Excerpt from Soybeans: Their Effect on Soil Productivity For several reasons this popularity of soybeans, and consequently the interest in their effect on the soil, is likely to continue. Some of these-reasons are: (1) Supported by the many industrial uses dis covered for soybean products, soybeans as a cash crop have brought larger money returns than some other crops in the rotation, particularly oats.

Excerpt from Soybeans: Their Effect on Soil Productivity For several reasons this popularity of soybeans, and consequently the interest in their effect on the soil, is likely to continue. Some of these-reasons are: (1) Supported by the many industrial uses dis covered for soybean products, soybeans as a cash crop have brought larger money returns than some other crops in the rotation, particularly oats. (2) Soybeans make a good legume hay, high in protein and mineral elements. (3) They yield fairly well on soils too acid or too low in productivity to grow alfalfa or clovers successfully. (4) They are outstanding in drouth resistance, usually doing well wherever a good seedbed can be prepared, even in seasons too dry for seedings of alfalfa or clover to survive. (5) Like other legumes, they can obtain from the air a large proportion of the nitrogen they require, provided they are well nodulated. (6) They grow rapidly, are annuals, and therefore may be used as emergency hay or grain crops in late wet springs or at times when clovers and alfalfa have failed. (7) They are resistant to chinch bugs. (8) They serve well as a pasture crop, seeded either alone or in combination with other crops. These are some of the favorable qualities which account for the widespread adoption of soybeans in Illinois; but if soybeans are to be fitted most usefully into Illinois cropping systems, their limitations also must be recognized. In this bulletin both the favorable and the unfavorable aspects of soybeans in relation to the soil are discussed.
