Charles visited Trefranck Farm, near Launceston, on Tuesday, which was hosting the 10th anniversary of the Innovative Farmers initiative.
Founded by charity the Soil Association, of which Charles is a patron, it is a network of producers developing nature-friendly alternatives to intensive farming practices.
The prince met with farmers switching to “herbal leys” – a mix of clover, grasses and wildflowers for grazing – instead of just a monoculture of rye grass favoured elsewhere.
While most of the country bakes in unprecedented heat and grassland lies dry and yellow, the team at Trefranck showed off their rich green landscape.
Kate Still, of the Soil Association, told the PA news agency: “More and more farms are embracing this kind of diversity and going for these diverse swards – and more and more non-organic farmers.”
She said that many more would make the switch, otherwise they would have nothing to feed their livestock as the frequency and intensity of heat waves increase due to climate change.

James Daniel, of consultancy Precision Grazing LTD, explained farmers are also switching to “mob grazing” – where animals are regularly moved from field to field instead of grazing the grass down to the roots.
“It is about moving animals more often, only letting a group of animals stay in one place for three to five days,” he said.
“It is about changing how you manage animals and it is more natural, before we started putting up fences and hedges, they would have roamed free.”
Mr Daniel said the prince was already well aware of the practice.
“The prince said to us: ‘In order to farm for the future we need to give a little bit back to nature’,” Mr Daniel said.
Charles also met with farmers breeding sheep resistant to gut parasites in order to reduce the reliance on chemical wormers, and people developing satellite technology to help manage grazing land.
In a speech, the prince said: “I have always felt at the end of the day we have over exploited nature for too long – we have lived off her capital, without understanding we need to live off income.”
He continued: “To get back to that we need to make sure whatever little profit we make, there is a bit of profit for nature at the same time.
“That way I think we might start to rebalance and get back to the point we can rescue this poor old planet for all our successors, otherwise we are running out of time very rapidly.”
