Effects of Straw Incorporation on Soil Organic Matter and Soil Water-Stable Aggregates Content in Semiarid Regions of Northwest China
The soil degradation caused by conventional tillage in rain-fed areas of northwest China is known to reduce the water-use efficiency and crop yield because of reduced soil porosity and the decreased availability of soil water and nutrients. Thus, we investigated the effects of straw incorporation on soil aggregates with different straw incorporation rates in semiarid areas of southern Ningxia f...
متن کاملChange of Soil Carbon Fractions and Water-Stable Aggregates in a Forest Ecosystem Succession in South China
In order to evaluate the dynamics of carbon storage during forest succession and explore the significance of water relations and soil stability in forest environments, a study was conducted in 2011. This study investigated the dynamics of soil organic carbon (SOC) fractions and its protection through aggregation along the successional forests. An experiment in South China examined pine forest (...
متن کاملRemoval of arsenic from drinking water and soil bioremediation
Various countries in America have reported the existence of people suffering chronic exposure to levels of arsenic in drinking water that are higher than those envisaged in international standards. This is the case in Canada, the United States, Chile, Peru, Bolivia, Mexico, El Salvador and Nicaragua. Some of these countries have solved, either fully or in part, the problem of technology availab...
متن کاملSafer sips: removing arsenic from drinking water.
U.S. researchers are developing technologies that may someday protect millions of people worldwide whose drinking water is tainted with arsenic. Arsenic is released into water from soil and rock erosion, and is also a by-product of industrial processes including semiconductor manufacturing, petroleum refining, and mining and smelting operations.
متن کاملWarming impacts on carbon, nitrogen and phosphorus distribution in soil water-stable aggregates
Guan S., An N., Liu J.H., Zong N., He Y.T., Shi P.L., Zhang J.J., He N.P. (2018): Warming impacts on carbon, nitrogen and phosphorus distribution in soil water-stable aggregates. Plant Soil Environ., 64: 64–69. A five-year (2010–2015) field experiment was conducted to investigate warming impacts on organic carbon (OC), total nitrogen (TN) and total phosphorus (TP) contents and their ratios in b...
