The CEC Mechanism is the soil’s Cation Exchange Capacity.

CEC is a measure of how many nutrients a soil can supply to crop, or in other words, how fertile is the
soil? The higher the CEC, the more fertile the soil which leads directly to the number of times
crops can be grown and harvested. Research is also indicating that CEC indicates the ability of soil to retain water! The most productive soils in the world have a CEC of 20 or above. A CEC of less than 10 may only produce a meager crop.

Elemite has a CEC of 35!

Really? Yep!
