Technical Abstract: Environmental quality and livestock operations are considered to be at opposite ends of the spectrum. Water, air, and soil quality are considered to be at risk with livestock operations because of the concentrations of animals, manure, and facilities within a given area. Science provides an understanding of the movement of water flow around production facilities and within fields onto which manure is applied. Ground water can be protected with many different methods to ensure no movement of nutrients from production practices. This requires a knowledge of the geology of the site and the patterns of water movement. Surface water can be protected through the use of Best Management Practices. These practices can be used to prevent surface movement of phosphorus from fields. Science has developed these practices over a number of years. Soil quality can be improved through the use of manure, and science has developed an understanding of the processes that occur within soil. Air quality includes the components of air affected by livestock operations. These components are ammonia, hydrogen sulfide, volatile organic compounds, methane, nitrous oxide, and particulates. Science is being used to develop improved air sampling methods and knowledge about the generation, emission, and dispersion of these gases from buildings, manure storage, and manure application. Science can provide an understanding of the problems and the potential places where management alternatives can be used to create both an economic and environmental gain.
