BN POTASSIUM (20%) BIONOVA

BN Potassium contains 20% K2O. In addition to the basic elements N and P, also K (potassium) is crucial for every crop.

Potassium plays an important role in the formation of cells, the regulation of osmosis and the production of carbohydrates. Additionally, potassium is important for the opening and closing of the stomata, which allow excess heat to drain.

A potassium deficiency manifests itself when the plant does not open the stomata sufficiently for vaporization in order to cool. This results in the development of chlorosis on the edges of the leaves which develops into necrosis (death) at a later stage.

In case of an excess of potassium the plant will slow down in its development and subsequently turn dark. An excess also hinders the absorption of other cations (Ca and Mg), which is caused by antagonistic effects.
