The present study examines the chemical composition and morphology of raw and acid-digested pond ash samples that were collected from four ash ponds of the Fertilizer Corporation of India Limited, Sindri unit, Jharkhand, India. Scanning electron microscopy and energy dispersive X-ray spectroscopy were used to analyse the four pond ash samples. The aim of the study was to characterize the pond ash samples in order to assess their utilization based on morphological characteristics. Besides, loss-on-ignition and leaching studies (both with distilled water and under acidic medium conditions) were also conducted to understand the mobility of various elements in the leachates. The information provided herein would be useful to clearly understand the difference in the chemical composition and morphology of the raw and acid digested pond ash samples.Keywords

In this study, the effect of extractive content on fuel properties of selected woody and non-woody biomass samples has been evaluated. The results show significant variation in the amount of extractives (15–70%) present in different biomass samples. There is significant decrease in ash content, fixed carbon content and calorific value in extractive-free samples. The elemental carbon reduces after extraction in woody biomass. There is no specific trend observed in the reduction of elemental carbon with removal of extractives in non-woody samples. In extractive-free samples, ash content decreases by 2–60%, fixed carbon content by 7–24% and calorific value by 1–17%. In conclusion, fuel properties of unextracted biomass are found to be better than extracted biomass.Keywords

Remote sensing and GIS play an important role in wildlife species conservation through their applicability to study spatial distribution, landscape pattern and also factors that affect the distribution, density and movement of wild fauna. The present study deals with the distribution of blackbuck (Antilope cervicapra) in Nahargarh Wildlife Sanctuary, Haryana, India, and to determine their habitat suitability which is shrinking due to the spread of settlements (urban and rural). For habitat suitability analysis of blackbuck, data from WorldClim, 19 bioclimatic variable layers such as temperature, humidity, precipitation, etc. were utilized to calculate the maximum entropy using MaxEnt version 3.2. Satellite data from Landsat 8 were used to generate land use and land cover for analysing habitat suitability. An area of 330.71 ha was found to be suitable for blackbuck habitat within the 10 km buffer area, against the present area of 28.32 ha. The growth of Prosopis juliflora which causes damage to the skin of blackbuck during movement was found to be another factor responsible for confining its niche within the Sanctuary. The present study will help in the effective safeguarding of blackbuck species by the Wildlife Wing of the Haryana Forest Department.Keywords
