Land Application

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?

The Nebraska Department of Agriculture has released a new feature article on the manure industry in Nebraska. In the article, which is part two of a two-part series, the author highlights the fact that manure is nature's recycling program from the perspectives of crop and animal farmers.

Manure application on frozen or snow-covered soil poses a higher risk of nutrient loss through runoff.

The Animal Manure Management team has opted to change the format of live Land Application Training events this year. In February and March, the team will host a series of three1.5-hour long zoom sessions that will serve as the first portion of initial land application training. Recertification training and the last segment of initial training will be held at a later date, hopefully in-person. Anyone is welcome to participate in the zoom sessions, but participation at each session will be limited to keep them interactive and informative.

Current manure application practices have little to no precision application capabilities compared to other modern agricultural equipment. Due to some recent emerging technologies being released on the market, manure application is finally joining the digital age. This article summarizes these new precision manure application technologies.

The UNL manure team has been working on building an app to connect the public to the manure people they need, and maybe learn a little bit about manure along the way. Our goal with the app is to enable folks to find a manure applicator, broker, advisor, or resource person in their area. We’ve been testing and updating, and we think it’s ready for its full debut! The app is available for both Android and Apple devices.

Manure produced in animal feeding operations is a source of fertilizer that can be used to reduce our dependency on commercial fertilizers. Manure contains several essential nutrients that crops that crops rely on to grow, most notably nitrogen and phosphorus. Proper management of manure before, during, and after land application helps to slow down the contamination of our streams and reservoirs.

There are many challenges associated with variable rate manure applications such as variable nutrient content within the manure source and nutrient availability, application equipment, and prescription methodology. However, in many cases, these challenges are outweighed by environmental and economic benefits from variable rate manure applications.

This year’s Land Application Recertification sessions, called Applying Manure Management Concepts On-Farm, are scheduled to be in-person at many locations across the state in June, with one taking place in May in Lexington. Manure trainings earlier this year were held virtually, but we’re making progress, and that means we’re looking forward to seeing everyone in-person for the next manure event.

When it comes to animal manure from feedlots being applied to the land in Nebraska, developing management practices that efficiently uses the nutrients from manure while being environmentally sustainable can be a complicated process. This article introduces some land application approaches for beef and dairy feedlot systems.
