Green manures in potato rotations
- 11 Downloads
From the evidence at hand it seems to be a practical procedure to use non-legumes as green manures for potatoes. Non-egumes can be grown on soils at a pH of 5.5 or lower more successfully than legumes. A rotation can be arranged which, according to our present knowledge will escape danger of wire worms and grubs.
The use of non-legumes, such as corn is advocated where legumes have failed to maintain the soil in proper physical condition, or where legumes do not thrive because of the soil reaction, or where wire worms have appeared because sod or small grains were part of the rotation.
