Soil organic matter as sole indicator of soil degradation.
Soil organic matter (SOM) is known to play vital roles in the maintenance and improvement of many soil properties and processes. These roles, which largely influence soil functions, are a pool of specific contributions of different components of SOM. The soil functions, in turn, normally define the level of soil degradation, viewed as quantifiable temporal changes in a soil that impairs its qua...
متن کاملEffects 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 کاملXiphinema americanum as Affected by Soil Organic Matter and Porosity.
The effects of four soil types, soil porosity, particle size, and organic matter were tested on survival and migration of Xiphinema americanum. Survival and migration were significantly greater in silt loam than in clay loam and silty clay soils. Nematode numbers were significantly greater in softs planted with soybeans than in fallow softs. Nematode survival was greatest at the higher of two p...
متن کاملSoil Organic Matter: Its Fractionation and Role in Soil Structure
An understanding of the form and function of SOM in soil is essential to sustainable crop production. Various methods of SOM fractionation are used to study SOM forms and to gain an understanding of interaction between SOM and aggregate formation. Physical SOM fractionation techniques are based on the concept that SOM associated with particles of various sizes. differs in structure and function...
