A knowledge of the cropping history and past management of the soil in manv instances will greatly aid in arriving at any definite. Fig. 35.—This crop yielded 75 bushels of corn per acre. Rows were four feet apart and hills in the rows three feet apart—one stalk in each hill. The secret—each stalk pro- duced a little less than IK pounds of ear corn. (Mississippi.) conclusion. For example, alfalfa failure on some soils may be due to no other cause than the absence of alfalfa nodule- forming organisms. The Secret in Growing Good Crops.—The secret of a good yield of corn consists in causing each stalk in the field to produce at least one good ear (Fig. 35). To attain this object a good farmer, because of experience, selects a workable and desirable soil, pre- pares a good seed bed, increases the richness of the soil by adding manure or commercial fertilizers, cultivates the growing crop as well as he knows how, and trusts to the weather for the rest (Fig. 36)..
