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 publication discusses how excess zinc and copper from animal manure can lead to soil toxicity and harm crops in North Carolina. It covers where zinc and copper come from, potential harmful effects, and ways to prevent toxicity. Management strategies include soil testing, accurate manure application, record-keeping, and adjusting animal feed. Mitigation methods like soil turnover and pH modification are also discussed.
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 training program is designed to provide operators of animal waste management systems with the basic understanding needed to operate and maintain these systems in an efficient and environmentally sound manner.
