dc.description.abstractABSTRACT A laboratory incubation experiment entitled “Influence of organic amendments on chemical and microbiological properties of soils of district Solan (Himachal Pradesh)” was conducted in the Department of Soil Science and Water Management, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (H. P.) during 2014. Eight types of soil samples were collected from selected areas of Solan district on the basis of soil texture from the depth of 0-15 cm and treated with three organic amendments (Farm yard manure, vermicompost and city waste compost) and one control. The experiment was laid out in completely randomized design (factorial) with three replications. The studies were undertaken to investigate the effect of organic amendments on different chemical and microbiological properties of different soils. Soil sampling was done from each treatment at an interval of 30, 60, 90 and 120 daysof incubation for determination of all the parameters. Available macro and micronutrients, exchangeable cations, cation exchange capacity, water soluble calcium, potassium and microbial count were increased significantly, whereas exchangeable sodium, water soluble sodium and water soluble magnesium were having no significant effect while on addition of amendments. Organic carbon and microbial biomass carbon of different soils decreased with increase in time interval. Farm yard manure and vermicompost improved soil properties more effectively compared to city waste compost. The increase was more pronounced during first two months.en_US
