WebCation-exchange capacity (CEC) is a measure of how many cations can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules (cations), but allow these to exchange with other positively charged particles in the surrounding soil water. This is one of the ways that solid … WebAluminum is one of the most abundant elements in soil. Natural acidification processes result in increasing solubility of aluminum and, as soils become moderately acidic (pH < 5.5), aluminum begins to appear as the exchangeable cation which dominates in the lower mineral horizons.

WebThe “ideal” soil pH is close to neutral, and neutral soils are considered to fall within a range from a slightly acidic pH of 6.5 to slightly alkaline pH of 7.5.
