Signature Zinc Amino Acid Chelates

Wilchem Signature is a range of Amino Acid Chelates. Amino acids are bidentate chelants - they form two bonds to the nutrient to forms a "chelate ring". The double bond is stronger than a single ionic bond, this protects the nutrient and maintains it in solution. Amino Acid chelates increase nutrient uptake efficiency, leading to increase yield and quality.

Wilchem Signature Zinc is used to correct and prevent zinc deficiency in a wide range of crops. Signature Zinc can be applied via fertigation, furrow injection or foliar applications for broadacre, viticultural and horticultural production where zinc deficiency may occur.

Directions for use:

Foliar sprays are the most effective way of applying Signature Zinc, however it is a Chelate reactions in the soil solution will be reduced making the nutrient more available and for a longer period.



Zinc Deficiency:

Zinc deficiency occurs mainly in high pH soils, sandy soils that are low in organic matter, organic soils (peats) and in over-limed soils. Uptake of zinc decreases with increased soil pH and can be adversely affected by high levels of available iron (Fe). Cereal crops, potatoes, vines and fruit crops grown on high pH sandy soils are particularly sensitive to zinc deficiency.

Deficiency Symptoms:

  • Brown or yellow patches on new growth
  • Patchy appearance of the crop
  • Brown necrotic spots on the leaves
  • Poor seed set - young tillers may die before setting seed.
  • Poor yield/low protein

Compatibility with Agricultural Chemicals:

Signature Zinc is compatible with a wide range of agricultural herbicides and pesticides. Check the Compatibility guide as a reference. Always do a small jar test before preparing a full tank mix.

Other Details:

Liquid fertilizers can be corrosive to metals, so flush equipment clean after use. Avoid contact with eyes and skin. Avoid inhaling fumes. Wash thoroughly with soap and water after handling. Protect from frost. Amino Acids are an organic substance and over time some slight precipitation may occur. Do not store for extended periods in direct sunlight.
