Answer 1

Answer 2

• As we know that CEC is the measurement of the amount of positively-charged ions (cations) which can be bound by the weight of soil.
• And soils with large CEC are typically high in clay minerals and soil organic matter which have a lot of negative charges.
• And due to the variable charges on the organic matter a soil's CEC increases with pH.
• As low CEC means that fewer nutrients can be held by the soil, implying a need for more frequent nutrient additions.
