Agriculture Secretary Sonny Perdue is credited with dissuading Trump from abandoning NAFTA last April by showing the president a heavily rural map of states that would be hurt by US withdrawal.
"Farm country is God's country", he declared.
Trump spent some time in his address on the new tax law he signed shortly before Christmas, telling producers about the $5.5 trillion in tax cut that will be offset by $4 trillion in other revenue changes.
He says tax cuts and the doubling of the threshold for the estate tax will help farmers and they'll benefit from the cutting of red tape.
And in what he called the "sleeper of the bill", Trump said all businesses, including farmers, will be able to deduct 100 percent of the cost of new equipment in the year the investment is made-as opposed to over many years.
"We are witnessing a new era of patriotism, prosperity, and pride-and at the forefront of this exciting new chapter is the great American farmer", he said.
President Donald Trump reminded farmers on Monday how lucky they were to have had the chance to vote for him.
About 7,000 farmers are attending the event which is held at Gaylord Opryland Resort & Convention Center January 5 – 10
It was the first time a president had spoken at the annual convention of the nation's largest farm organization since George H.W. Bush appeared in 1992, and Trump peppered his speech with praise for farmers.
"I'm so honored to be the first President to address the American Farm Bureau in more than 25 years", said President Trump.
At Berry Airfield, home of the 118th Wing of the Air National Guard, Congressman Scott DesJarlais was among those who welcomed President Trump to Tennessee as the President deplaned from Air Force One.
President Trump also promised to pass the next Farm Bill before legislation funding support schemes for USA farmers expires on 1 October. "And we're fighting for our country", he said.
The president hit all the high notes to please the crowd that helped elect him to the White House, from lower taxes to increasing rural broadband access, but only briefly mentioned trade and NAFTA, which farmers are most concerned about when it comes to administration policy. Chuck Fleischmann were among those accompanying the President to Nashville.
Tennessee Republican Party Chairman Scott Golden said, "Tennessee Republicans stand with President Trump and his commitment to farmers and rural communities across Tennessee".
Trump also spoke of adding better internet connectivity to rural regions, something he hopes will increase job attraction to such communities. Some even wore red Trump hats emblazoned with variations on the "Make America Great Again" slogan.
