A higher percentage of base saturation (BS) in soil is commonly associated with increased fertility. This is because base saturation refers to the proportion of the soil cation exchange capacity that is occupied by base cations, such as calcium, magnesium, potassium, and sodium, which are critical nutrients for plant growth. When a soil has a high percentage of these nutrients available, it generally indicates a greater capacity to supply essential elements to plants, resulting in better plant health and productivity.

In contrast, soils with low base saturation often have higher concentrations of acidic cations (like hydrogen and aluminum), which can be detrimental to plant health and indicate lower fertility. Therefore, soils with a high percentage of base saturation are typically more fertile and able to support robust plant growth, confirming that the relationship between base saturation and soil fertility is a key principle in soil science.
