Two Legumes In The Rotation

Categories: CROP-ROTATIONS

If all the crops of this five years'

rotation, excepting wheat, were fed on the farm, and if all the manure

were saved and rightly applied, there would be little or no difficulty

in maintaining fertility, provided the soil were friendly to clover.

The fact is that much such land has grown poorer, and it is known that

another legume is needed in the rotation. The substitution of the

soybean or cowpea for the oat crop gi
es excellent results. It makes a

large supply of rich hay, and it fits the soil nicely for winter grain.

The use of the breaking-plow is escaped. The surface of the land is in

good tilth, especially if the legume was planted in rows so that

cultivation could be given. A cutaway harrow, run shallow, and a roller

make the seed-bed. Near the southern edge of the oat belt this

substitution gives more value in the crop following corn, and at the

same time conserves soil fertility.



Where land is thin, a four years' rotation of corn, soybeans or

cowpeas, wheat, and clover is one of the best, because it contains two

leguminous crops, and because one of them favors the wheat which

follows and the clover seeded in the wheat.
