Soil Base Saturation | Jon Skinner speaks of Ca, K, & Mg that occupy these exchange sites

This topic can be fun as it helps us find a simple way to easily assess our fertility levels on the nutrients that are held by the soil's exchange sites. Jon speaks about the value of finding a common sense assessment of what ratios are optimum vs good enough vs a problem in soil fertility. Cation exchange capacity is part of the caculation of figuring the base saturation size, AKA how many exchange sites are available vs how many cations occupy the sites in the soil colloid. Beck's Hybrids Regional Agronomy Manager for Iowa and Illinois help us understand key areas for more clarity in soil health and care on our farms and fields.
