North Dakota cropland values increased by about 42 percent during 2012, according to Andrew Swenson, North Dakota State University Extension Service farm management specialist.
His estimate is derived from the published results of a January 2013 county- level survey commissioned by the North Dakota Department of Trust Lands. The 42 percent increase is similar to the 46 percent increase reported by the North Dakota Chapter of the American Society of Farm Managers and Rural Appraisers.
"The question is whether this huge increase has capped a 10-year rise in land values, which has been the largest in the past 100 years, even exceeding what occurred from 1973 to 1981," Swenson says. "North Dakota cropland values are now the highest ever, even when adjusting for inflation."
The drivers that have pushed land values have been well-documented. Grain prices from 2007 to the present have been much higher than any year prior to 2007.
Also, yields generally have been strong. For example, the three highest wheat yields ever have occurred within the past four years. This combination has provided several years of strong profit for crop producers, which has fueled their financial ability and desire to buy land.
Swenson believes 2012 was the apex in North Dakota crop production profit because stored soil moisture provided much better yields than expected. At the same time, prices soared due to a drought in the Corn Belt.
A factor that has been just as important in driving land values has been low interest rates.
Interest rates to finance land purchases are attractive, while returns and confidence on alternative investments have been weak.
Ten years ago, an acceptable return on land investment (cash rent minus real estate taxes divided by land value) was about 6 percent. Now it is about 3 percent. If buyers insisted on a return of just one percentage point more, to 4 percent, land values would have to drop by one-fourth, assuming constant cash rents and real estate taxes.
If a general rise in interest rates occurs, being able to cash flow land purchases with debt capital becomes more difficult. Also, certain fixed-return investments may become more attractive relative to investing in land.
"This perfect storm of high crop prices and yields and low interest rates driving land values higher will not continue indefinitely," Swenson says. "In fact, there are strong indications that 2013 crop prices will be significantly lower than in 2012. In addition, government subsidies for agriculture are expected to diminish, if not in 2013, then most certainly in 2014."
