NIH Zinc deficiency Generally, the first symptoms of zinc (Zn) deficiency in wheat appear on the middle-aged leaves, but considerable variation exists between individual plants; some plants produce symptoms in both old and middle-aged leaves simultaneously. Causes of Zinc Deficiency in Plants Here are the factors found to be responsible for zinc deficiency in plants: Soil Temperature. Chlorosis appears on the lower leaves first, and then gradually moves up the plant. Although zinc requirements vary among crops, zinc leaf concentrations (on a dry matter basis) in the range 20 to 100 mg/kg are adequate for most crops. Leaf tips will turn yellow and necrosis will set in. [1], Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption (calcareous soils, highly weathered soils, vertisols, hydromorphic soils, saline soils). Zinc is essential for both plants and animals because it is a structural constituent and regulatory co-factor in enzymes and proteins involved in many biochemical pathways.
