This experiment was conducted to investigate the residual effects of organic amendments on soil fertility and properties following sweet corn cultivation in tropical agroecosystems. Continuous sweet corn farming without adequate organic amendment often leads to soil degradation, nutrient depletion, compaction, and reduced biological activity. The use of organic amendments such as compost, manure, and crop residues help counter these effects by improving soil chemical, physical, and biological conditions. These benefits such as nutrient release, enhanced soil structure, and increased microbial activity extend beyond the initial cropping cycle, making them particularly valuable in resource- limited farming systems. Residues from organic amendments contribute to sustained soil fertility, better crop yields, and reduced reliance on synthetic fertilizers. They enhance water-holding capacity, promote root development and improve soil resilience against drought and erosion.These improvements not only benefit subsequent crops but also reduce production costs and support environmental conservation through carbon sequestration and lower greenhouse gas emissions. In conclusion, incorporating organic amendments into soil management offers both economic and ecological advantages for long-term agricultural productivity.
