Key benefits

  • Regulates transpiration and prevents water loss from plants
  • Increases plant resistance to drought, low temperatures and pathogens
  • Optimises the use of nitrogen
  • Stiffens stems and reduces susceptibility to lodging
  • Stimulates photosynthesis and assimilate transport
  • Improves yield quality by increasing starch, organic acids, protein, fat, sucrose, carotene, vitamins B1 and C

Optimally balanced composition

Quick and complete solubility in water

Effective integration of macronutrients and micronutrients

Versatile – for use with all types of crops

Perfect addition to soil fertilisation

Technology in practice

For use throughout the growing season, as prevention or intervention; especially when harvesting straw after harvest; before expected precipitation deficit; on light soils – washout of potassium; during symptoms of potassium deficiency
