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.
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 explains how to use dairy manure as a fertilizer source. Included are descriptions of nutrient content, application rates and application methods to ensure optimum benefit from the manure. A worksheet is provided for calculating application rates.
This publication offers fertilizer suggestions for a variety of crops, including field, pasture and hay crops, tree fruit, small fruit, ornamental plants and vegetable crops.
Phosphorus (P) is the second most important nutrient in crop production but is often found in relatively low amounts in native soils. Decades of fertilizer application have led to P enrichment of most North Carolina agricultural soils. Excess soil P that leaves agricultural fields via runoff and drainage can cause algal blooms in water resources that lead to impaired drinking water quality and can limit recreational activities. Maintaining adequate soil P levels for crop growth can reduce P runoff, save money, and protect the environment
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.
This publication provides recommendations for managing essential nutrient concentrations when growing organic tobacco in greenhouses using a float system.
