Section 12. Assessment and taxation of land devoted to agricultural use

Land devoted to agricultural use may be defined by law and valued for ad valorem tax purposes upon the basis of its agricultural income or agricultural productivity, actual or potential, and when so valued such land shall be assessed at the same percent of value and taxed at the same rate as real property subject to the provisions of section 1 of this article. The legislature may, if land devoted to agricultural use changes from such use, provide for the recoupment of a part or all of the difference between the amount of the ad valorem taxes levied upon such land during a part or all of the period in which it was valued in accordance with the provisions of this section and the amount of ad valorem taxes which would have been levied upon such land during such period had it not been in agricultural use and had it been valued, assessed and taxed in accordance with section 1 of this article.
