ABSTRACT

Deforestation affects the soil quality and health by means of various clearing operations, more intense exposure of the soil to weather influences, change in quality and quantity of organic matter input. Present study was undertaken to investigate the changes in soil physical properties due to deforestation, various lands clearing and subsequent land use practices in and around the Nongkhyllem Wildlife Sanctuary, Meghalaya. The sanctuary lies between 25掳45' - 26掳00' N latitude and 91掳45' 92掳00' E longitude. Soils from two depth (0 -15 cm, 15- 30 cm) were collected during 2018-19 from 15 selected places of three sites (Site 1 was un-disturbed, Site 2 semi-disturbed and Site 3 disturbed). Samples were analyzed with standard methodologies. Texture of the soil is dominant by the sand content and contained more than 50% of the soil as revealed by the particle size analysis. The sand percentage was found to be lowest in the deep forest 84.76% followed by semi disturbed area 86.1%, then highest in deforested area 86.26%. Soil particle density in the deep forest in both the depths (0-15 cm and 15-30cm) were found to be highest as compared to the other two sites, viz., semi-disturbed site or deforested area. The soil bulk density of deep forest was found to be the lowest among the three and the deforested or the disturbed area was found to be the highest. As deforestation increased Soil moisture has reduced, bulk density increased, soil particle density decreased clay decreased and sand percentage increased. Simple correlations among soil physical properties indicate the possible reasons for changes in these properties following soil removal and subsequent deforestation.
