Assessment of soil quality in texturally different and salt-affected soils of trans-gangetic plains of India
The intensive cultivation and multi nutrient deficiencies in trans-gangetic plains of India are affecting productivity potential of coarse textured, fine textured and salt affected soils which make it essential to appraise the novel soil quality indicators. The present study was carried out to analyze the variations in 36 bulk soil samples in texturally different and salt-affected soils under rice–wheat cropping system. Among soil properties, the average value of electrical conductivity (dS m−1), soil organic carbon (%), exchangeable sodium (%), available nitrogen (kg ha−1), available phosphorus (kg ha−1), available potassium (kg ha−1), available sulphur (mg kg−1) and DTPA-iron, manganese, zinc and copper (mg kg−1) were 1.58, 0.67, 10.7, 208, 85.4, 502, 32.3, 15.5, 5.29, 2.88, and 1.38, respectively. In soil quality index, 6 indicators in coarse textured, 5 in fine textured and 6 in salt affected soils explained the total variance of 90.5, 90.2and 93.7%, respectively. In overall, 6 indicators i.e. soil organic carbon, sulphur, carbonate + bicarbonate, soil pH, calcium + magnesium and manganese were identified as novel soil quality indicators under rice wheat cropping system of trans-gangetic plains of India.
期刊介绍：
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
