Fall fertilizer applications offer cost savings and time management benefits, but also may contribute to increased soil nitrate-N leaching. With Nebraska's high soil moisture levels, consider these suggestions when applying nitrogen this fall.
The Nebraska Extension Circular, Nutrient Management Suggestions for Corn (EC117), has been updated to account for residual soil nitrate-N and provide an alternative for determining fertilizer-P rates.
Under the 2019 Nebraska Hemp Farming Act, the Nebraska Department of Agriculture (NDA) may license persons to cultivate, handle or process hemp under an expanded NDA hemp pilot program. Individuals may apply to NDA by 5 p.m. Friday, June 28 for hemp cultivation licenses under the pilot program.
Spring weather has complicated nitrogen management this year, making in-season nitrogen application necessary in many fields. You can estimate N needs with the Late Spring Soil Nitrate Test or by use of crop canopy reflectance sensing, both of which are addressed here.
A multi-year study of organic N used in Nebraska crop production validated sensor guided in-season N application as a means to efficiently use the N available from manure and other organic materials. See what benefits they found, as well as considerations for use.
This article addresses nitrogen application options for corn and availability of P and K from land-applied grain and fodder damaged by flooding. It supplements the previous article, Nutrient Management Issues for 2019.
