چکیده
The continuous mono-culture cropping without organic matter addition could deplete the plant available micronutrient reserves in sugarcane-growing soils. This study attempted to investigate current status of availability commercial sugarcanegrowing Alfisols at Sevanagala, Sri Lanka, and assess potential these soils become deficient future. Sugarcane-growing covering both irrigated rain-fed systems, low humic gley (LHG) reddish-brown earth (RBE) were included this study. A stratified random sampling technique, systems soil orders, was employed obtain 263 samples. Soils analyzed for Fe, Mn, Zn, Cu contents using standard DTPA procedure. Available Fe Zn exhibited significant differences among orders. They significantly higher under RBE (75 mg/kg 1.1 respectively) when compared those LHG (43 0.6 respectively). Mn sufficient levels sugarcane most In contrast, patches (< 0.1 mg/kg) within great groups studied area. results indicate that appropriate nutrient management practices are required overcome deficiencies Sevanagala mitigate any negative effects on crop yield quality
