Cation Exchange Capacity (CEC)
greater water holding capacity than low CEC (sandy) soils. o Low CEC soils are more likely to develop potassium and magnesium (and other cation) deficiencies, while high CEC soils are less susceptible to leaching losses of these cations. So, for sandy soils, a large one-time addition of cations e.g…

When plants are young and small, nutrient need is low. As plants enlarge and start to grow rapidly, nutrient needs increase dramatically. Competency Area 2: Basic Concepts of Soil Fertility 7.

When reduced-till systems are combined with residue management and manure management, soil organic carbon can increase over time.

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.
