Value of Manure

What is the Economic Value of Manure?

Value of beef open lot manure assuming crop benefits from potassium supplementation and 5% increase in yield. Estimated manure value is $28/ton.
Manure has value. That value may result from improvements in soil quality, increases in yield, and replacement of commercial nutrient required for crop production. This article will focus on the economic benefits of manure.

Manure Impact on Erosion and Runoff

Manure's ability to improve soil properties can reduce erosion and runoff.
This article reviews the value that results from changes to soil’s physical characteristics. Charles Wortmann and Dan Walters, faculty with the University of Nebraska-Lincoln monitored soil erosion, runoff, and phosphorus (P) loss from replicated field plots over three cropping seasons immediately after manure application and four subsequent years when no manure was applied. Significant erosion and runoff benefits were observed for sites receiving animal manures.

Manure Impact on Soil Aggregation

The organic matter in manure improves soil quality including formation of stable soil aggregates.
Manure increases formation of larger and more stable soil aggregates. Several benefits result for fields fertilized by manure compared to commercial fertilizer including reduced runoff and soil erosion and increased water infiltration leading to greater drought tolerance.

Farmers and ranchers are becoming increasingly aware of the importance of soil quality/health to the productivity and sustainability of their agricultural system. Research and field observations have demonstrated that carefully managed manure applications can contribute to improved soil quality with limited environmental and social risks. However, a comprehensive assemblage of outputs and conclusions from research studies, field trials, soil labs databases, and other sources has never been developed.
