Wheat and Rice Response to Potassium in Vertisols Results from 120 Plot Pairs Across Bhopal , Jagtial , Jabalpur , and Raipur Districts , India

21/45 Abstract The soil quality and fertility in the country are of utmost importance. Declining soil fertility is one of the primary factors that directly affect crop productivity, and fertilizer use is a key factor in order to ensure soil fertility and productivity. Potassium (K) depletion in soil is also a major factor in declining soil fertility. Degradation of soil due to significant nutrient demands by crops and imbalanced fertilizer application is common in the arable lands of India. While practices of nitrogen (N) and phosphorus (P) application have been established and disseminated, K crop and soil requirements are largely ignored. Research Findings
