The California State Fertilizer Control attempts to prevent the adulteration of fertilizers by a systematic inspection and examination of fertilizers found on the open market and in the hands of purchasers. The tabulated results of these examinations, together with the manu- facturers' guaranties, are published semi-annually for the information of prospective purchasers and others interested in the sale of commer- cial fertilizers. These publications, by showing the brands that conform to or fall below the guaranties of their manufacturers, indicate which manufacturers' guaranties are the more reliable. It is considered that this has the effect of causing discrimination, on the part of purchasers, against the unreliable goods; and by diminishing sales serves as a constant inducement to the trade to put out goods conforming to guaranties. The purpose of the State law and the object of the Control is primarily to prevent fraud in a commodity which is peculiarly subject to adulteration. It is not designed to pick out the so-called "best fertilizer, ' ' as some correspondents seem to think. There is no one class of fertilizers that will give maximum returns in growth and crop for the least money under all possible circumstances. All the classes of goods reported in these bulletins are believed to have a certain value, when applied to soils to which they are adapted and under conditions suited to them. So that under varying circumstances each class may be the ideal "best fertilizer." While certain well-known principles frequently alluded to in the publications of this Department may serve as guides in deciding which is the best class of fertilizers for a given soil and crop, the final choice must always depend on a knowledge of local conditions and past experience with fertilizers on the soil and crop under consideration. The farmer, therefore, can not hope to shift the burden of this choice. The Fertilizer Control certainly accepts no such responsibility, nor does it recommend particular brands or dealers to consumers. 356 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. THE VALUE OF ANALYSES FOR CONSUMERS. The State fertilizer law gives every consumer the privilege of having samples of commercial fertilizers analyzed by the Control, in return for a nominal fee and the satisfying of certain simple require- ments. This matter has been explained in previous bulletins and will not be repeated here in detail. Applications for further information will, however, be cheerfully answered. It must be admitted with regret that this wise provision has not yet accomplished the object for which it was intended. This conclusion is based on the correspondence with persons sending samples. The greater number of these apparently do not send the sample until after the purchase is complete, so that they have no recourse in case the goods are deficient in any respect. Again, farmers as a rule will not buy on the unit basis, as they have so frequently been advised to do. So that even if the dealer is willing to submit to a rebate, there is no satisfactory basis upon which he can do so. The result appears to be that when deficiencies are reported, the farmer merely becomes disgruntled with his dealer and there is no other result. Whereas, if he bought at so much per unit a simple calculation from the analysis would show exactly what the refund should be and permit of an amicable adjustment. It may be asserted with confidence that where an inspection is in any way efficient, the deficiencies met with tend rather to the commercial than the agricultural injury of the farmer. That is to say, the mere fact that an inspection exists is sufficient in most cases to prevent such gross adulteration as would result in great injury to the crop. But the small deficiencies occurring under the best regulated system of inspection may result in considerable financial loss to consumers. Failure to understand these facts fre- quently renders an analysis worse than useless to the farmer, but their full realization can only result in making the privilege of appreciable value to him. THE UNIT BASIS. The calculation of the commercial value of a fertilizer can only be made on the so-called unit basis. Such calculations consist simply in multiplying the number of per cent of each ingredient by the price per unit and adding the products. The sum thus obtained is the com- mercial value per ton at the prices used. If it is desired to use such a calculation for determining the amount which should be paid for goods, or the rebate to which the buyer is entitled owing to the goods delivered being below the guaranty, it can only be satisfactorily done if a definite price per unit has been agreed upon between buyer and seller. But' for the mere purpose of showing the relative values of goods to guaran- ties, it is not at all necessary that the prices adopted should be the COMMERCIAL FERTILIZERS. 357 exact market prices. Thus it is that the Fertilizer Control in attempt- ing to show the relation between values found and values claimed, uses a schedule which is admittedly only an approximate average of market values. Owing to market fluctuations, differences in cost of delivery at different points, and other causes, the obtaining of true average market prices is an impossibility. But if the reader will bear in mind the true purpose of the valuations reported, these will have served their turn and he will not be led to assume that the Experiment Station is dictating the prices at which goods shall be sold.

The following manufacturers and dealers in commercial fertilizers have obtained certificates of registration under the provisions of the California Fertilizer law for the fiscal year beginning July 1, 1906. A list is also given of the brands of fertilizers and fertilizer materials offered by them for sale. According to the sworn returns of dealers registered for the fiscal year ending June 30, 1906, their entire sales in the State amounted to 16,801 tons. No dealer or manufacturer, except those who have certificates of registration from the University of California, and their authorized * 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 For the purpose of calculating comparative values an average value of 4 cents per pound for phosphoric acid and 17 cents for nitrogen is used on bone meal and tankage ; an average of 4V2 cents per pound is used for phosphoric acid in Thomas phosphate powder.

From July 1 to December 31, 1906, 183 samples of registered fertil- izers and fertilizing materials have been received at the laboratory. Of this number, 8 were sent by farmers under the two-dollar fee pro- vision, 41 were taken by inspectors from purchasers' goods upon the request of the purchasers/and 134 were taken by inspectors from goods in the hands of agents and manufacturers. On 29 samples the analysis as reported was used as a basis of settlement by mutual agreement of buyer and seller. No guaranty was required or given with goods sold 362 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. under such an agreement. It is to be noted that the total number of samples is less than that of the preceding half-year, as reported in Bulletin No. 173, but is greater than the numbers heretofore reported for the fall inspection. For corresponding half-years the increase has been consistent, but owing to the fact that the bulk of the sales are made in the spring that portion of the year will always present better opportunities for the collection of samples. The following classification may be made of samples reported in this bulletin : Complete fertilizers - 94 Bone meal IS Tankage 30 Nitrogenous superphosphate 1 Superphosphate and potash 1 Superphosphate 1 Thomas phosphate powder 2 Dried blood 12 Nitrate of soda 7 Bird guano phosphate 5 Sulfate of potash 3 Bat guano 3 Total 183 DEFICIENCIES. In the analyses of the above samples, the following number of deficiencies greater than allowed by law occur : Available phosphoric acid (total when available is not guaranteed) 7 Total nitrogen 16 Potash 9 In valuation 6 . These deficiencies were found in 24 samples. The fertilizer law allows a deficienc}^ of 0.25 per cent in nitrogen, 0.50 per cent in potash, and 1.00 per cent in available phosphoric acid. REPORT OF ANALYSES.* Available phosphoric acid is not determined in bone meal, tankage, and Thomas phosphate powder, unless requested. The fineness of these materials is determined, fine and medium bone being separated by a sieve of 50 meshes to the inch; tankage by a 25-mesh sieve; and Thomas phosphate powder by a 100-mesh sieve. Some fertilizers containing all three ingredients are rated as tankage, because they are non-acidulated tankage products with potash salts added, and do not carry a guaranty of available phosphoric acid. * The laboratory work in connection with these analyses was largely carried out by Mr. Ludwig Rosenstein, to whom credit is due for his careful and conscientious work. COMMERCIAL FERTILIZERS. 363 Nitrogen in ammonia salts will, in some cases, be found reported when nitrogen in this form is not guaranteed. In some of such cases this form of nitrogen is produced by conversion of organic nitrogen during process of manufacture, and is not to be considered a deviation from guaranty of materials used. Guanos carry more or less nitrogen in nitrates and ammonia salts, and when any appreciable quantity of guano is used the manufacturer should take into account the fact that some nitrogen will show as nitrates and ammonia salts. The failure to take this into consideration may perhaps account for the appearance of these forms of nitrogen in some samples in which only organic nitrogen was guaranteed. The percentage of chlorin is given when it exceeds 0.50 per cent. It is a matter of only technical interest whether chlorin present is from muriate of potash, kainit, or from common salt that may be in some of the materials used. If a manufacturer uses sulfate of potash and uses a tankage with it containing a large amount of chlorin, from a practical standpoint he has lowered the grade of his fertilizer just as much as if he had used muriate of potash instead of sulfate of potash. Chlorin from all other sources is as objectionable as from muriate of potash. However, if muriate of potash is found when sulfate is guaranteed, the fact will be published. The following abbreviations are used in the tables : Bl=blood ; Bn= bone; Fs=fish; G=guano; Super— superphosphate ; T=tankage. Guaranties are entered in italics. Deficiencies greater than allowed by law are entered in bold type. 364 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. ANALYSES AND VALUATIONS.

CALIFORNIA FERTILIZER LAW. CHAPTER CCXXV. — An act to regulate the sale of commercial fertilisers 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 manufacture, 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, available 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 composition of the fertilizer it accompanies. Sec. 2. No person shall sell, offer, or expose for sale in this State, any pulver- ized 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 certificate 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 registry. 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 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 accord- ance 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 Septem- ber, 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 COMMERCIAL FERTILIZERS. 379 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 fertilizing 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 Experiment Station of the University of California shall, upon the receipt of a sample of fertilizer, accom- panied with a nominal fee of two ($2) dollars, furnish to the user of said com- mercial 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 California, 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. G. 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 circumstances 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 prosecu- tion 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 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 com- pliance 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. 380 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION.
