funds expended on agricultural
in the Tar-Pamlico basin since the
the program in 1985 (Table 2-l). Other
were not addressed
because
historically low level of funding and the lack of adequate cost
and/or effectiveness data.

Manaaement
The following discussion presents the available data on cost and effectiveness of
these agricultural
in
basin.. For certain practices, sufficient
effectiveness studies existed
the cost-effectiveness of the practice.
For other practices, only cost data are presented because reliable effectiveness
results either did not exist or the effectiveness was so tied to site-specific factors
as to make generalizations inappropriate.
