WebIncreasing your soil's (CEC) can be achieved through soil pH adjustment and soil amendments. CEC has shown to be correlated to the alkalinity of a soil. As the pH of soil increases, so too does the CEC. This occurs because as the pH increases there are more negatively charged stations on the colloids to hold more cations.
WebOne of the benefits of liming acid soils is increasing soil CEC. As the pH increases, so does the CEC of organic matter as well as some clay minerals. As hydrogen (H +) on humus is neutralized by liming, the site where it was attached now has a negative charge and can hold Ca ++, Mg ++, K +, etc. Many soil testing labs will run CEC if asked. Web19 okt. 2016 · Clay and silt particles have negatively charged sites which enable them adsorb and hold on to cations. Sandy soils have CEC between 1-5meq/100g.4 Clay soils such as smectite and illite can have CECs between 25-100meq/100g.3,4 Increasing the clay content of a sandy soil will help increase its CEC.
WebThe important thing to realize is that phosphorus availability can be improved with adjustment of soil pH. Figure 1 shows that the highest phosphorus availability is generally thought to occur between 6.5 and 7.5. Increasing the soil pH with lime to at least 6.2 (for most crops) would result in higher phosphorus availability (Mallarino et al ... http://nmsp.cals.cornell.edu/publications/factsheets/factsheet22.pdf
