摘要

The present investigation entitled "Seasonal Micro-climatic Variations in Physical and Chemical Characteristics of the Soil on different forest ecosystems under mid hills conditions of Himachal Pradesh" was carried out during winter and summer seasonsof the year 2015-16 under the Department of Environmental Science, College of Forestry, Dr. Y.S. Pamnar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. A comparison of below forest canopy and open sites was earned out for abiotic and biotic factors under five forest ecosystems (Chir Pine Forest, Mixed Forest, Ban Oak Forest, Agriculture Field and Bare Area) and analysed the physico-chemical properties of soil. The collected soil samples from the forest ecosystem were analysed for soil moisture, bulk density, pH, electrical conductivity, soil organic carbon and available NPK. The results showed that the higher percent of moisture was found in forest ecosystem as compared to open area and having difference of (8.0-15.2%) and found higher in oak forest. The forest ecosystem indicate that the soil of oak forest was slightly acidic to pine forest. The forest ecosystem wise soil organic carbon and available K status followed the order of ban oak forest > mixed forest >chir pine forest > agriculture field > bare area. However the status of available N and P followed the order of agriculture field > ban oak forest > mixed forest >chir pine forest > bare area. Although the bulk density was observed highest in bare area (1.41 g cm"3)and lowest was reported under ban oak forest (1.27g cm3). Based on our results, we conclude that Ban oak forest generally had a greater moderating effect during both the season and are rich in nutrient availability as compared to chir pine and mixed forest and directly influenced the soil physico-chemical properties, nutrient cycling, microbial biomass and therefore, affects the natural regeneration process of native species.
