Good news for US farmland owners – the retreat in values looks more like that in the Great Depression than it does the 1980s' decline.
At least, to go by values in the Midwestern agricultural powerhouse of Iowa, the top US corn and soybean-producing state.
Iowa State University, in an annual farmland price update for the state, said that prices had fallen by 5.9% this year – the first time since the 1980s that values have fallen for a third successive year.
The drop in prices - to an average of $7,183 per acre, down 17.6% from their 2013 peak – has left many people "concerned about a potential farmland bubble burst", the university said, citing the dent to values from recent US political and economic developments, besides weak crop prices.
"There are legitimate reasons to be cautious, especially with the rising uncertainty in agricultural exports and likely rise in interest rates."
Indeed, many observers are expecting the Federal Reserve on Wednesday to raise the key US interest rate by 0.25 points, in the face of falling unemployment and firm US economic growth.
Furthermore, "there is a concern for some producers over possible financial difficulties due to continually declining income and accumulation of debt from banks and other sources".

"It is not unwarranted to be worried… Farmers and land owners who bet on the high commodity prices lasting and aggressively expanded or borrowed heavily will face significant problems."
Indeed, it looks like the correction in prices is not over yet, with Dr Zhang cautioning that "looking ahead, land values might continue to adjust downwards in the next year or two", a performance which would be "consistent with the stagnant corn and soybean futures prices and potential rise in interest rates".
Further price drops in 2017 and 2018 would see the current price retreat match, in terms of length, the decline in values in the 1980s, when Iowa prices dropping continuously from 1982-86.
However, in value terms, there was cause to believe that the current retreat will not match that of the 1982-86 period, during which Iowa prices slumped by 64%, in a decline fuelled by a sharp rise in interest rates at a time of elevated farm debts.
"Iowa farmland values do not appear to be in a speculative bubble that caused the dramatic declines in the 1980s farmland values or the urban real estate market in the mid-2000s," the university said.
"Farmers accumulated much more income, especially cash, during the most recent decade" than they did during the previous two "golden eras" for land prices, in the 1910s and 1970s.
"Farmers used to be able to borrow up to 85% of inflated, market-based land value in the 1970s, while now they can only get less than half of cash-flow based land values.
"It appears most farmers will be able to weather the storm as the market prices find a new equilibrium."
The likely outcome is that downward pressure on farmland values "will continue and play out next year and beyond, but it will more than likely be a rational and modest correction as opposed to a sudden change".
The current scenario appears more like the extended and relatively gentle drop in land values which started in 1921 and extended into 1933, in the midst of the Great Depression, than the "dramatic collapse" of the 1980s.
"We might see this farm downturn resemble the trajectory of the 1920s farm crisis in the sense that there might be a long, drawn-out decline in the farmland market."
