Nitrogen (N) fertilization is a costly operation for most row crop producers. Consequently, it is important to implement best management practices (BMP) available for N fertilizer application in order to be profitable. The problem with N fertilizers is their potential to be lost through different N loss pathways: ammonia volatilization, denitrification, and leaching. Spring of 2020 has been generally wet and if this weather pattern continues, farmers should have no problem receiving incorporating rain, minimizing risk for ammonia volatilization from surface-applied at planting N. In TN, most row crop producers split-apply N, with the majority of N fertilizer applied as a sidedress which is closer to the period of high N demand. Since a large portion of N is applied as sidedress, there is the greatest risk for N loss depending on management practice as well as soil and environmental conditions. Continued wet weather might support the use of nitrification inhibitor type products in wetter soils. This blog addresses N stabilizers as a tool to minimize the risk of N loss and ensure that N is available for crops during the period of high demand. Continue reading

Tennessee held the Top Bean soybean yield contest in 2019, as a collaboration between UT Extension and the Tennessee Soybean Promotion Council. Dry, hot weather in September and excess rains in October and November, created some yield challenges for soybean producers who planted late, but yields for early planted beans were good to excellent. Most higher yield entries were from early (late April or early May) planted soybeans planted on narrow rows.
For the contest, Tennessee was divided into five districts with first and second-place winners in each district. The district fist-place winners automatically competed for Top Bean state yield champion in irrigated and nonirrigated production. Congratulations to Mr. Brad Burks (Lauderdale county) who is the 2019 state winner for irrigated soybean production with 100.2 bushels/acre, and to Mr. Eric Reed (Lincoln county) who is the state winner for nonirrigated soybean production with 89.2 bushels/acre. All district and state winners will receive additional recognition at their local Grain Conferences in February.

While the majority of soybeans are harvested without the benefit of a harvest aid, there are a few situations where they make sense. Using the right product in the right field at the right timing is key to achieving enhanced dry down without impacting seed quality. Continue reading
As May planted soybeans are approaching full seed, I have received several calls about terminating irrigation. Since this has been a hotter year than the past few years, there is some concern that if water is shut off too early, we may give up some yield. Continue reading
