Competency Area 2: Basic Concepts of Soil Fertility


Plants take up the majority of their nutrient needs from the soil by utilizing different transport mechanisms. Different characteristics of soils affect their nutrient-holding capacity and which mechanisms work best.

Some macronutrients, particularly nitrogen and phosphorus, cycle between residency in the soil, usage by plants, and air- and water-borne particles. These have important environmental effects, and the actions of these cycles influences crop management.
