CHALLENGE® is an NPK organo-mineral fertilizer with magnesium and zinc, particularly suitable on extensive crops such as wheat, corn, sugar beet, in soils with low potassium level; it is advised to meet the increased needs of phosphorus and potassium required by young plants nursery: vineyard, fruit trees, citrus, etc.

Functions: Fertilizer

Chemical Family: Nitrogen, Potassium Salts

Product Highlights

It speeds up the responsiveness of roots and crops starting in the early stages of the growing period. SIAPOR CHALLENGE, with POTASSIUM CHLORIDE, should be used on any crops less sensitive to salinity, preferably checked through analytical controls. NPK, Mg and Zn nutritive units, while reacting with the humified organic matter (humic and fulvic acids and humins), acquire a considerable degree of protection thus allowing an optimal agronomic yield.

This allows

  • high and extended nutrient availability for the entire crop cycle;
  • reduction of losses due to insolubility, leaching and evaporation;
  • flexibility of 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: 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 absorption, beneficially fostering crop growth in the early vegetative stages.
