Cation Exchange Capacity (CEC)
the soil pH, the CEC associated with soil organic matter is called pH-dependent CEC. This means that the actual CEC of the soil will depend on the pH of the soil. Given the same amount and type of organic matter, a neutral soil (pH ~7) will have a higher CEC than a soil with e.g. pH 5, or in other words, the CEC of a soil with pH-dependent ...

Soil Texture - Cornell University
nmsp.cals.cornell.eduTexture should not be confused with structure, which refers to how soil particles are aggregated together. It is possible to improve soil structure via best management practices such as reduced tillage. However, it is very impractical (expensive) and thus ill-advised to modify a soil’s texture.
