Soil Science Review: Cation Exchange Capacity
WebThe high values of CEC for organic soils is explained by the high adsorptive capacity of SOM, particularly at pH above 5 [51]. Two types of surface charges categories exist: (1) the permanent charges that are not affected by changes in soil–solution conditions and nature of free ionic species; and (2) the variable charges, which are affected by changes in … WebHigh-clay or high organic-matter soils have relatively high CEC. Cation exchange capacity can give an indication of soil texture and is often an indicator of general soil fertility . Furthermore, base saturation is the percentage of the CEC occupied by what are called “basic” cations, as opposed to cations of an acidic nature. crystal meth strafen

WebSoil base saturation or percent base saturation is the measurement of the proportion of soil CEC (negatively charges exchange sites) that is occupied (adsorbed) by the basic cations such as Ca 2+, Mg 2+, Na + and K +. The unit for measuring base saturation is percent. An alkaline soil pH of 7.0 or more is indicative of a high base saturation ... WebIt is a measure of the acidity or alkalinity on a 1-14 scale with 7 being neutral. The H stands for the Hydrogen ion and the scale measures the ability of the soil to donate H to the … Web4 de mar. de 2024 · The units are numerically equivalent, so a soil with CEC 20 cmol c /kg is equal to 20 meq/100 g. Soils with high CEC are generally more fertile and can provide plants with more nutrients and water. A soil with high CEC (>25 cmol c /kg) can hold many cation nutrients and likely contains a high amount of clay and/or organic matter. crystal meth substanz
