Corn's Potassium Deficiency (K) - Cibra Fertilizantes

Corn’s Potassium Deficiency (K)

The importance of potassium (K): it is responsible for the efficient use of water, increases plant resistance to lodging and tolerance to pests and diseases.

Potassium (K) deficiency shows an inverted “V”-shaped yellowing (chlorosis) in old leaves, and later turns into necrosis.

In cases of severe deficiency, chlorosis may not be noticed at first, progressing directly to tissue death. Both symptoms progress from the edges to the base of the leaf. In the ears there is a reduction in size and the grains at the tip of the ear do not develop properly.
