Soybean maturity has advanced rapidly in Minnesota over the past week, but still lags behind the normal pace. The US Department of Agriculture says that 40% of Minnesota’s soybean crop has reached maturity. That compares with a normal rate of 66% by this time of year. But it’s a big advance from last week, when only 9% of soybeans were mature. 93% of the soybean crop was turning yellow or beyond, six days behind normal. Soybean harvest has begun, and is 9% complete. Minnesota’s corn crop is also behind in development. The USDA says 41% of Minnesota’s corn is now mature, compared with 98% at this time last year. Corn and soybean crop conditions both declined slightly last week to 48% good or excellent.
