Review of Odor Management Planning Templates and Calculators Across the US

Proceedings Home | W2W Home waste to worth 2017 logo

Purpose

Odor is a common and prevalent problem for new and existing livestock operations, and odor is often a source of conflict between neighbors. Odor cannot be removed in entirety from livestock production, but it can be managed. A few states have developed odor management plan guidelines or templates that may be mandatory, or voluntarily for the sake of good stewardship.…

Modeling water movement in beef cattle bedded manure pack


Why Examine Moisture Content of a Manure Pack?

Bedded manure is a valuable fertilizer source because it contains essential macronutrients (nitrogen (N), phosphorus (P), and potassium (K)) for crop production. Previous research with beef cattle bedded manure packs demonstrated that water-soluble macronutrients accumulated toward the bottom of the packs with water movement.…

Abstract

The economics and environmental impacts of livestock production cross watershed boundaries and affects both rural and urban populations. In particular, the issue of manure management has been the subject of debate and new policies in recent years as the non-point source discharge of nutrients and bacteria can be substantial if manure is not managed properly.…

Why Study Air Emissions from Mono-slope Beef Barns?

Mono-slope buildings (Figure 1) are one type of roofed and confined cattle feeding facility that is becoming increasingly popular in the Northern Great Plains. However, little is known about the impact of these housing systems and associated manure management methods on the air quality inside and outside the barn. …

Mono-Slope Beef Barns

There is growing interest in feeding cattle in bedded confinement buildings for a multitude of reasons including (but not limited to): performance advantages, limited space for open lots, and keeping manure dry as well as preventing feedlot run-off and reducing environmental concerns. Oftentimes these confined cattle are housed in mono-slope barns.…
