Animal Manure Management

Recycling local manure nutrients before purchasing fertilizer is key to protecting the environment. Manure can be an economic “Win”, due to its fertility value, and a soil quality “Win”, due to its organic matter.  But it can also be a community risk, due to odors and pathogens. Our live educational programs, online courses, and resources provide science-based information on economically viable, environmentally sound manure handling systems that also comply with all regulations.

Planning 2021 Fertilizer-N Application Following a Dry 2020

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?

Managing Weed Seeds in Manure

Weed Seeds in Manure
Small but mighty, weed seeds in manure can be problematic when they result in overgrown, weedy fields after manure application. Some manures can be a source of these troublesome weed seeds. But, luckily, there are some measures that can be taken to reduce the viability of those weed seeds.

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

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”.
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.

Water productivity in meat and milk production in the US (Part II)

Growth in the livestock sector has a lot of potential to benefit Nebraska economically, however it can also have negative impacts on our natural resources. To address some of these environmental impacts, the sector has been working hard to improve livestock water productivity. Recently, scientists at the Daugherty Water for Food Global Institute and the Department of Animal Science of the University of Nebraska, together with colleagues from the University of Twente, and the National University of Singapore worked together to estimate the changes in water productivity of animal products from 1960 to 2016.

Water productivity in meat and milk production in the US from 1960 to 2016 (Part I)

graphs comparing livestock production to 1960 levels
Livestock production plays an important role in rural and urban economies worldwide and is a significant source of protein in humans’ diet. However, the growth of the livestock sector can have negative impacts on our natural resources; fresh water consumption, water quality deterioration due to manure nutrient losses to surface water, greenhouse gas emissions, and competition for human-edible grains are all possible consequences of food animal production. To address some of these environmental impacts of livestock production, the sector has been working hard to improve livestock productivity, feed-use efficiency of animals, crop productivity and efficiency of resource utilization in the field, and expanding the sourcing of feeds.
