Zinc is an essential element in plant nutrition. Crops grown in Zinc deficient soils will suffer large losses of yield and quality. Moderate Zinc deficiency, even when visual deficiency symptoms are not present, can cause significant yield losses.
Zinc is a micronutrient and therefore needed in small quantities by crops. Though only a relatively small amount of zinc is needed these critical levels are essential to obtain good quality and high yielding crops. Corn, beans, citrus, deciduous fruit trees, flax, grapes, hops, onions, pecans, and pine are very sensitive to inadequate Zinc nutrition. Mildly sensitive crops are alfalfa, clovers, cotton, potatoes, sorghum, sugar beets, soybeans and tomatoes. Crops annually remove Zinc from the soil and this requires the amount of zinc in the soil and in crop tissues to be regularly monitored to insure adequate levels. Particular attention should be given to zinc levels in high pH alkaline soils, limed acid soils, and soils with naturally occurring free lime as these soils are often zinc deficient. High soil
