Table 5 Nutrient loading coefficients according to manure production & weight reduction cases (Dry 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 1.44 1.44 b
N 0.90 0.90 1.35
P 1.33 1.33 1.64
B (ΔP = 0) VS 1.36 1.36 b
N 0.64 0.64 0.80
P c c b
C (Dry basis) VS 0.56 0.56 b
N 0.33 0.33 0.50
P 0.47 0.47 0.58
  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. bOrganic component of the ME is not to be compared referred to as BOD
  3. cP coefficient is 1.0
