FOREWORD By the provisions of section nine of the act creating the State Department of Agriculture (approved Ma}^ 16, 1919, Stats. 1919, p. 542) the Director of Agriculture ". . . is vested with the power and is charged with the duty of administering and enforcing ..." the state law regulating the sale of commercial fertilizers (approved March 20, 1903, Stats. 1903, p. 259), and all acts amending or supple- menting said act. Although the transfer of functions legally took place on July 20, 1919, an arrangement was made with the Agricul- tural Experiment Station to postpone the actual transfer until July 1, 1920, on account of lack of funds and proper housing for the laboratory equipment. I am deeply appreciative of the work of the Director of the Agri- cultural Experiment Station and his associates in administering the fertilizer control law during the fiscal year ending June 30, 1920, report of which is made in this publication. My duty of correlating the administration of state regulatory measures pertaining to agriculture, as definitely outlined by legislative action, was carried out in respect to the fertilizer control law by actively assuming its administration on July 1, 1920, and transferring the necessary office and laboratory equipment to Sacramento. Reports of analyses of commercial fertilizers and other publications pertaining to the operation of the law will be issued hereafter by the State Department of Agriculture, Sacramento, to which address all communications on these subjects should be sent. G. H. Hecke, Director, State of California, Department of Agriculture. Sacramento, November 22, 1920.

DORE This bulletin comprises the results of the fertilizer inspection work of the California Fertilizer Control* for the fiscal year ending June 30, 1920. PURPOSE AND FUNCTIONS OF THE FERTILIZER CONTROL The duty of the Fertilizer Control is : First. — To issue certificates of registration to manufacturers and dealers who have complied with the law by filing a sworn statement of the composition and sources of the fertilizers they wish to sell. Second. — To analyze these fertilizers as found in the open market and publish the results for the information of the public. If a manu- facturer sells fertilizers which are materially below his guarantee in composition or value he is subject to prosecution and fine. By this means it is intended to insure to purchasers that the fertilizers they buy shall be substantially as represented. By a study of the reports of analyses of fertilizers the consumer should be able to determine whether the materials he buys are sold for a fair price, and whether he obtains fertilizers of the desired composition. In short, the function of the Fertilizer Control is to see that the manufacturer gives the consumer a square deal. MAINTENANCE OF GUARANTEES Every manufacturer is required by law to guarantee the percentage of nitrogen, phosphoric acid, and potash in the fertilizers he sells. Owing to difficulties of sampling and analysis the law permits a maximum deficiency of 0.25 per cent nitrogen, 1.00 per cent phos- phoric acid, and 0.50 per cent potash from the figures guaranteed. Greater deficiencies than these are regarded as infractions of the law and are indicated in the report of analyses in black-faced type. Some manufacturers uphold their guarantees better than others. The following table is a condensed report of the deficiencies found in the main table of analyses. It summarizes the work done in this labora- tory on each manufacturer 's goods. The columns headed Deficiencies — * General Laws of California, Oct 1157, Statutes of 1903, p. 259 et seq., approved March 20, 1903. 94 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION per cent of possible, may be used for comparison of the various com- panies as to probability of meeting their guarantees. The other col- umns are necessary to show how these figures were obtained. In cases where very few analyses are reported for a manufacturer the figures should be taken with caution, as perhaps not properly representative. When several samples of one manufacturer's goods were analyzed the figures may be accepted as probably a fair indication of the reliability of his guarantee. In general, manufacturers have more than maintained their guar- antees in the past, so that an average of all the analyses would show a substantial increase over the amount guaranteed.

Fertilizers sold on station analysis, and some others, are not given a valuation in the table of analyses, hence the number of such samples is deducted from the total number analyzed in computing deficiencies in valuation. Bulletin 327 COMMERCIAL FERTILIZERS 95 SUMMARY OF DEFICIENCIES In the analyses of the above samples the following number of deficiencies greater than those allowed by law occurred : Available phosphoric acid (total when available is not guaranteed).... 26 Total nitrogen 56 Potash 4 In valuation 43 These deficiencies were found in 76 samples out of a total of 365 collected samples. Of the total number of valuations reported in this bulletin 64 per cent are above the amount guaranteed, while 36 per cent fall below. MECHANICAL CONDITION OF FERTILIZERS Fineness is one of the essential qualities of a good fertilizer. It may be assumed that the finer the material the higher its availability, hence the consumer should insist on having finely ground fertilizers. Unfortunately, some manufacturers are at times careless in this matter. The insistent demand of the consumer is the most effective means of correcting such carelessness. Besides the low agricultural availability of coarse fertilizer and the difficulty in applying them, it is almost impossible to obtain ade- quately representative samples of such goods for analysis. This is a prolific source of dissatisfaction and disagreement between buyers and sellers. During handling and transportation a coarsely ground tank- age will separate so that the top of the sack contains the light coarser material, high in nitrogen, while the bottom contains the finer parts of bone, high in phosphoric acid. A mixture of coarse bone meal with sulfate of potash will separate into coarse bone at the top and excess of potash at the bottom. One of the chief reasons for the work of the fertilizer manufacturer is that he is better prepared than the farmer to grind and mix the goods he sells, and the farmer should insist that he do it well. CAUTION IN REGARD TO LABELING FERTILIZER PACKAGES The law expressly states that every package of fertilizer shall be accompanied by a plainly printed label giving the brand name, analy- sis, and source of the materials in the package. This requirement is not satisfactorily met by some manufacturers and dealers. Farmers are hereby cautioned that if they buy improperly or inadequately labeled fertilizers or goods not sold by properly registered dealers or 96 UNIVERSITY OP CALIFORNIA EXPERIMENT STATION their authorized agents they lose the protection afforded by the Fer- tilizer Control. Consumers should insist that fertilizer tags show plainly both the percentage and the derivation of each ingredient. A verbal statement given by selling agent should not be accepted as adequate. The honest manufacturer is willing to guarantee his goods properly, and the farmer will best serve his own interests by dealing with no other. FEKTILIZER VALUATIONS One per cent of a ton, 20 pounds, is called a "unit." Computation of the value of a fertilizer is simplified by use of the "unit." To find the commercial value of a fertilizer, multiply the per cent of each ingredient by the price per unit and add the products. The sum thus found is the value per ton at the prices used. If it is desired to use such calculations 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 satisfac- torily 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 guaranties, it is not at all necessary that the prices adopted should be the exact market prices. Thus it is that the Fer- tilizer Control in attempting to show the relation between values found and values claimed uses a schedule which is admittedly only an approx- imate average of market values. Owing to market fluctuations, dif- ferences in cost of delivery at different points, and other causes, it is impossible to obtain true average market prices, but if the reader will bear in mind the true purpose of the valuations reported these will have served their purpose and he will not be led to assume that the experiment station is dictating the prices at which fertilizers shall be sold. SCHEDULE OF VALUES FOR 1919-1920 Per pound Per unit Nitrogen from blood $0.45 $9.00 Nitrogen from tankage and bone 40 8.00 Nitrogen from sulphate of ammonia 25 5.00 Nitrogen from nitrate of soda 25 5.00 Phosphoric acid, available from rock super 06 1.20 Phosphoric acid, total from bone or tankage 07 1.40 Potash, water soluble 15 3.00 SCOPE OF INSPECTION During the year 365 samples of fertilizers and fertilizing materials were received and analyzed at this laboratory. Of this number 6 were sent by farmers under the two-dollar fee provision, 81 were taken by inspectors from purchasers' goods upon the request of the purchasers, Bulletin 327 COMMERCIAL FERTILIZERS 97 and 258 were taken by inspectors from goods in the hands of agents and manufacturers. Twenty samples of a miscellaneous nature are omitted from the tables. The following classification indicates the nature of the samples reported in this bulletin : Bat guano 4 Bird guano 3 Blood 25 Bone meal 23 Complete fertilizer 127 Fish meal 29 Garbage tankage 3 Incomplete mixed fertilizer 50 Nitrate of soda 10 Sulphate of ammonia 11 Superphosphate 4 Tankage 56 REGISTERED MANUFACTURERS AND DEALERS The following manufacturers and dealers in commercial fertilizers obtained certificates of registration under the provisions of the Cali- fornia Fertilizer Law for the fiscal year beginning July 1, 1919. "With each a list is given of the brands of fertilizers and fertilizer materials offered for sale. According to the sworn returns of dealers registered for the fiscal year ending June 30, 1919, their entire sales in the state amounted to 43,126 tons. Practically complete returns for the year ending June 30, 1920, indicate sales aggregating 58,636 tons. The California Fertilizer Act provides that fertilizers cannot be legally sold in this state, except by those manufacturers and dealers, and their authorized agents, who have obtained certificates of regis- tration from the University of California. No person or company has a right to use any registration number except in connection with the firm name to which the registration certificate of such number has been issued ; and no person or company to whom a registration number has been assigned has a right to allow any other person or company to use said registration number. Any number so used is a fraud. No agent has a right to use his principal's registration number in con- nection with his own name. By act of the Legislature of 1919 the administration of the Cali- fornia Fertilizer Act has been transferred to the State Department of Agriculture and the duties connected therewith have been assumed by that office since July 1, 1920. All correspondence concerning the registration, manufacture, sale, and analysis of fertilizers should, accordingly, in the future be addressed to Division of Chemistry, State Department of Agriculture, Sacramento, California. 98 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION Agricultural Chemical Works, Los Angeles, Cal.

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. Nitrogen in ammonium 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 the process of manufacture, and is not to be considered a deviation from the guaranty. Guanos carry more or less nitrogen in nitrates and ammonium 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 ammonium salts. The failure to take this into consideration may 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 a tankage with it containing a large amount of chlorin, from a practical standpoint he has changed the quality of his fertilizer just as much as if he had used muriate of potash instead of sulfate of potash. Chlorin from all other sources has the same effect as if 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 : Bat G = bat guano, Bl = blood, Bn = bone, Fs = fish, G = guano, H = hoof, Min Phos = mineral phosphate, Super = superphosphates, T = tankage, CSM = cotton seed meal.
