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 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.
Soil samples that determine lime and fertilizer needs of crops routinely come from the top 4 to 8 inches of soil. However, deep soil samples will be needed for the Phosphorus Loss Assessment Tool (PLAT), and this publication describes how to take these 28- to 32-inch deep samples.
This publication discusses the Realistic Yield Expectations database as a resource for nitrogen fertilization rate decisionmaking. Topics include recent research and the resulting updates to the database for improved nitrogen fertilizer rates based on new yield data.
