Identification of Soil Quality Factors and Indicators for the Loess Plateau of China
Soil quality has been significantly degraded in the Loess Plateau of China by soil erosion. Our objectives were to (i) identify regional-scale soil quality factors (groupings), (ii) select soil attributes within these factors that can be used as indicators of soil quality, and (iii) determine the impact of land use on these soil quality factors and indicators for the Loess Plateau in China. Soi...
متن کاملOptimal Indicators for Microtopography-oriented Soil Quality Assessment in Semiarid Regions of the Loess Plateau, China
This study was aimed to identify optimal indicators for microtopography-oriented soil quality assessment. Twenty-two soil physicochemical and biological parameters were investigated at 93 sampling points in five different microtopographic units in semiarid regions of the Loess Plateau, where the principal functions of eroded agriculture soils are related to productivity and anti-erosion ability...
متن کاملEffects of sewage sludge and its biochar on soybean yield in fine-textured loess soil
Background: The application of biochar as a soil amendment has achieved popularity and has been found to improve considerably soil nutrient status and plant productivity in low fertile soils. Methods: This study used two different methods to apply sewage sludge and sewage sludge biochar with three replicates in a completely randomized block design. The experiment included (1) control, (2) mulc...
متن کاملSoil Quality Indicators
Total organic carbon (TOC) is the carbon (C) stored in soil organic matter (SOM). Organic carbon (OC) enters the soil through the decomposition of plant and animal residues, root exudates, living and dead microorganisms, and soil biota. SOM is the organic fraction of soil exclusive of nondecomposed plant and animal residues. Nevertheless, most analytical methods do not distinguish between decom...
