Abstract

An incubation study on the topic entitled, “Effect of organics on physico-chemical properties of Inceptisol” was carried out at Department of Soil Science and Agricultural Chemistry, Post Graduate Institute, MPKV, Rahuri, during 2020-21. The experiment was laid out in a complete randomized block design (CRD) with three replication and seven treatments. The treatment comprised of Soil + FYM @ 10 t ha-1 (T1), Soil + Vermicompost @ 5 t ha-1 (T2), Soil + Poultry manure @ 5 t ha-1 (T3), Soil + Press mud compost @ 5 t ha-1 (T4), Soil + Goat manure @ 5 t ha-1 (T5), Soil + Urban compost @ 10 t ha-1 (T6) and Absolute control (T7). The results of research indicated that incorporation of organic manures to soil influenced all the properties of soil significantly. The effects of organic manures on soil varied with organic material and incubation period. The application of FYM @ 10t ha-1 significantly improved the soil aggregate stability (MWD) and available water content (0.94 mm and 14.00% respectively). The application of FYM @ 10 t ha-1 recorded significantly lower pH (7.85). However, the application of vermicompost @ 5 t ha-1 was at par with treatment FYM @ 10 t ha-1. The significantly highest EC was recorded with the application of press mud compost @ 5 t ha-1 (0.41 dS m-1). The application of poultry manure significantly influenced soil available N, P and K content. The organic carbon content significantly increased at 15 days of incubation and further decreased from 30 days of incubation. The highest organic carbon content was observed with application of FYM @ 10 t ha-1 (0.69 % at 15 days of incubation). The application of FYM @ 10 t ha-1 significantly increased the Fe and Zn content in soil (5.39 mg kg-1 and 0.72 mg kg-1 respectively). The Mn content was improved with the application of poultry manure @ 5 t ha-1 (7.78 mg kg-1) and application of urban compost @ 10 t ha-1 recorded significantly highest Cu content (0.72 mg kg-1).

Conclusion

The application of FYM @ 10 t ha-1 to soil (Inceptisol) was found superior as evident from higher values of mean weight diameter, available water content, soil pH, organic carbon, iron and zinc content and other physico-chemical properties of Inceptisol under 60 days of incubation study. Among all the treatments, the application poultry manure @ 5 t ha-1 had distinct effect on N, P, and K content in soil, followed by application of press mud compost @ 5 t ha-1 which had a significant effect on soil properties under 60 days incubation study.
