Soil tests can reveal not only what types of nutrients your soil contains, but how those nutrients affect each other and, in turn, your soil. The cation exchange capacity and cation base saturation are two items found in a soil test, and, if you know how to interpret them, they can help you to understand the complex properties of your soil.

Calculating Cation Exchange Capacity - Midwest Labs

The Basic Cation Saturation Ratio System

The basic cation saturation ratio system, which attempts to balance the amount of Ca, Mg, and K in soils according to certain ratios, grew out of work in the 1940s and 1950s by Firman Bear and his coworkers in New Jersey and later by William Albrecht in Missouri.
