Potash is an essential nutrient for crop production
A balanced amount of potash increases immunity for various conditions in the crop such as diseases, pest diseases, lack of nutrition, etc.
Potash produces good root development and strong stem growth in the crop, which results in it having a good grip on the soil.
A balanced amount of potash develops water holding capacity of the soil
Potash is an enhancer of crop yield and quality.
The lack of it stops crop growth.
Due to potash deficiency, the old leaf of the crop turns yellow from the edge while the color of younger leaves turns darker, the tissues of the leaves die and later the leaves dry up.
