Alva Agee, Crops and Methods for Soil Improvement
“ Good Soil Conditions.—When the grasses and clovers desired for a sod are sown with small grain, there is competition between them and the grain crop for fertility, moisture, and light. The grain crop is the one that will produce the income the following summer, and naturally is given right of way. The amount of seed is used that experience teaches is best for a maximum yield of grain. Usually this gives a thicker stand of plants than is best for the tiny grass and clover plants that often are struggling for existence down under the taller grain. ”
