Soil rich in organic matter is apt for the growth of plants as it provides them with nutrients essential for their growth and nourishment. Apart from that, it also affects the soil structure and mineralogy and ultimately the soil properties. Based on same purpose, this study was carried out to investigate the effect of organic matter (Vermi-compost) on the compaction characteristics of Karewa soils. In thus study, three soil samples were taken from three sites and characterised as “CL” (clayey soil with low plasticity). Proctor tests of different compaction energies (viz., Standard Proctor, Modified Proctor and Reduced Standard Proctor) were conducted on the samples with and without Vermi-compost. The percentages of Vermi-compost by dry weight of soil was taken as 3%, 6%, 9% and 12% and mixed with soil thoroughly before each Proctor test. The maximum dry density and optimum moisture content of the Karewa soil corresponding to each Vermi-compost percentage was determined in Geo-Technical Laboratory of NIT Srinagar. Proctor results indicate that on introduction of Vermi-compost to the Karewa soils, maximum dry density decreases and Optimum moisture content increases with the increase in Vermi-compost percentage upto 12% and beyond that the mixture became unworkable. An empirical model relating maximum dry density and optimum moisture content with organic matter content was also established on the basis of the acquired Proctor test results.
