Manure and the Environment

Manure contains four primary contaminants that impact water quality: nitrogen, phosphorus, bacteria and other pathogens, and organic matter. Achieving a nutrient balance will reduce potential environmental hazards often associated with animal agriculture. An annual crop nutrient management plan is needed to ensure an adequate supply of nutrients to sustain profitable crop production, and to balance nutrient inputs (including manure) with crop nutrient needs.

When I reached the top, and the crowd around me had parted, I thought for a moment I might suddenly have traded places with Samwise Gamgee, hobbit, because I was gazing out onto a field of what reminded me very much of the steaming slag pits of Mordor.  However, rather than an apocalyptic hell-scape I was instead looking at a premier example of sustainable agriculture.

Muddy Feedlot Surfaces: What Are My Options?

Muddy feedlot conditions common in Nebraska in 2019 lead to poor animal performance, some health issues, and increased odors as temperatures warm. What are your options for minimizing these challenges?
An undesirable combination of precipitation events and freeze/thaw cycles has contributed to some very muddy feedlot surfaces in the winter and spring of 2019 in Nebraska.
