An Excess Of Nitrogen
Categories:
TILLAGE
Too much nitrogen, due to heavy manuring or
other cause, produces an excessive growth of stalk or straw, at the
expense of grain production, in the case of corn, wheat, and other
cereals. It produces a rank growth of potato vines and partial failure
of the crop of tubers. It produces a tender growth of straw or vine
that invites injury from fungous diseases. It is the rule that soils
have a deficiency in nitrogen, but when there is an excess, the best
cure comes through use of such crops as timothy, cabbage, and ensilage
corn. Heavy applications of rock-and-potash fertilizers assist in
recovery of right conditions, but are not wholly effective until
exhaustive crops have removed some of the nitrogen.
