What is a water soluble soil nutrient analysis test? Why is it important?
A regular soil test or chemical extraction of the soil determines the total quantity of nutrients in the soil. These nutrients may not all be readily available to the turfgrass. The water soluble soil nutrient analysis test or water extraction of the soil determines that portion of the total nutrients that are soluble or readily available to the turf. In addition, the chlorides, bicarbonates, and soluble nitrogen levels can also be measured with this test.
