It is cover crop burndown time. There is no one size fits all recommendation for cover crop control.  It really depends on the environment and the cover crop species in the field.  With rain predicted over the next few days, one should be mindful that cover crop burndown can be tricky during periods of saturated soil conditions. This is particularly true with systemic herbicides where translocation of those herbicides to growing points can become limited. Continue reading

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.
