Talks were based around Defra’s newly published Farming Roadmap, which sets out the government's ambitions for farming over the next 25 years.
The NFU is calling for the urgent Treasury investment to ensure this can be delivered.
Issues discussed included environmental support schemes, biosecurity, EU realignment, planning, fuel and fertiliser prices, water security, the struggles facing abattoirs and the need to build resilience in the British farming industry.
Thursday’s meeting was one of several NFU members held with politicians representing five political parties over the two days of the show.

NFU Norfolk Vice-chair Will Sargent, who farms near Long Stratton, said: "We have met with representatives of several parties and every person on the NFU stand has been open and listening to what we had to say.
"We will keep talking to them to keep finding solutions. Despite the challenges, we remain optimistic for the future of farming, particularly here in Norfolk, where the industry is so vital to the county."
He added: "It is important to get early engagement with the new Farming Minister as we have done at every show in the past.
"He is in listening mode and we look forward to working with him more in the future.
"We will keep championing our farming industry and engaging at all levels of government."
Constructive discussions with the NFU
Mr Morgan said: "It was an enormous pleasure to be at the Norfolk Show to hear directly from farmers from Norfolk about the opportunities and challenges facing their businesses and farming communities.
“This week we set out our Farming Roadmap, providing a long-term plan to help make English farming profitable, productive, sustainable and resilient for generations to come.
“Farming is at the heart of our countryside, our food security and our economy, and there is no substitute for hearing from the people who make it happen every day.
“I am passionate about the future of farming and welcome the constructive discussions with NFU members on how we can work together to build a stronger and more confident farming sector."

The meeting came at the end of a packed two days at the show. This included discussions with many of the county’s MPs, Shadow Defra Minister Dr Neil Hudson and engagement with county councillors to discuss developments around Norwich Livestock Market and other topics.
The NFU also hosted US Agricultural Counselor Anita Katial, to talk about agricultural trade and international opportunities, and Show President the Rt Revd Graham Usher, the Bishop of Norwich.
NFU Deputy President Paul Tompkins made his first visit to the show on day one. As well as member engagement on the stand, including meeting with younger members and a discussion on water, he toured the cattle lines with Regional Director Zoe Leach and former county chair Ken Proctor.
He also spoke at a members’ reception, where he highlighted the essential role played by agricultural shows in building public support for British food and farming.
