Q&As on Nitrogen Investment in Corn This Year
March 31, 2021
Most of Nebraska was drier than normal in 2020, which means a potential increase of residual nitrate-N. As such, producers may need to reduce fertilizer-N rates for 2021 — but how much is enough?
Planning 2021 Fertilizer-N Application Following a Dry 2020
October 6, 2020
Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?
New NebGuide: Soil Microbiology in Nebraska
July 15, 2020
Soil microbiology is a universal and essential component of agricultural soils. This NebGuide provides basic information of soil microbiology, microbial functions, microbial enhancement, and microbial assessment.
Fertilizer-nitrogen Injury
May 22, 2020
Nitrogen (N) is the most limiting nutrient in corn. However, there is risk of crop injury with band application of fertilizer-N.
Tips for In-season Nitrogen Management in Corn
April 29, 2020
This spring conditions are good for pre-plant fertilizer, but there are still considerations that justify shifting more nitrogen application to in-season versus pre-plant.
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.
