Abstract:
The mineralization of organic matter and the subsequent release of various nutrients increased the concentration of soluble salts. Because a number of other variables, including soil temperature, porosity, soil texture, soil moisture, and soil mineral content, also have an impact on soil electrical conductivity, soil pH has a negative power function and linear connection with soil electrical conductivity. The extent of N addition leads to the depletion of all the key nutrients. Straw is the sole organic substance that, supplies 30 to 35% of the phosphorus taken up by the rice plant remains in vegetative plant parts at crop maturity. The assimilation of crop residues during fallow periods improves the soil's ability to transfer phosphorus (P) to the subsequent crop under intensive cropping systems, reducing the P losses caused by burning crop residues, which amount to roughly 25%.
