SamaGROW CUSTOM BIO is an ecological fertilizer that allows customers to select the NPK composition most suited to the needs of the crops.

SamaGROW CUSTOM BIO is the perfect fertilizer, combining the advantages of organic matter, trace elements and a user-determined NPK ratio. This will maintain long term soil fertility and promote plant growth.

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.
