Table 6 Nutrient loading coefficients according to manure production & weight reduction cases (Simple static pile composting)

From: Nutrient production from Korean poultry and loading estimations for cropland

Weight reduction scenarios Manure production cases
Nutrients Case Ia Case II Case III
A (Farm Investigation) VS 0.52 0.51 — b
N 0.44 0.43 0.62
P 0.48 0.47 0.52
B (ΔP = 0) VS 1.20 1.20 — b
N 0.95 0.95 1.19
P — c — c — c
  1. aCase I, manure production from questionnaire x nutrient concentrations in compost from farm sample; Case II, manure production reported by ME x nutrient concentrations in compost from farm sample; Case III, manure production reported from ME x nutrient concentrations in compost from ME
  2. b = Organic component of the ME is not to be compared referred to as BOD
  3. c = P coefficient is 1.0
