An agronomic soil test extracts a portion of the plant available nutrients contained in a soil sample and results are then classified as low, medium, high or very high based on expected crop response to added crop nutrients, crops grown on soils that test high to very high for a specific nutrient are not likely to respond with a yield increase if that nutrient is applied to the soil. However, soils testing low or medium for that nutrient are likely to show improved yield and quality if that nutrient is applied (provided other nutrients are present in adequate amounts).

Soil testing is a required component of nutrient management plans for many commercial farming operations as well as for purchase of phosphorous containing fertilizers for use on established lawns in some Northeast states.
