Ameliorating Sandy Loam Soils: Assessing Soil Nutrient Dynamics and Crop Performance under Variable Rates of Hydrogel, Humic acid and Biochar
M. Ramya, P. Nideesh & N. K. Binitha · International Journal of Plant & Soil Science · 2026
Background: Sandy loam soils are generally low in organic matter and have poor water and nutrient retention, which limits crop productivity. Soil amendments such as hydrogel, humic acid, and biochar are increasingly used to improve soil quality and enhance plant growth. However,...
