This publication addresses nutrient management concerns as they relate to land application of animal wastes, municipal biosolids, industrial residuals and agricultural by-products, with a focus on phosphorus application and its impact on the environment. Methods for reducing phosphorus loss from land application sites are presented as general guidance for managers of land application systems, who must be knowledgeable of regulatory issues and permit restrictions as they relate to phosphorus and nutrient management.
This fact sheet discusses different types of amendments that can be used to manage ammonia levels in broiler houses.
This publication addresses application techniques that affect drift and odor problems associated with wastewater application, so that managers and designers of land application systems can make wise decisions on how to apply wastewater with minimal impact on neighbors and the environment.
This publication provides two simplified recipes for bin composting of routine poultry mortality for producers who may not have complete information about the carbon to nitrogen rations for the amendments available to them.
This publication provides information about building a simple yet effective system for reducing odors and dust emissions from swine barns.
This publication describes hose drag systems and their operation as used to apply animal waste and wastewater in North Carolina.
Hose-drag-type equipment has gained popularity in recent years for land application of wastewater in North Carolina. It offers several advantages over traditional irrigation systems including odor reduction, nitrogen conservation, and a relatively high flow rate that cuts the application time. This publication explains calibration procedures for the “low-profile-type” discharge system and a “boom-type” system.
This publication discusses using poultry waste as a nutrient treatment for field crops. It provides practical information that can be used to calibrate spinner spreaders for the most effective land-application of poultry litter. A spreader calibration worksheet is included.
Due to pollution concerns federal and state regulations and incentives (discussed in this publication) have been established to store poultry waste in a way that reduces pollution and minimizes nutrient losses and odors. Because poultry waste storage regulations vary among states, it is important to check whether a storage method (depending on duration of storage) is acceptable in a particular state.
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.
As heat stress is one of the most significant management challenges facing the N.C. turkey industry, this publication reviews ventilation for the cooling of heaving strains of turkeys during the growing period after brooding.
