ST. PAUL — Another week of above-average temperatures and limited rain helped Minnesota crops mature and let farmers make rapid harvest progress.

But the U.S. Department of Agriculture, in its weekly crop weather report Monday, also warns of precipitation shortfalls in the southern third of Minnesota. Topsoil moisture was rated 7 percent very short, 22 percent short, 64 percent adequate and 7 percent surplus, a decline from a week ago.

Spring wheat was 77 percent harvested, surpassing the five-year average of 76 percent. Oats were 90 percent harvested, compared to a 91 percent average, while barley was 76 percent harvested, compared with an 83 percent average.

Corn condition ratings were 24 percent fair and 51 percent good, a slight decrease. Soybean condition ratings fell slightly to 26 percent fair and 50 percent good.
