17 240 AGRICULTURE figures are based on the cost of an equal amount of com- mercial fertilizer. It is true that not all the fertility taken from the soil by farm crops can be returned by using the manure from the feeding of crops, but the greater part of it can be. The manurial value of different farm products, based on the cost of commercial fertilizers, is shown in the following table: {Farmers' Bulletin 193, U. S. Dept. of Agriculture.) Value of fertilizer in ton Phosphoric Product Nitrogen ...acid Potash Total Meadow hay $ 3.47 $ 0.57 $ 1.06 $ 5.10 Clover hay 6.83 .78 Wheat bran 8.35 3.82 Linseed meal 17.87 2.25 Cottonseed meal 23.06 3.96 Wheat 6.38 1.11 Oats 6.21 .87 Corn 5.62 .83 We see from the above table that the farmer who sells a ton of meadow .hay loses from his. farm, fertilizer that would cost about five dollars if purchased in commercial form. If he sells clover hay, he loses almost as much value in fertilizer as his hay brings him. If he pays twenty dol- lars a ton for wheat bran he gets over thirteen dollars' worth of fertilizer, leaving the feeding cost about seven dollars.
