This factsheet for farmers describes ways to control the harmful effects of excess nutrients while maintaining healthy, productive farm crops. Steps covered include testing your soil and following the soil testing recommendations, setting realistic yield goals, choosing the most suitable nitrogen sources, applying nitrogen correctly, using manure as a nutrient source, controlling erosion, managing water flow and fencing animals away from water flow.
This factsheet describes the nutrient composition of poultry manure and land application techniques based on matching the nutritional requirements of the crop with the nutrients available in manure. This publication also includes a worksheet to determine the nutrient needs of your crop.
This factsheet clarifies the importance of waste analysis and describes the procedures for taking reliable samples and submitting them to the Agronomic Division of the North Carolina Department of Agriculture & Consumer Services (NCDA&CS).
This publication provides updated recommendations for phosphorus fertilizer application in corn, soybean, and small grains crops. It includes background and historical information about phosphorus critical levels, phosphorus rate recommendations, phosphorus accumulation in soils, and changes in recommendations.
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 publication discusses how the Nitrogen Loss Estimation Worksheet Tool can be used to account for agricultural nitrogen levels as an alternative to water quality monitoring.
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.
