Important Acronyms for Measurement
Nutrient Measurements are reported in mg/kg or mg/L for samples analyzed as solids or liquids, respectively. Nitrogen and carbon results are measured on an as-received basis for manures and manure-based composts and on a dry-weight basis for all other waste types. All other elements and calcium carbonate equivalent (CCE) are measured on a dry-weight basis
meq/L = milliequivalent per liter mS = millisiemens ppm = parts per million or mg/L or mg/kg S = siemens T = trace (<0.005 lb/unit)
ALE is Agricultural Lime Equivalence. The ALE indicates the amount of the material that provides a liming effect equivalent to one ton of agricultural grade limestone.
C:N ratio is the Carbon:Nitrogen ratio.
CCE is Calcium Carbonate Equivalent and is used to determine ALE.
BD is Bulk Density in lb/yd

Estimate of Nutrients Available for First Year
The Estimate of Nutrients Available for First Year are reported on an as-received (wet weight) basis for all elements in lb/ton or lb/1000 gal. The nitrogen estimate depends on the manure type and application method that you specify on the submission form and accounts for the fact that only 40-60% of the manure nitrogen becomes available within one year of application. All other elements and nitrogen from non-manure waste sources are reported as 100% available in the first year of application.

Conversion factor: Fertilizer grade (%) = mg/kg or mg/L ÷ 10,000
Conversion factors: lb/ton × 4.17 = lb/1000 gal.; lb/1000 gal. × 0.24 = lb/ton
DM% is the percent Dry Matter for semi-solid and solid materials. DM% is used to convert the dry-weight nutrient measurement concentrations (mg/kg) back to wet-weight concentrations of the original sample, as reported in the estimate of nutrients available for first year.
EC (Electrical Conductivity) measures salinity, or soluble salts (SS).
pH measures alkalinity/acidity.
