Manure Nitrogen Use for Increased Profit and Environmental Protection

February 5, 2020
Land application of manure and other organic materials supplies much N to Nebraska’s crop production. In contrast to most other nutrients applied in organic materials, the availability of manure-N and its fertilizer-N substitution value is not well-predicted.

$1.2 Million Grant to Help Corn and Wheat Growers Manage Nitrogen Fertilizer Application

January 13, 2020
Corn and wheat growers across Nebraska will be able to gain hands-on experience with cutting-edge technologies that will allow them to more precisely identify the amount of nitrogen fertilizer their crops need, while preventing excess nitrates from ending up in Nebraska’s water supply.

Agronomic Management for Reduced Nitrate Leaching

January 7, 2020
The leaching of nitrate to groundwater and the increasing occurrence of groundwater with excessive nitrate levels for human consumption is a major concern in Nebraska. The amount of leached NO3- depends on soil NO3- concentration at different soil depth layers and the quantity of water movement downward through these soil layers to beyond the root zone.

Long-Term Study Suggests Management Adaptations for Weather Extremes

July 16, 2019
From droughts to flooding, extreme hydrological phenomena are the costliest hazards in rainfed agriculture. A recent journal article explores how a long-term tillage study in northeast Nebraska can offer insights on successfully adapting to future climate changes by adjusting specific management practices.

In-season Nitrogen Management for Corn in 2019

June 12, 2019
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.
