Abstract: A study was conducted to determine soil organic carbon and nutrient content in soil in a long term fertiliser experiment in relation to inorganic and integrated application of organic manure in rice-rice system on an acidic sandy loam soil. The fertilizer treatment included balanced, imbalanced fertilisation and integration of organic manure like FYM along with soil conditioner and absolute control. The results showed that N alone or N and P and K did not have any significant effect on soil organic carbon and N but significantly higher than absolute control. The available N was 32.25% higher in NPK+FYM than in 100%NPK in comparison to 10.24% increase with super optimal dose of fertiliser. Only FYM along with NPK registered a buildup of available P in soil compared to other treatments. Buildup of available K in soil over a period 11 years was observed. The FYM along with lime treated plot showed higher microbial population. The grain yields were significantly influenced by the treatments. Integration of inorganic along with organic manure proved superior for better crop growth and yield.
