- 12. Effect of organic ammendments in soil. (i) The decomposition of organic matter, evolution of CO2 and certain organic acids. (ii) Lowering of pH and the release of cations by solubilization of CaCO3 and other soil minerals. (iii) Replacement of exchangeable Na by Ca and Mg and thereby lowering the ESP. (iv) Physical properties like bulk density, porosity, void ratio, water permeability and hydraulic conductivity are significantly improved. (v) Increases soil aggregation and aggregate stability; increases the CEC (the ability to attract and retain nutrients); and contributes N, P and other nutrients.

Vital role of soil organic amendments • Improve soil structure and aeration • Increase water-holding capacity • Increase availability of water to plants • Reduce compaction and hardpan conditions • Improve drainage • Alkali soil reclamation • Release of “locked” nutrients • Better chemical incorporation • Better root development • Higher yields and quality

- 30. CONCLUSION Application of organic amendments improve the physical, chemical and biological properties of soil. The application of urban compost @ 11t/ha resulted in higher yield and improved plant growth of sweet sorghum. Application of organic manures significantly reduced the soil pH and increased the soil organic carbon content , which were higher than plots treated with recommended NPK through fertilizers in rice crop. Available N , P and K, exchangeable Ca Mg, Na total Fe, Mn, Zn and Cu of soil after harvest of crop were significantly higher in organic manures applied field as compared to recommended NPK through fertilizers. Organic amendments supply all the essential nutrients for plants growth. This indicated that the application of organic amendments improves the soil quality, plant growth and yield of crop.
