This factsheet explains the three factors of proper swine manure management: the nutrient content of the manure, the percentages of those nutrients that are available to the plant and the nutrient requirements of the plant.
Air quality in hog production can be improved by dietary manipulation (e.g., reducing crude protein), technology (spraying oil in the houses), management (regular washdown of pens), or additives. This paper focuses on additives used in shallow pits and lagoons.
Applying swine manure to forestland that needs nitrogen and phosphorus can help swine producers manage waste and put valuable nutrients to work for forest owners. This publication is based on a research project designed to investigate factors that make fertilizing with animal manures successful in North Carolina.
