Potassium Deficiency in Row Crops 

Potassium, or potash, is an important nutrient for Arkansas’ major row crops, and a deficiency can significantly reduce yields. Inadequate potassium nutrition can limit yields, similar to inadequate nitrogen. And for legumes like soybeans, which absorb nitrogen from the air and convert it into a nutrient through nitrogen fixation, potassium becomes the most important fertilizer nutrient to ensure optimum yields.
Learn more about potassium deficiency and how to identify it in some of the major row crops in Arkansas, including corn, rice, cotton and soybean.
