With increasing regulations, the livestock producer needs to understand the scientific principles that affect manure transformations and how to use these principles to manage the manure for maximum fertilizer value with minimal environmental impact. Improved land application of manure is one part of the solution, but we suggest that the producer evaluate the quantity of nutrients arriving on the farm as feed, animals, and fertilizer compared to the total that is exported.

The science behind 50-degree soil and nitrogen application

Does nitrogen becoming nitrate mean we are going to lose it? No, it takes rainfall or snowmelt in the spring that will cause a leaching event, but it does increase the risk of loss. Certainly, there is a balance between making sure we get our manure applied before the soil freezes and applying too early, but hopefully the information above illustrates a bit behind the science of the 50°F and cooling recommendation.

Poultry Litter’s Agronomic and Natural Resource Benefits

Many Nebraska farmers are experienced with using beef feedlot and swine manures as fertility products. Over the next few years, Nebraska crop farmers may have opportunities to consider using broiler poultry litter as a soil amendment and fertilizer. Other regions of the US have a history of using poultry litter in crop production from which we can take away a few lessons.

Demystifying Poultry Manure: Best management practices for optimizing agronomic value and minimizing environmental risks

Calling all crop producers who are considering using poultry manure…and rural citizens who want to learn more about poultry manure management!

Manure Nitrogen Use for Increased Profit and Environmental Protection

For many years, the University has used a recommended equivalence of 47% available over the course of 3 years for feedlot manure, 37% for compost, and 52% available for poultry manure with litter. Recent research shows that these numbers may be a little low, but they are intentionally conservative so as not to limit yield due to nitrogen deficiency.

Soil sampling for better fertilization decisions

Recommendations for collecting soil samples to ensure the quality results needed for good management decisions about fertilizer, manure and lime application rates.

Proposed Changes to Nebraska Recommendations for Manure Nitrogen Credit

Managing manure for economic and environmental benefit is based, in part, upon our ability to efficiently recycle manure nitrogen (N) between animals and crops. This article introduces University of Nebraska-Lincoln (UNL) proposed changes in recommendations for crediting manure nitrogen in a crop’s fertility program.

The connection between soil organic matter and soil water

One benefit of increasing soil organic matter is to store more water in your soil. Why does this happen? Because soil organic matter creates pores in a range of sizes. Exactly how much more water is stored due to soil organic matter will depend on soil texture, though. Animal manures are one option for increasing soil organic matter and soil health.

Emergency use of milk as a fertilizer Q&A

Difficult challenges in the dairy industry such as those resulting from COVID-19 result in times when a market is not available for milk. When those occur, using milk as a crop fertilizer may provide a short-term option for gaining some value from milk. This article will answer several questions about using milk as a fertilizer.

Extending the Manure Application Window: Post Plant Experiences

Extending the window for manure application offers many possible advantages. One can reduce some of the labor and equipment challenges associated with busy spring application windows as well as deliver nutrients to the crop more closely timed to the crop’s nutrient’s needs. Glen Arnold, Extension Specialist at Ohio State University recently met with a Nebraska audience to share field experiences in Ohio to side-dress manure into growing corn.

Can I Irrigate Animal Manures On Growing Crops?

High rainfalls can leave holding ponds or manure storage full and operators looking for irrigation options for applying animal manure during the growing season. This article discusses important considerations for application of open lot holding pond effluent and diluted manures during the growing season without damaging the crop.

What Are the Barriers and Benefits of Manure Use in Cropping Systems? (part 1 of 2)

Animal manures can be a “valuable asset” or a “pain in the assets”. Understanding the agriculture community's perceptions of manure's benefits and barriers is important to recycling manure nutrients efficienty. A survey of 957 individuals from the U.S. and Canada is helping us understand the next steps to encouraging manure's use as a valuable asset.

What Are the Barriers and Benefits of Manure Use in Cropping Systems? (part 2 of 2)

Animal manures can be a valuable asset or a “pain in the assets”. During winter of 2020, 957 farmers and their advisors shared their perspective on the benefits and barriers to manure use. A previous article (part 1) focused on perceptions of manure's benefits. This article (part 2) focuses on their perceptions of manure’s challenges that commonly become barriers to manure use in some fields and discusses strategies for preventing manure from becoming a “pain in the assets”.
