Κωδικός: 025

STRONG is a solid natural activator which contains 97% potassium humate. It comes from natural, plant deriving, brown coal deposits and it is rich in macro and micronutrients and trace elements (K, N, Ca, Mg, Fe, S, Mn, Zn, Cu, B, and Mo). STRONG dissolves rapidly in water (100% water soluble) and does not clog the filters. It is suitable for all irrigation and fertigation systems.

  • It increases cation exchange and
  • water retention capacity of plants.
  • It stabilizes soil pH against increased acidity
  • due to frequent fertilizer applications.
  • It improves retention and assimilation of the essential nutrients by plants, reducing applied fertilizers loss due to leaching and run-off.
  • It promotes good soil structure formation.
  • It stimulates beneficial microbial activity and root growth.
  • It promotes nutrient uptake by plants in hydroponic cultures.
  • It oxygenates the root system more efficiently and prevents possible rots.
  • It enhances calcium penetration and retention by soil.
  • It transfers aluminum to subsoil.
