Mouse over the bottom of the slide to slow or pause slides.

Thirteen swine producers from Corn Belt states participated in a project with faculty from University of Nebraska and Purdue University to understand the movement of nutrients (nitrogen and phohsphorus) on commercial swine facilities.…

Managing Manure on Horse Farms

Why Is It Important to Manage Horse Manure?

When managed properly, nutrients from manure should be seen as part of a larger cycle occurring on the farm. Nutrients enter the farm as feed or fertilizer, are excreted as manure, and are subsequently spread on the soil, taken up by plants, or transported off the farm as waste.…

USDA Small Farm Definitions

Farm Classification System

The USDA Economic Research Service (USDA-ERS) has developed a farm classification system to divide U.S. farms into eight mutually exclusive and more homogeneous groups. The farm typology focuses on “family farms,” or farms organized as proprietorships, partnerships, and family corporations that are not operated by a hired manager.…

Pathogens and Potential Risks Related to Livestock or Poultry Manure

Links to PEDv (Porcine Epidemic Diarrhea Virus).


Microorganisms (e.g. virus, bacteria, protozoa, and fungi) surround us, on us, and in us; they are ubiquitous and everything in the world is governed by them.  They are part of our everyday lives.  They influence the the quality of our soil, food grown on that soil, and how our body reacts to that food.…

Feed Management Planning as a Tool to Reduce Nutrient Excretion

Why is Feed Management Important to Nutrient Planning?

Feed represents the largest import of nutrients to the farm, followed by commercial fertilizer. Feed management practices impact the amount of nutrients that are imported to the farm and excreted in manure. The excreted nutrients are subsequently available for volatile loss (nitrogen) to the atmosphere and potentially lost via surface runoff (nitrogen and phosphorus) or leached to ground water (nitrogen and phosphorus).…

Manure Management on Small Farms

What Does “Small Farm” Mean?

Small farms are typically smaller in size, with fewer animal numbers, less acreage and have a lighter regulatory burden than larger farms, which may often be designated as Concentrated Animal Feeding Operations or CAFO’s. Small farms are often able to implement lower cost solutions to animal waste concerns than are larger farms.…
