It is the intent of the General Assembly that farmers be offered an incentive to use agricultural best management practices as part of an approved nutrient or odor management plan, manure management plan, agricultural erosion and sedimentation plan or Federal conservation plan to prevent nutrients from washing off farm fields and animal concentration areas and entering surface water and groundwater, to prevent soil erosion, to reduce or mitigate odor and to conserve land, water and related natural resources. These incentives shall take the form of low-interest capital in exchange for the implementation of such approved practices.
