But while James Brooke, a partner in land agents Bidwells was referring to top-grade arable land, the rich pastures of the Westcountry, famous for all-year-round grass, might not be far behind.
Mr Brooke was speaking at the major national arable event, Cereals 2013, in Lincolnshire. He said the ongoing rise in land values, particularly for Grade One land, would continue, and could hit £20,000 by the year 2020.
Demand for land was being driven by an ever-increasing world population that needed to be fed, he said. That demand for good agricultural land would continue to grow.
"There is no indicator as to why the current trajectory of land-price travel should fall. I see no reason as to why £20,000 per acre should not be achievable."
He urged farmers to work within reasonable budgets and not over-extend their borrowings. Farmers seeking to expand would want to purchase more land before prices increased much higher, but he said they should be inventive when drawing up plans for future expansion.
Mr Brooke said land that was adaptable to produce different crops and also to withstand climate change would be particularly sought after in the future.
"There is a need for good-quality land in good areas with good irrigation and drainage. We need to be able to grow crops which can adapt to climate change," he stressed.
Currently the Westcountry is the most active region for farm sales, according to estate agents Smiths Gore. Its Taunton office reports over 50% more land was marketed nationally this spring compared with 2012, in what is traditionally the busiest period for farmland market activity.
But, as 2012 had the least land marketed on record, the amount for sale remains very low and will not satisfy demand, explained specialist agent Simon Derby.
"Although the land marketed was a considerable increase compared with last year, we do not expect there to be much more land sold over the whole year compared with last," he said.
Smith Gore's analysis shows that up to a quarter of all the land marketed throughout the year was advertised in April and the first half of May.
