Minnesota trend-line soybean yields in 2015

MN soybean yields 1985 2015

What can we expect for soybean yields in Minnesota in 2015? Extending the trend over the past 30 years indicates a trend-line yield of 43.5 bu./acre. The record for Minnesota soybean yields was set 10 years ago, when the state average 45.5 bu./acre in 2005. It is interesting to note that in 5 of the last seven years, Minnesota had below trend yields. Oddly enough, 2012 was one of the two years when yields were above trend – a year noted for its butt-kicking drought throughout the rest of the Corn Belt.

Note the slope of the trend-line, 0.333X. It’s another way of saying that Minnesota soybean yields have been improving by an average of 1/3 bu./year over the last 30 years.
