Conservation of agricultural land.

Requires each board of county commissioners to adopt an ordinance to allow landowners to apply to have land included in an agricultural resource area within the county. Specifies certain procedures and requirements for the agricultural resource area programs. Provides provisions that apply to land within a program, including eminent domain provisions, a prohibition against annexation for nonagricultural purposes, certain priority provisions for specified funding, and authorization for a county option property tax deduction for land located within agricultural resource areas in the county. Authorizes the Indiana state department of agriculture (department) to receive and hold agricultural conservation easements acquired by gift, bequest, or devise and to enter into agreements with nongovernment entities to monitor those easements. Establishes the farmland advisory board for the purpose of advising the department on developing standards for accepting, monitoring, and enforcing agricultural conservation easements it may hold, creating a model agricultural resource area ordinance, collecting feedback on agricultural resource areas, and supporting education and outreach about agricultural resource areas.
