 phoric acid. Its availability is a somewhat mooted question in this 
 State, although it is no longer a question in Europe, where tens of 
 thousands of tons are used annually. It possesses the advantage that 
 it can be reduced to a very fine powder. The proper way to settle the 
 question of its availability is for each farmer to test it on his particular 
 soil by comparing its effect with that of a superphosphate containing 
 the same amount of phosphoric acid. The results produced and the 
 cost of the materials should settle the matter. 
 
 The percentage of phosphoric acid expressed in fertilizer analysis 
 signifies the amount of phosphorus pentoxid (P2O5) present. 
 
 Potash. — The percentage of potash, as used in fertilizer analysis, des- 
 ignates the equivalent of potassium oxid (K 2 0) present. It is some- 
 times called " actual potash." Potash is not present in fertilizers as 
 such, but almost wholly as the salts potassium sulfate and potassium 
 chlorid ("muriate of potash"). In wood ashes it is in the form of 
 potassium carbonate. Potash (K 2 0) may be considered to exist in the 
 sulfate (K2SO4) and in the carbonate (K 2 C0 3 ), but not in the chlorid 
 (KC1). All these salts are soluble in water and equally available, but 
 when applied to the soil, the potash becomes fixed. Potassium chlorid 
 is not considered as valuable as the sulfate or carbonate, for the reason 
 that chlorin is injurious to some crops. The fixation of the potash 
 liberates the chlorin, which in turn unites with elements of the soil and 
 again forms soluble chlorids (of calcium and magnesium). Thus the 
 chlorin is still in a form injurious to plants. When chlorin is present 
 in other materials used in the fertilizer, its effect is the same; so it 
 becomes quite necessary for the manufacturer to select materials as free 
 as possible from chlorin. 
 
 But in this State there is another reason for guarding against the use 
 of fertilizers containing an appreciable amount of chlorin, and that is 
 that the soil is frequently heavily charged with alkali salts, about half 
 of which are chlorids, and nowhere contains less than about ten times 
 as much as soils in the East. 
 
 In the report of analyses, the percentage of chlorin is given when it 
 exceeds 0.50 per cent; and when there is an amount present sufficient 
 to combine with half or more of the potash, the potash is rated as 
 derived from potassium chlorid (muriate) to the extent of the combin- 
 ing equivalent of the chlorin, whether it is in actual combination or 
 not. This allowance is really too liberal, and may seem to open the 
 way for the dishonest manufacturer to mix muriate with his sulfate; 
 but it is assumed that the manufacturers are honest, and that when 
 sulfate is claimed, sulfate has been used, and that any chlorin present

 is from some other materials used. The microscope will, however, show 
 whether or not fraud was attempted. Goods may be made practically 
 free from chlorin, as will be seen by referring to the table of analyses. 
 
 Nitrogen. — Nitrogen is by far the most expensive ingredient in a fer- 
 tilizer, and the most difficult to use properly. Phosphoric acid and 
 potash become fixed in the soil, but this is not always so with nitrogen. 
 There is always the danger of loss by leaching whenever nitrates are 
 present. Unlike nitrates, ammonia is quite tenaciously retained by 
 soils, very much as is potash, but gradually nitrifies, and then of course 
 becomes subject to leaching out. 
 
 Nitrogen occurs in fertilizers in three forms, namely, in nitrates, in 
 ammonia salts, and as organic nitrogen. Nitric nitrogen is derived 
 almost exclusively from nitrate of soda (Chile saltpeter). This salt is 
 soluble in water, and is at once available. Ammonium sulfate is the 
 chief source of nitrogen in ammonia salts. This is also soluble in 
 water, but not quite so widely available as nitrate of soda. It is not 
 extensively used at present, on account of its high price. Some fertil- 
 izers contain a small percentage of nitrates and ammonia salts pro- 
 duced by conversion of organic nitrogen. Guanos contain both nitrates 
 and ammonia salts produced in this way. 
 
 Organic nitrogen is found in almost every form of animal and plant 
 growth, and varying in availability from that found in meat and blood, 
 for example, to that found in leather, which is practically worthless. 
 The chief sources of organic nitrogen in fertilizers are dried blood, 
 tankage, bone, and fish scrap. Hair, hide, wool waste, leather, hoof, 
 and horn are rich in nitrogen, but of low availability, and their use in 
 fertilizers is forbidden by law, except with the explicit statement of the 
 fact attached to every bag containing such materials. 
 
 Since nitrogen is such an expensive ingredient, and since California 
 soils are so generally deficient in it, the greatest care and judgment 
 should be used in the purchase of fertilizers containing it. The farmer 
 should not only know how much nitrogen is present, and the materials 
 from which it is derived, but he should know how much is present 
 in each form, that is, how much each of nitric, ammoniacal, and 
 organic nitrogen. If, for example, a fertilizer containing a large per- 
 centage of nitrogen in nitrate of soda should be applied to a sandy 
 soil just before the rainy season begins, the nitrogen would be lost by 
 leaching before the plant could use much of it. On the other hand, a 
 fertilizer may be desired containing the nitrogen in this form in order 
 to produce a quick growth in certain crops. Again, a fertilizer may be 
 desired with just enough sodium nitrate in it to give the crop a start, 
 and with the remainder of the nitrogen in organic or ammoniacal form 
 which will become gradually available through a longer period of time. 
 All these conditions make it necessary that the farmer know what he

 is purchasing, and the farmer should require an explicit statement of 
 the amount of each form in the fertilizer. 
 
 VALUATION OF FERTILIZERS. 
 
 The "agricultural value " and the "commercial value" of fertilizing 
 materials are not synonymous terms. The agricultural value of a fer- 
 tilizer is measured by the value of the increase in crop produced by its 
 use. Nitrate of soda, one of the cheapest forms of nitrogen, produces 
 on many crops, under proper conditions, a more profitable increase than 
 the slower-acting forms; while on other crops, slower-acting and more 
 expensive forms produce a more profitable increase. The commercial 
 value is, of course, to some extent regulated by the agricultural value. 
 
 In calculating the values given in this report, the Station does not 
 undertake to say what the retail prices of fertilizers should be in this 
 State. The schedule of values used was adopted November 1, 1903, and 
 represents, as nearly as could be determined at the time, the retail 
 values, at centers of distribution like San Francisco, of phosphoric acid, 
 nitrogen, and potash in raw materials of good quality. The values 
 given for mixed goods do not take into account the cost of grinding, 
 mixing, drayage, insurance, agent's commission, and other expenses of 
 the manufacturer. 
 
 The following is the schedule of values used for calculating the 
 values given in this report :

 * Fine and medium bone are separated by a sieve with 50 meshes to the inch; fine 
 and medium tankage by a 25-mesh sieve; and fine and medium Thomas Phosphate 
 Powder by a 100-mesh sieve. 
 
 t These values and this separation are temporary, awaiting the adoption of methods 
 by the Association of Official Agricultural Chemists. The values are based upon 
 European practice. 
 
COMMERCIAL FERTILIZERS. 15 
 
 Organic nitrogen in guanos is given a value depending upon the 
 quality of the guano. For example, a bird or bat guano containing an 
 abundance of feathers or insect wings would be given a low valuation 
 upon its organic nitrogen. 
 
 To calculate the value of a fertilizer, multiply the value per pound 
 of an ingredient by the percentage of the ingredient present, then mul- 
 tiply this result by 20. The sum of the results for all the ingredients 
 is the value per ton. The term "unit" often used by fertilizer dealers 
 signifies 20 pounds of an ingredient, or 1 per cent on the ton. 
 
 REPORT OF ANALYSES. 
 
 The following table gives the results of all analyses made to date. 
 The star (*■) before a sample indicates that it was taken from goods 
 that were on the market before the law went into effect, "f" indicates 
 that the sample was sent by a farmer. No goods were found to contain 
 materials different from those claimed, except as indicated in the table. 
 
 The following abbreviations are used to designate materials used : 
 Nit. = nitrate of soda; Bl. = blood; Bn. = bone; Am. Sul. == am- 
 monium sulfate; Bat G. = bat guano; Bd. G. == bird guano; Fs. G. = 
 fish guano*; T. = tankage. 
 
 Only those samples were analzyed for ammonia-nitrogen in which 
 this form of nitrogen was guaranteed, or in which some material was 
 used which was known to contain ammonia salts. Several tests were 
 made on mixed fertilizers other than those mentioned, and the results 
 obtained did not justify the time and labor required to make the tests. 
 However, if any samples on which this test was not made, contained 
 any ammonia-nitrogen, it will be included in the nitrate-nitrogen, and 
 it has practically the same agricultural value. Hereafter, however, all 
 samples will be analyzed for ammonia-nitrogen.

 a compensating excess in the other ingredient or ingredients, which 
 made the value on the analysis equal to or greater than the value on 
 the guarantee. This does not indicate any dishonesty on the part of 
 the manufacturer, but indicates poor mixing. It is gratifying to note 
 that, as a class, the manufacturers doing business in the State are meet- 
 ing their guarantees, and to all such the fertilizer law is a protection. 
 
 REPORT OF SALES. 
 
 The reports of sales required by Section 8 of the law showed the fol- 
 lowing for the first two quarters of the fiscal year: 
 
 Quarter ending September 30, 1903 1,404 tons. 
 
 Quarter ending December 31, 1903 1,451 tons. 
 
 The reports for the third quarter are not all in as this report goes to 
 press, but the indications are that the sales will be approximately 4,000 
 tons. 
 
 As has already been suggested, the fertilizer dealers give two reasons 
 for these small sales, namely, the prolonged drought in southern Cali- 
 fornia, and the poor prices received for the orange crop.

 ECONOMY IN THE USE OF HIGH-GKADE FERTILIZERS. 
 
 Farmers are advised to use fertilizers containing a high percentage 
 of ingredients, for the reason that they are cheaper. A comparison of 
 the following formulas will show why this is true. Suppose, for exam- 
 ple, a fertilizer of this low-grade composition is offered: 
 
 Phosphoric acid 6% = 600 lbs. 20% superphosphate. 
 
 Nitrogen 2% = 275 lbs. blood and nitrate of soda. 
 
 Potash 3% = 125 lbs. sulfate of potash. 
 
 Total materials used 1,000 lbs. 
 
 Filler required to make out the ton_ 1,000 lbs. 
 
 Another of this higher-grade composition is offered : 
 
 Phosphoric acid 12% = 1,200 lbs. 20% superphosphate. 
 
 Nitrogen 4% = 550 lbs. blood and nitrate of soda. 
 
 Potash 6% = 250 lbs. sulfate of potash. 
 
 Total materials used 2,000 lbs. 
 
 No filler required. 
 
 Supposing the second formula to cost twice as much as the first, 
 money will be saved by buying the second ; because, for the same amount 
 of plant-food, only one half of the second would be needed per acre, 
 and this would require but one half of the freight charges and one 
 half the time spent in handling. Nor is this all. The filler is worth- 
 less to the farmer, but it costs the fertilizer manufacturer as much 
 to mix and handle the filler as it does the fertilizing materials them- 
 selves, and he charges for the expense. Farmers have been heard to 
 exclaim in surprise and disgust that they have seen fertilizers that 
 actually contained sawdust, cinders, sand, etc. No doubt they have. 
 The manufacturer is at liberty to use anything for a filler he chooses, 
 so long as it is not an injurious material. The farmer himself is 
 responsible for low-grade goods. He demands a fertilizer at a low price 
 per ton, and the filler is absolutely necessary, but he is paying a very 
 high price for the actual plant-food contained. If the farmer wants 
 high-grade goods the manufacturers will gladly make them. 
 
 THE NEW FERTILIZER LAW. 
 
 The California fertilizer law is fully abreast of the times in its pro- 
 visions. Its distinguishing feature is the requirement that the sources 
 of the ingredients be stated on the labels. The wonder is that all State 
 laws have not required this, but as a matter of fact only a few have 
 done so. But this feature is more important in California than in any 
 other State having a fertilizer law. As was suggested in the discussion 
 of nitrogen, the nature of the climate and soil here make it highly 
 accessary that the farmer know just what materials he is using. The 
 Fertilizer Control is endeavoring to require the manufacturer to state 
 
COMMERCIAL FERTILIZERS. 21) 
 
 not only the total percentage of nitrogen and the materials from which 
 it is derived, but also the amount present each of- nitric, ammoniacal, 
 and organic nitrogen. The law clearly warrants this construction, and 
 it is what was speciallyantended by its framers. Whether or not the 
 Fertilizer Control is successful in carrying out the requirement, the 
 consumers of fertilizers should demand this knowledge. Opposition to the 
 requirement has come from only a very limited riumber of manufacturers, 
 and the chief objection urged is that it would require the manufacturer 
 to give away his secrets. This is not true, however. It is only required 
 that the manufacturer give the information on the manufactured goods, 
 and does not require him to state a single fact as to the process of manu- 
 facture. 
 
 The statement has been made that the farmer does not care to know 
 of what materials his goods are made, and that he, as a rule, wants 
 to leave the matter of selecting fertilizers for his crops to the manu- 
 facturer. There may be a few farmers so averse to thinking for 
 themselves that they want to do this, but it is to be hoped that at least 
 ninety-nine per cent of the farmers in California are progressive enough 
 to want to know why they use this or that formula; and to know this, 
 requires that they shall know the full composition of the fertilizer, 
 and what part each component in the fertilizer plays. It would be a 
 hopeless state of affairs if our farmers were willing to commit them- 
 selves to that practice, no matter how honest the manufacturers may 
 be, and settle down into a state of "blissful ignorance." Such a placid 
 resignation of the exercise of judgment on the part of the farmers 
 would preclude the necessity for a fertilizer law, and the principle 
 carried to its logical conclusion would also render nugatory many of 
 the other efforts of the Agricultural College and the Experiment Station 
 to familiarize farmers with the principles of rational agriculture. 
 
 The Station has not the slightest desire to array the farmer against 
 the manufacturer. It is its purpose to see that both sides get fair treat- 
 ment, and it will always stand on this ground. There should be confi- 
 dence between the two, but it should be a confidence born of intelligence, 
 and not of blind faith. 
 
 THE LABELING OF FERTILIZER PACKAGES. 
 
 To be properly labeled each bag or package of fertilizer should bear 
 the following information, which may be upon a tag attached to the 
 bag or it may be printed on the bag, provided it is plainly done: 
 
 The name and address of the manufacturer, and place of manufacture. 
 
 The name or brand of fertilizer. 
 
 "Registered" No 
 
 A chemical analysis, giving the percentages of essential ingredients. 
 
 A statement of the materials from which the essential ingredients are 
 derived.
