| | Potassium deficiency (plants) - Wikipedia, the free encyclopedia |
 | | Potassium deficiency, also known as potash deficiency, is a plant disorder that is most common on light, sandy soils, as well as chalky or peaty soils with a low clay content. |
 | | The deficiency most commonly affects fruits and vegetables, notably potatoes, tomatoes, apples, currants, and gooseberries, and typical symptoms are brown scorching and curling of leaf tips, and yellowing of leaf veins. |
 | | Deficient plants may be more prone to frost damage and disease, and their symptoms can often be confused with wind scorch or drought. |
