Converting Between Mehlich 1 and 3 Soil Test Values for West Tennessee Soils

Author:  Comments Off on Converting Between Mehlich 1 and 3 Soil Test Values for West Tennessee Soils

Most growers may receive soil test results from laboratories that utilizes Mehlich 3 soil test extraction method. However, The University of Tennessee gives fertilizer recommendations based on the Mehlich 1 extractant. This makes it difficult for growers to take advantage of The University of Tennessee fertilizer recommendations.
