ST. PAUL (AP) - Minnesota farmers who've had trouble completing their spring planting due to a muddy May are facing some important decisions this month.

About 1.2 million acres of corn has yet to be seeded, and nearly half the state's soybean acres have yet to be planted.

Two successive weeks of cold, wet weather put the brakes on what was rapid planting progress across Minnesota. Southeastern Minnesota has been particularly wet, and there's more rain in the forecast for most of this week.

University of Minnesota experts say that if corn isn't planted by June 10, farmers should give up on it, while soybean farmers should switch to lower-yielding short-season hybrids after that date.

Grain prices are rising as traders worry that yields will be hurt by the late finish to planting.
