Cation exchange capacity (CEC), as an important indicator for soil quality, represents soil's ability to hold positively charged ions. We attempted to predict CEC using different statistical methods including monotone analysis of variance (MONANOVA), artificial neural networks (ANNs), principal ...
As soil cation exchange capacity (CEC) is a vital indicator of soil quality and pollutant sequestration capacity, a study wasconducted to evaluate cokriging of CEC with the principal components derived from soil physico-chemical properties. InQingdao, China, 107 soil samples were collected. Soil CEC...
Cation Exchange Capacity (CEC) is a general indicator of soil storage capacity for available positively-charged plant nutrients such as calcium, magnesium, potassium and sodium. In some instances, this method appears to overestimate exchangeable magnesium in some ...
Before the onset of the experiment, there were stemflow - induced gradients in the saturation of exchange sites with K+, H+ and Na+ that were larger near the stems, while the pHKCl, the cation - exchange capacity, and the saturation with Ca2+, Mg2+ and Mn2+ were smaller. After 8 yr...
Cation Exchange Capacity: The nutrients, herbicides, and other constituents of soil are generally positively charged whereas the soil particles are generally negatively charged. A quantified measure of the ability of soil particles to attract the positively-charged ions is called cation ex...
A slight modification to Bascomb's procedure for determining cation exchange capacity makes it applicable to gypsic soils even when the gypsum content is as high as seventy percent. The modification involves a second titration of the final extract made specifically for calcium and which is necessary...
Cation exchange capacity (CEC) is one of the most important chemical characteristics which influences soil quality from different aspects. At the same time, CEC is an input parameter of many computer models being applied in soil science and agriculture. Methods of CEC determination are always time...
The cation exchange capacity, (CEC) of soils depends on the amount and composition not only, of clay minerals but also of soil organic matter (SOM). While the CEC of soil clay minerals; has been intensively studied, little is known about the CEC of organic matter (OM) fractions, in ...
