Soil texturedescribes its relative fineness or coarseness, specifically in terms of sand, silt and clay. This composition determines much about a soil — for example, how well it holds water, its Cation Exchange Capacity (CEC) level and its buffering capacity. Texture is an important characteristi...
If there is a concentration of one particular cation in the soil water, those cations will force other cations off the colloid and take their place.The stronger the colloid's negative charge, the greater its capacity to hold and exchange cations, hence the term cation exchange capacity (CEC)....
CEC is a measureof the capacity of soils to retain positively charged nutrients. In soils, there are negative charges associated with clay-sized particles and soil organic matter.GEORGE REHM... G Rehm - 《Corn & Soybean Digest》 被引量: 0发表: 2009年...

Soil organic matter (SOM) represents one of the largest reservoirs of carbon on the global scale. Thus, the temperature sensitivity of bulk SOM and of diff
These hydrocarbons (CxHy) can be made in (1) unlimited quantities from natural sources of carbon dioxide (such as from air or ocean) and (2) large quantities from cellulosic biomass. In both cases, there is no net addition of carbon dioxide to the atmosphere. Carbon dioxide is removed ...

The tsetse fly (Glossina genus) is the main vector of African trypanosomes, which are protozoan parasites that cause human and animal African trypanosomiases in Sub-Saharan Africa. In the frame of the IAEA/FAO program ‘Enhancing Vector Refractoriness to
