Reprogramming of the laboratory-information-management system that makes this report possible is being funded
through a grant from the North Carolina Tobacco Trust Fund Commission.
Thank you for using agronomic services to manage nutrients and safeguard environmental quality.

Nutrient concentrations and other data on this report are provided so that waste materials can be applied at agronomic rates, thereby supplementing or reducing fertilizer
application and preventing environmental contamination. In reading the Laboratory Results section, remember that materials with < 15% dry matter (generally liquids) are
analyzed as received; all other wastes are dried first. Values in the Estimate of Nutrients Available for First Crop section are based on the type of waste and method of
application you specify and reflects the fact that only 40-60% of the nitrogen becomes available within one year of application. The remainder may or may not ever become
available.
Understanding the Waste Report

meq/L = milliequivalent per liter;mS = millisiemens;ppm = parts per million or mg/L;S = siemens;T = trace (<0.005 lb/unit)
NH4-N =Ammonium -N
Ni = Nickel
NO3-N =Nitrate -N
P = Phosphorus
Pb = Lead
S =Sulfur
Se = Selenium
Cu = Copper
Fe = Iron
K = Potassium
Mg = Magnesium
Mn = Manganese
Mo = Molybdenum
N = Nitrogen
Na = Sodium
Al = Aluminum
As = Arsenic
B = Boron
Ca = Calcium
Cd = Cadmium
Cl = Chloride
Cr = Chromium
DM% is percent Dry Matter [for semi-solid and
solid waste, this value facilitates conversion of
dry-basis concentrations (ppm) back to
wet-basis of original sample].
EC (Electrical Conductivity) measures
salinity, or soluble salts (SS).
pH measures basicity/acidity.
ALE is Agricultural Lime Equivalence. The ALE
indicates the amount of the waste material that
provides a limiting effect equivalent to one ton of
agricultural grade limestone.
BD is Bulk Density in lb/yd³.
CCE is Calcium Carbonate Equivalence and is
used to determine ALE.
C:N ratio is the Carbon:Nitrogen ratio.
