Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell

Bulletins 4000 -

Potassium plays a major role in plant growth. It maintains the solutions in plant cells at ionic strengths suitable for maintaining strong plant walls and for the proper functioning of leaf pores (stomata) and plant processes such as photosynthesis, transport of sugars and enzyme activation.

Potassium does not become a direct part of the plant structure but acts to regulate water balances, nutrient and sugar movement in plant tissue. Plants deficient in potassium cannot use other nutrients and water efficiently. They are less tolerant of stresses such as drought and waterlogging and are more susceptible to pests and diseases.
