Laboratory Certifications
Waste analysis helps growers make responsible decisions about the use of farm, municipal and industrial wastes and by-products as fertilizer materials for crop production. Predictions of first-crop nutrient availability are provided according to application method (e.g., surface broadcasting, soil incorporation, injection or irrigation). Laboratory analyses for total Kjeldahl nitrogen, total phosphorus, copper and zinc are certified by the state's Division of Water Quality for compliance with the environmental regulations specified in N.C. Senate Bill 1217.

Waste analysis can also be used to determine the stability and quality of composted materials or to guide the mixing of raw materials for optimal composting. In addition to the standard measurements included on the Waste Analysis Report, a compost analysis includes carbon, carbon-nitrogen ratio, pH and soluble salts (electrical conductivity).

Sample Containers Sample containers are not provided by NCDA&CS. For liquid waste, submit 12–16 oz of a representative waste sample in a plastic (not glass) bottle. Used beverage containers with the labels removed work great! Be sure to rinse the container prior to sampe collection; do not use soap. For solid waste, submit 1–2 quarts of a representative sample in a sealed plastic bag.
