Potash deficiency, also known as potassium deficiency, is a common problem. It can be caused by soils that lack colloids, which hold potassium ions in place. This can occur in soils that are peaty, chalky, or low in clay content.
If your soil lacks potassium, then you may want to consider applying a high potash fertilizer to your crop. This element is vital to plant health, and it helps to produce enzymes that aid in water retention and food processing. It also helps improve the color and taste of your crops. When you add potash to your soil, you should do so during early spring to late summer, when your plants are in active growth.
To determine if your soil is deficient in potash, you can consult a horticulture specialist. You can also visit your agricultural extension office to get recommendations. Adding potash to soil on a monthly basis will help many types of fruit trees and vegetables grow well.
You can also purchase high potash fertilizer from your local garden center. High potash fertilizer is available as a granular fertilizer. You can also apply it directly to the soil, and you can till it in. Depending on the amount of potash deficiency, you can use up to 20 pounds of potash per square foot.
A high potash fertilizer can help cure a plant's potash deficiency. It can improve the plant's growth and improve its resistance to disease. It can also prevent the leaves from turning brown or yellow. When applied to plants, a high potash fertilizer can promote flowering and cure severe deficiencies.
