Samagrow K (4-3-8)

SamaGROW K is an organo-mineral fertilizer rich in potassium. Potassium contributes to the strength of the plant. It plays an important role in the resistance of the plant to diseases and weather conditions, and in the taste and shelf life of crops (especially fruits and tuber and bulb crops).

SamaGROW K is the perfect fertilizer, combining the advantages of organic matter, trace elements (Fe, Mn, B, Mo, Zn and Cu) and extra potassium. This will maintain long term soil fertility and promote plant resistance and resilience.

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.

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