for land application.
Assuming land application at agronomic rat& with no additional
See Appendix 6 for calculation details.
Because the cost figures are based on different units than the effectiveness
estimates, units had to be converted based on the range of agronomic land
application rates. The following equation was used to perform the conversions:
. kg reduced
hectares
head
kg reduced
hectares of land application
year
head-year
The parameters for the above equation vary by animal type and by the nutrient
needs of the receiving crop. Table 2-12 summarizes these parameters and
presents the resulting ranges of estimated cost-effectiveness values.
