Soil Environmental Quality Assessment in Sustainable Rehabilitation of Mine Waste Area: Establishing an Integrated Indicator-based System
Soil environmental quality is the capacity of a soil to function, within ecosystem and land use boundaries, to sustain biological productivity, maintain environmental quality, and promote plant, animal and human health'. In the long-term, vegetative rehabilitation of mining wastes aims at, as far as possible, the proper ecological integration of the reclaimed area into the surrounding landscape...

In order to investigate phenotypic abnormality in Khorram-rud River in Lorestan province in Iran, 1982 specimens including 13 species were caught. For this purpose, 8 sites were chosen on Khorram-rud River in Khorramabad city from 10 Km upstream to 10 km downstream of the city. Fish were caught using a cast net. Most of the sampled fish were returned to the river if there were no phenotypic abn...
متن کاملSoil Quality Assessment: Past, Present and Future
Soil quality assessment may be one of the most contentious topics ever debated by the soil science community. Our objective is to examine the history, present status, and potential for using soil quality assessment as a tool to monitor soil physical, chemical, and biological effects of management decisions that may affect soil and water resources. Differences between inherent and dynamic soil q...
متن کاملEffect of long term no-till and conventional tillage practices on soil quality
Management systems influence soil quality over time. A randomized block design in 2 (tillage system) 3 (crop rotation) factorial arrangement was laid-out to evaluate the impact of tillage and crop rotation (2002–2007) on soil quality. Conventional tillage and No-till were factored into continuous corn, corn–soybean, and corn–soybean–wheat–Cowpea systems. Ten soil cores were collected at 0–7.5, ...

To investigate the degree of forest degradation and the effect of land use change on selected soil quality attributes in loess-derived landforms, samples were taken from different land uses including forest, rangeland, degradated rangeland and farmland in Pasang watershed located in the Galikesh area of Golestan province (37°16'N, 55°30'E). The annual average temperature and mean precipitation ...
متن کاملBiological indices of soil quality : an ecosystem case study of their use Jennifer
Soil quality indices can help ensure that site productivity and soil function are maintained. Biological indices yield evidence of how a soil functions and interacts with the plants, animals and climate that comprise an ecosystem. Soil scientists can identify and quantify both chemical and biological soil-quality indicators for ecosystems with a single main function, such as agricultural lands ...
