APPENDIX. ANALYSES AND VALUES OF FERTILIZERS. The truck-farmer is forced to use to a greater or less extent some kind of artificial fertilizer. The following circular, issued by the Department of Agriculture of the State of Georgia, contains information of value to all who purchase and use fertilizers. The circular as issued by the Department contains a column giving the names of the persons for whom the inspection was made. As this information has no permanent value, it is omitted for the purpose of saving space. Some other unimportant omissions have been made in reproducing the circular. ANALYSES AND COMMERCIAL VALUES OF COMMERCIAL FERTILIZERS AND CHEMICALS, Inspected, Analyzed and Admitted to Sale in Georgia to January 10, Season of 1882-3. DEPARTMENT OF AGRICULTURE, ATLANTA, GA., January 20th, 1883. EXPLANATIONS OF THE TABLES OF ANALYSES. The tables commencing on page 254 show the analyses and calculated relative commercial values of all fertilizers and chemicals inspected, analyzed and admitted to sale, to January 10th, 1883. In addition to the chemical determinations and commercial values, a column has been added which shows the numbers of tons represented by the samples whose analyses are given. This information may sometimes be important to farmers and other purchasers. RELATIVE COMMERCIAL VALUES. After very extended correspondence and careful consideration, it has been thought proper to reduce the valuations of ammonia and phosphoric acid from those of last season. The following prices per pound of the valuable ingredients or elements of plant food found in the fertilizers by analysis, have been adopted as a practical approximation to their true value at Savannah, viz: It is often desirable to know the relative amounts paid by a farmer for the several valuable ingredients in a ton of fertilizers. The following is a simple rule: Multiply the per centage of ammonia, as given in the tables, by $4.00, the available phosphoric acid by $2.00 and the potash by $1.2, or $1.1-5, and the respective results will show the value of each ingredient in a ton. Thus: Suppose a fertilizer analyzes as follows: TABLES OF ANALYSES AND RELATIVE COMMERCIAL VALUES OF COMMERCIAL FERTILIZERS, CHEMICALS, ETC., INSPECTED, Soluble Pacific Guano.

A good, finely-ground bone meal is worth about $40.00. |
