Korian is an exclusive mixture of polyphenols of vegetal origin (tannins) that streights the plants to the formation of an efficient and active root system on any soil and climate condition.

Korian allows to create the conditions for a more complete availability of nutritional elements present in the soil to the plants. In particular, it acts on the mobilisation of phosphorus and calcium present in the soil.

The constant emission of new roots allows for an optimal development of the plant, even in case of abiotic stresses and in soils infested by nematodes.
