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”.

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.

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.

The misconception about manure being just a waste and harmful biproduct of the cattle and livestock industry is still a big concern. A group of researchers and extension educators have joined efforts with farmers across Nebraska to find the value of manure as a source of nutrients in crop fields in the Sandhills and reduce the environmental impacts caused by this industry. At the same time, they are trying to incorporate residues from red cedar trees that are currently threatening the Nebraskan wildlife and ecosystems due to its rapid expansion.

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.
