Samagrow P (4-8-2)

SamaGROW P is an organic mineral fertilizer rich in phosphate. Phosphorus is a constituent element of nucleoproteins and plays a role in the respiration of plants. Phosphorus promotes root development, bloom, and seed production. In addition, it is a major component of the plant's genetic material (DNA).

SamaGROW P is the perfect fertilizer, combining the advantages of organic matter, trace elements (Fe, Mn, B, Mo, Zn and Cu) and extra phosphate. This will maintain long term soil fertility and ensure optimal availability of phosphate to the plant.

Due to the high organic contents of the minerals, these are released slowly, providing the plant with a gradual source of nutrients for a long period of time. This means no minerals are washed away and there is no risk of leaf or root burn due to a low EC value.

On demand, we can enrich these pellets with mineral or organic fertilizers, humic acids, amino acids or molasses as needed.

This product conforms to the requirements of European Regulation (EC) No. 1069/2009, which, in conjunction with implementing Regulation (EC) No.142/2011, regulates the use of animal by-products, and also conforms to French standard NF U 42-001.
