for controlling nonpoint source pollutant losses (e.g., pollutant mitigation,
water treatment, and discharge).
This total cost for pollution control is divided into three parts: control
of soil loss, management of solid-state N and P, and control of dissolved
N and P. In this model, management of solid-state N and P is
additionally required by the local government. This aims to prevent
them entering the surrounding water environment through technically
enhancing N and P utilization efficiency and cutting off the linkage between
N and P sources and their potential migration paths.
In specific, the total revenue from the three agricultural activities can
