Benefits of Zince Sulfate 20: Download Fact Sheet

Zinc functions in plant:

  • Essential in the synthesis of protein
  • Promotes seed and grain formation
  • Has a key role in plant maturity
  • Required for regulation of growth and enzyme systems
  • Transformation of carbohydrates
  • Aids in respiration

Zinc can be deficient in:

  • Sandy, low organic matter, eroded soils
  • High soil pH
  • High levels of phosphorus or areas of high applications
  • Cold, wet or poorly drained soils

Symptoms:

  • Interveinal chlorosis
  • Shortened internodes
  • With zinc being mobile in plants, oldest leaves affected first
  • Formation of small leaves
  • Mottling in broad leaf crops

Critical levels in plant and soil tests:

  • Plant Tissue: parts per million (ppm)
    • Critical levels at about 20-70 ppm
    • Corn: 20-70 ppm
    • Beans: 20-60 ppm
    • Wheat: 25-40 ppm
  • Soil Test: parts per million (ppm), 0-6”, Mehlich III extraction
    • Deficient: <1.5 ppm
    • Marginal: 1.5-4.0 ppm
    • Sufficient: >4.0 ppm
