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.
