If a proper application by a landowner is approved for lands that qualify for valuation, assessment and taxation as being actively devoted to agricultural, horticultural or agricultural and horticultural uses for any tax year that property is revalued and certified, that portion of any tax assessed for such year which is in excess of the tax that otherwise would have been assessed on such lands had the approval been made timely, shall be abated.

If such application is approved and the lands qualify for valuation, assessment and taxation as lands maintained for recreational use in such tax year, the portion of any tax assessed for such year which is in excess of the tax which would have been assessed on such lands had such application been timely made and approved shall be abated.
