WebCation exchange capacity (CEC) is a measure of the total minus charges within the soil that adsorb plant nutrient deionized such like calcium (Ca2+), metal (Mg2+) and potassium (K+). As such, the CEC is a property is a land that describes its capacity toward supply nutrient cations to the soil solution for plant uptake. WebSecondly, use Figure 2 to calculate the water holding capacity of each soil layer in the root zone. For example, 25cm of clay loam with an available water of 1.8mm water per cm of soil, can store 45mm of available water. The water holding capacity of a soil is calculated by summing the capacity of each layer in the root zone.
