This may lead to change in physico-chemical properties of soil, and subsequently loss of productivity making the soil vulnerable to erosion. For present investigation, a total of three forest patches representing undisturbed (UD), moderately disturbed (MD) and highly disturbed (HD) sites were selected within the Pachhunga University College campus, Aizawl, Mizoram.  The soil samples were analyzed seasonally  (post-monsoon, pre-monsoon and monsoon seasons), for soil temperature, soil moisture content, water holding capacity, bulk density, pH, organic carbon, NPK. The soil temperature was increased with increase in degree of disturbance, showing direct influence of ambient temperature on seasonality. The soil moisture content and water holding capacity decreased from undisturbed to highly disturbed site. On the contrary, bulk density was reported to be high at disturbed site. The soil was acidic in nature irrespective of sites and seasons. There was a sharp decline in soil organic carbon, and NPK from undisturbed to highly disturbed stand, and highest values were recorded during post-monsoon season and lowest during monsoon season. The higher values during post-monsoon season may be attributed due to accelerated rate of decomposition of litter.<#LINE#>FAO (2002).@Tropical secondary forest management in Africa: Reality and perspectives.

Ramakrishnan College of Technology, Tiruchirappalli – 621112, Tamilnadu, India<#LINE#>22/3/2017<#LINE#>20/5/2017<#LINE#>The present study is targeted to determine the Ground water quality index (WQI) of Pennagaram Block, Dharmapuri District, Tamilnadu, India. The WQI categorized by gathering groundwater samples during the month of September 2015 and analyzed for physicochemical parameters. The following parameters have been measured for manipulative the Water Quality Index such as pH, Electrical conductivity, Total Dissolved solids, Total Alkalinity, Total Hardness, Calcium, Magnesium, Chloride, Nitrate, Sulphate, Fluoride, Dissolved oxygen. The outcomes of water quality index have been have been utilized for better comprehension for the present water nature of the review region. And also it has been used to suggest the models for recognizing the water nature of the review area region. This analysis exposes that the quality of groundwater of the study area region needs a certain level of management earlier consumption, and it requires an alternate source of water or threatened from the dangers of groundwater pollution.<#LINE#>Asonye C.C., Okolie N.P., Okenwa E.E. and Wuanyanwu U.G.
