Figure 1.1.7. Percent manure pack vs. animal unit density.
(from Young et al., 1982)
[percent manure pack x 45 x (V1 + 30) + 60 (V2-30) ] / (V1 + V2) = COD
(1.1.24)
[percent manure pack x 0.85 x (V1 + 30) +2 (V2-30) ] / (V1 + V2) = P
(1.1.25)
[percent manure pack x 3 x (V1 + 30) + 12 (V2 -30) ] / (V1 + V2) = N
(1.1.26)
Determine pollutant concentration at feedlot edge (CF) by adding runoff water and pollutants from
Area 1 and Area 2:
CFVF = C1V1 + C2V2
(1.1.27)
Where:
CF = concentration of runoff at the feedlot edge (mg/1)
VF = volume of runoff at feedlot edge (ac-in)
C1 = concentration of runoff in the feedlot (mg/1)
V1 = volume of runoff from feedlot (ac-in)
C2 = concentration of runoff from Area 2 (mg/1)
V2 = volume of runoff from Area 2 (ac-in)
Default values for Area 2 and Area 3 background concentrations for P, COD, and N are provided
in Table 1.1.5 and Table 1.1.6
1.1-24
