Symptoms of crop zinc deficiency?
Symptoms of crop zinc deficiency: first, it appears in the old leaves, the growth is inhibited, the plants are short, the internodes are broken, the tillers are few or delayed, the leaf veins lose green, and there are albino symptoms. Maize and rice were sensitive to zinc deficiency, followed by dicotyledons potato, tomato and sugar beet; Perennial fruit trees are sensitive to zinc, such as citrus, grape, peach and apple. Zinc deficiency has a great impact on fruit quality.

Crop molybdenum deficiency symptoms?
Symptoms of molybdenum deficiency in crops: first appear in the leaves in the middle of the old leaves or stems, and gradually develop to the young leaves and growth points. The plants are short and grow slowly. The leaves have yellow or orange spots of different sizes. In serious cases, the leaf edges wither, the leaves twist into a cup, and the old leaves thicken, scorch and die. Leguminous crops have the largest demand for molybdenum, and cruciferous cauliflower and cabbage also have high demand for molybdenum. Molybdenum fertilizer also had a great effect on the quality of winter wheat.

Scientific management of fertilizer?
Fertilizer can be used alone or mixed with each other, or even mixed with herbicides and pesticides. Some fertilizers, such as carbon and ammonia, are unstable and easy to volatilize. Some fertilizers are easy to agglomerate and reduce fertilizer efficiency under high temperature and high humidity conditions. Therefore, the conditions of high temperature and high humidity should be avoided during the storage and transportation of fertilizers.
