Anticipated high residual soil nitrate-N levels in Nebraska rainfed crops of dry 2020 may allow reduced N rates for 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?

Nutrient Management Specialist Javed Iqbal analyzes the use of fertilizer stabilizers to mitigate nitrogen fertilizer loss and increase productivity.
Manure application on frozen or snow-covered soil poses a higher risk of nutrient loss through runoff.

A blanket of fresh white snow and icicles hanging from the trees and fences make for beautiful winter photos. They don’t, however, make for beautiful manure application weather.
Anticipated high residual soil nitrate-N levels in NE rainfed crops of dry 2020 can be credited to reduce N rates for 2021

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?

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.
