On or before July 1 the assessor shall mail to each taxpayer whose land has been valued, assessed, and taxed for the then current tax year pursuant to the "Farmland Assessment Act of 1964" a copy of the form prescribed to claim a continuance of valuation, assessment and taxation under such act for the succeeding tax year together with a notice that the completed form is required to be filed with the assessor on or before August 1.
The failure of any taxpayer to receive a form for claiming continuance of a farmland assessment shall not relieve him of the requirement to claim and establish his right thereto as required by law.
