Iowa Code § 161A.54
Each state agency shall enter into an agreement with the soil and water conservation district in which the state agency has public land under its control in cultivation. The agreement shall contain a plan of the state agency to prevent soil erosion in excess of soil loss limits by the use of soil and water conservation practices and erosion control practices. This section applies to all public land which is used for horticultural or agricultural purposes. State soil conservation cost-sharing funds shall not be used on these public lands. Conservation plans required by this section shall be completed by July 1, 1986, and implementation shall occur consistent with the schedule contained in the conservation plan. Application for exemption from this section may be submitted to the appropriate soil and water conservation district. The exemption shall be granted for land upon which soil management research for the purposes of the study, evaluation, understanding and control of erosion, sedimentation and run-off water is conducted by or in conjunction with institutions governed by the board of regents.
