Soil Test Interpretation - Waypoint Analytical

CEC will typically be inflated with these soil types. CATION SATURATION Cation saturation refers to the proportion of the CEC occupied by a given cation (an ion with a positive charge such as calcium, magnesium or potassium). The percentage saturation for each of the base cations are commonly within the following ranges:

  Base, Saturation

GUIDE POUR L’INTERPRÉTATION D’UNE ANALYSE DE SOL

Le % de saturation pour chaque base se calcule de la façon suivante : (meq /100 g. sol ÷ CEC) X 100 Or, pour convertir les valeurs de l’analyse en « kg/ha » en valeurs de « meq/100 g. sol », soit les mêmes unités que la CEC, on doit d’abord effectuer les opérations suivantes : K : kg K/ha ÷ 876 = meq K /100 g. sol
