Title:
Potassium: The Overlooked Nutrient in Crop Production

Abstract:

Although potassium (K) is listed among the top three macronutrients (N-P-K) needed for crop production, nitrogen (N) and phosphorus (P) receive most of our attention. This is partly because N and P have potential to cause long-term environmental implications. Also, N and P get incorporated into key complex molecules within the cell such as DNA, proteins, enzymes, etc. In contrast, K rarely poses a threat to the environment. It remains in the plant and animal tissues in its ionic form K+. When crop and animal residues decompose on the soil surface, the soluble K will seep into the soil.
