Abstract
Present study was undertaken to investigate the role of tillage on soil physical properties of different agroecosystems in Lunglei district situated in the south-central part of Mizoram state, northeastern India. Lunglei is located at 22.88oN 92.73oE. Detailed study was conducted in selected land use of the district such as homegarden or agro-forestry, forest and paddy field. Soil samples were then bagged in a polythene bag air-tight and then brought to the laboratory to analyze their soil characteristics with the standard methodologies. It was found that conventional tillage practices cause change in soil structure by modifying soil bulk density, soil moisture content and other characters. Conventional tillage is responsible for the finer and loose-setting soil structure while conservation and no-tillage methods leave the soil structure intact. Therefore, at present there is a considerable concentration and emphasis on the transform from extreme tillage to conservation and no-tillage methods for soil conservation.
