The present study evaluated the effects of long-term tillage operation on soil physical properties and nutrient dynamics on surface soil. The soil samples were collected at 0 to 15cm soil depth profiles in the year of 2016 and 2017 from following treatment (T1) Conventional tillage, (T2) Conventional tillage with seeding by bullock drawn, (T3) Zero till seeding with bullock drawn, (T4) Conservation tillage seeding with country plough and (T5) Utera cropping (T5). The samples were analyzed for physical properties, Soil organic carbon and macronutrient. The statistical analysis was made in SAS 9.3 DMRT test was employed to compare the mean of estimated soil nutrient dynamics. Coupled with other physic chemical parameters of soil affected by different tillage treatment. The effect of tillage management was found significant on most of soil physic chemical parameters Zero tillage had highest amount of available N, P, K and S over other tillage treatments. The highest SOC was found in conservation tillage at par Zero tillage. The lowest SOC was recorded in Utera cropping. This study showed that zero tillage enhances physical environment of soil as well as availability of nutrients that may result sustainable soil health and crop yield.
