Estimates of Surface and Subsurface Nutrient Loss from Land Application
2x Agronomic Rate
3x Agronomic Rate
4x Agronomic Rate
Agronomic application rates of animal wastes are typically based on the nitrogen content of the waste (J
Barker, 1994). The phosphorus content of the waste will vary by animal type and by the level of pre-
fresh vs. lagoon). The N:P ratio in the waste may also vary from
The ranges presented for phosphorus account for this

Based on the mass loss estimates in Table 2-4 and the cost estimate in Table 2-
2, we present estimated
for land application
