GRENA VERDE 4.5.8 S (18 CaO) is obtained by reacting the GRENA organic matrix with high-quality mineral products: soft natural phosphate, potassium sulphate and dolomite, all products permitted in organic farming.
The balanced supply of organic nitrogen, Phosphorus and Potassium makes GRENA VERDE an excellent product for autumn-winter fertilisation.
The presence of CaO activates the amino acids in the GRENA organic matrix, thereby promoting plant growth, enhancing fruit flavour and
at the same time strengthening the plant’s natural defences.
