Potash for Plants
The role of potash in the vital functions of plants is versatile. It’s a sine qua non for all plants, microorganisms, animals and man. Potash uptake is largely a function of its content in soil, mobility and availability to plants.
The physiological role of potash manifests itself in supporting favourable (for the proper function of a cell) physical and chemical properties of protoplasm helping maintain normal metabolism. Potash helps better absorption of nitrogen by plants thus preventing environmental pollution.
Potash participates in the formation of plant cell walls, thickens cell walls, rendering plants more resistant to lodging. Harder cell walls serve to increase resistance to agricultural pests and diseases. Lower potash content in plants is conducive to pest and bacteria infestation of plant tissue. Plants receiving much potash show better resistance to pathogens.
Potash regulates water intake.Plants well-supplied with potash take in less soil water and are more resistant to drought. Potash fertilizers work drastically better when plants get enough water, therefore in areas with intensive irrigation they use significantly less water in agriculture.
As winter comes, plants well-supplied with potash appear to be more robust and with a better developed rootage. Potash enhances plants’ winter-hardiness and their resistance to spring and autumn frosts.
Potash deficiency arrests plant development resulting in nutritional disorders, diminished crop performance and poorer quality yields.
Sufficient application of potash
Activates ferments which take part in the metabolism of nitrogen, and increases proteins in wheat, barley, rice and in the seeds of pulse crops.
Potash stimulates the accumulation of the vegetative mass.
Potash promotes the accumulation of fat in the seeds of sunflower, rapeseed, fruits of palm and olive trees and other oil crops.
Helps increase sugars, vitamin C, B1, carotene, organic acids
Improves taste, colour and pulp consistency of berries and fruit.
Potash strengthens and lengthens fiber in cotton, flax and other technical crops plants.
Potash fertilizers curb by 1.5-1.7 times the accumulation of 137Cs in plants grown on soils contaminated with radionuclide.
… and this is not the whole story.
