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.

Soil Amendments

December 9, 2019
Soil amendments are any materials that when added to soil will improve its properties and processes. Amendments such as lime, gypsum, manure, or biochar can provide many benefits to production systems by improving soil chemical, physical, and biological properties. Some examples of production benefits from amendments include raising pH, adding nutrients, increasing soil organic matter, mitigating salt-affected soils, and improving soil water storage.

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.
