Cation Exchange
Not all soils are created equal. Chemistry helps agriculture succeed in a variety of environments. This video explains how soils (often negatively charged) interact with nutrients (often positively charged) through cation exchange. The cation exchange capacity (CEC) of a soil determines how frequently and in what doses it should receive fertilizer.
