GRENA SUPERZOLFO provides an excellent corrective action against alkaline soils by balancing their pH, allowing plants to better assimilate the nutrients present in the soil, and especially avoiding iron chlorosis in calcareous soils, since alkaline soils inhibit the assimilation of micro-elements.
The product ensures a high supply of organic compounds that promote an overall improvement in soil fertility and a continuous availability of essential nutrients.
GRENA SUPERZOLFO also supplies Sulphur (S) as a nutrient; it is well known that a well-nourished plant suffers less from environmental or climatic stress, and this is further supported by the effect of the amino acids contained in the GRENA organic matrix.
