(1) Sixteenth section lands, or any lands granted in lieu of sixteenth section lands, classified as agricultural may be leased for the cultivation of rice, or pasturage, for a term not to exceed ten (10) years. All other sixteenth section or lieu lands classified as agricultural may be leased for a term not exceeding five (5) years. All leases of land classified as agricultural shall be for a term to expire on December 31. Except in those cases when the holder of an existing lease on agricultural land elects to re-lease such land, as authorized under this subsection, it shall be the duty of the board of education to lease the sixteenth section or lieu lands at public contract after having advertised such lands for rent in a newspaper published in the county or, if no newspaper is published in the county, then in a newspaper having a general circulation therein, for two (2) successive weeks, the first being at least ten (10) days before the public contract. The lease form and the terms so prescribed shall be on file and available for inspection in the office of the superintendent from and after the public notice by advertisement and until finally accepted by the board. However, before the expiration of an existing lease of land classified as agricultural land, except as otherwise provided in subsection (2) for lands intended to be reclassified, the board of education, in its discretion and subject to the prior approval of the Secretary of State, may authorize the holder of the existing lease to re-lease the land, on no more than one (1) occasion, for a term not to exceed five (5) years and for a rental amount that is no less than one hundred twenty percent (120%) of the total rental value of the existing lease. If the holder of the existing lease elects not to re-lease the land, the board of education shall publish an advertisement of agricultural land for rent which publication shall be not more than four (4) months before the expiration of the term of an existing lease of the land. An election by the holder of the existing lease not to re-lease the land shall not preclude his participation in the bidding process established under this section. Subject to the classification of the land, the board of education shall enter into a new lease on agricultural land before the expiration of an existing lease on the same land, and the new lease shall take effect on the day immediately following the day on which the existing lease expires. The board of education may require bidders to furnish bond or submit evidence of financial ability. Bids received by the board of education in response to the advertisement shall be opened at a regular or special meeting of the board. The board of education, at its option, may reject all bids or accept the highest and best bid received in response to the advertisement, or the board of education may hold an auction among those who submitted bids in response to the advertisement. If the board of education elects to hold an auction, no bidder shall be granted any preference. The opening bid at the auction shall be highest bid received in response to the advertisement.
