Potassium


Potassium is an indispensable constituent for the correct development of plants, it is therefore present in almost all type of soils, in several forms and with different solubility degrees. The potassium ion is absorbed by the soil through the humus compounds, or through clays or natural zeolites. The deficiency of the element in the soil implies plant atrophy, mainly of the roots.

Potassium can also be found in the animals' cellular liquids in the form of monopositive ion and has an extremely important role in several biological reactions and vital manifestations, such as transmission of nervous pulses to produce muscular contraction. Disturbances in the amount of potassium and sodium, and its compounds, in the living organisms have usually disastrous effects at the metabolic level.
