Tóm tắt

Assessment of soil quality is essential for providing sustainable management strategies in an anthropogenically disturbed forest. The study was conducted in coal mine disturbed forest (CMDF) and undisturbed community forest (UDCF) at the Northern tropical semi-deciduous forest of Nagaland to investigate soil physico-chemical properties and SQI using principal component analysis (PCA). Comparative soil physico-chemical analysis shows CMDF soil has acidic pH (3.58 ± 0.09), reduced organic carbon (1.21 ± 0.03) and low available N (83.47 ± 8.73), available K (161.28 ± 6.37) and total N (0.87 ± 0.05). In both the methods, UDCF presented higher soil quality index with SQIa (UDCF = 1.97, CMDF = 1.61) and SQIw (UDCF = 0.98, CMDF = 0.68). The result exhibits that anthropogenic activities such as deforestation and coal mining in tropical forest can deteriorate soil quality and hamper the rejuvenating soil properties.
