Soil pH and Nutrients: Everything Is Local

Abstract Developed more than 80 years ago, the soil pH and nutrient diagram offers a quick reference that growers can use to gauge soil fertility and plant nutrition. At first glance, the relationship between soil pH and nutrient availability makes sense. Soil pH influences the solubility, concentration, ionic form, adsorption, and mobility of important plant nutrients. But this simple diagram hides the complexity of this relationship.
