Product Highlights

The product is particularly suitable in young plants nursery: vineyard, fruit trees, citrus, etc., to foster the freeing of the root system and to speed up the start in the early stages of the cycle of herbaceous crops. NPK, S, Mg and Zn nutritional units, while reacting with the humic part of the organic matter (dried manure, dried poultry manure, humic peat) acquire a significant degree of protection, thus allowing optimal crop yield.

This allows:

  • high and extended nutrient availability for the entire crop cycle;
  • reduction of losses due to insolubility, leaching and evaporation;
  • flexibility to the fertilizing cycle with the option of applying it before the normal period of nutritional use;
  • saving of fertilizer usage.

The addition of meso and micro-elements can raise important physiological processes:

  • SULFUR (SO3 10%) contributes by feeding the plant with a better amino acid metabolism on a cellular level.
  • MAGNESIUM optimizes the photosynthetic cycle and the phosphate metabolism.
  • ZINC is an active element in many enzyme systems: it encourages the auxin growth, directly affects the nitrogen metabolism and the phosphorus uptake, beneficially fostering crop growth in the early vegetative stages.
