Depth-Wise Distribution of Soil Chemical Properties, Micro-nutrients Status, and Bacterial Population under Quercus leucotrichophora and Shorea robusta Forest of Chakrata and Thano Region of Uttarakhand

Forest trees have an appreciable demand for nutrients as they have longer rotation than crops and this is easily replenished by the constant release of nutrients resulting from weathering under favorable conditions in the soils developed from parent material rich in nutrient-bearing minerals. A study was undertaken to assess the chemical properties, micro-nutrient status, and bacterial population; two sites were taken for the collection of soil samples: the oak forest of Chakrata and the Sal forest of Thano. Soils were drawn at three depths viz. 0-30 cm, 30-60 cm, 60-90 cm. All soil parameters examined at three depths viz. 0-30 cm, 30-60 cm, 60-90 cm. Oak (Quercus Leucotrichophora) forests have higher microbial activity than Sal forests. The soil in both the studied areas was rich in nutrients, where, the maximum mean standard deviation values of pH (6.85), soil organic carbon (5.9 %), available nitrogen (0.04 %) reported in the Oak forest of Chakrata, and available phosphorus were almost similar in both forest regions. Oak forests have higher organic carbon, water-holding capacity, and nutrient availability compared to Sal forests. However, it is concluded that, for better conditions of these forests for soil and carbon-storing potential, the forest needs good management practices, especially in community forest areas to avoid illegal felling, impact of fire, and over-exploitation of fuel and fodder. Good management practices would help mitigate the impact of climate change and sustainable outcomes of the resources for the community's benefit.
