Agronomic Services - Soil Testing


Soil testing evaluates soil fertility through extraction of nutrients (excluding nitrogen) essential in plant nutrition. Amounts of plant available nutrients are converted to an index from which their sufficiency or toxicity can be assessed, and site-specific fertilizer recommendations are determined. Soil acidity and pH are also measured to evaluate liming needs. Soil testing is used in nutrient management strategies to optimize crop yields, profitability and protect natural resources from excessive nutrient application.  Note that the Agronomic Division does not test for contaminants in soil.
