一个field study was carried out on a sandy loam soil at the KVK farm Janjgir Champa, Chhattisgarh to study the effect of enriched fly ash (FA) on  rice and soil characteristics of inceptisol during kharif 2013-14. The test crop was rice var. MTU-1010. The application of different treatment FA combinations increased paddy yield compared to 100% GRD. However the control treatment failed to produce the yield in degraded land. Among the treatments, the 75% GRD + 60t FAha-1+5t FYMha-1 gave highest paddy yield (42.6 q ha-1) than all other treatments. The straw yield was not significantly influenced by FA treatments, but the beneficial effect of enriched fly ash on higher rice straw yield was observed. Application of  75% GRD + fly ash@ 60 t ha-1 + FYM @ 5 t ha-1 recorded the highest soil available phosphorus, potassium and zinc compared to other treatments and soil available N was highest in application of 75% GRD + fly ash@ 40 t ha-1 + FYM @ 5 t ha-1. The soilavailable Cu,Mn and Fe content were not significantly influenced by different combination of FYM, FA and Fertilizers. The organic carbon storage on degraded land increased significantly with the application 75% GRD + fly ash@ 60 t ha-1 + FYM @ 5 t ha-1 (6043.33 kg ha-1)  than the 100% GRD  and control.
