Groundwater

How nitrogen moves and is changed in the soil is important to help protect Nebraska's groundwater from contamination. However, these changes are not fully understood. To help understand these processes, a research team led by Dr. Arindam Malakar, scientist and research assistant professor in the School of Natural Resources and the Nebraska Water Center part of the Daugherty Water for Food Global Institute at the University of Nebraska-Lincoln, has begun a statewide study to uncover nitrogen transformation in the vadose zone.

Scheduling the last few irrigations of the season deserves extra attention because the goal is not only to focus on keeping the crop wet enough to produce optimal yields, but also on using up stored soil water. Leaving the field a little drier at the end of the season will save irrigation costs, decrease leaching losses, improve soil conditions for harvest traffic, and save water for future years. Growers also don't want to miss out on capturing off-season precipitation.

It’s that time of year again and I’m here to help you stay on track for that New Year’s resolution to “Manure Better”. That wasn’t your resolution? I’m sorry, but it would be a great resolution and an achievable one at that, so add it to your list. My New Year’s resolution is to help crop farmers “Manure Better”. The annual land application (manure) training events are coming up soon and may be just the ticket to “help me, help you”.

Nitrogen is an essential plant nutrient but increasingly found in our water. Here is a brief history:

This year's 4Rs Field Day will feature a demonstration on UNL's newly developed web-based N tool, designed to increase efficiency of nitrogen use, as well as ease of record-keeping.

Nebraska Extension will host a Nitrogen Sources and Water Quality Field Day on August 13, 2024, from 9:30 a.m. to 2:30 p.m., at the Haskell Ag Lab near Concord, NE.
