DES MOINES, Iowa (AP) — The corn harvest is 88 percent complete in Iowa, about 8 percentage points ahead of normal and soybeans are 98 percent done, three days ahead of average. Iowa Secretary of Agriculture Bill Northey says farmers finished with harvest have begun fall field work including tilling, fertilizer applications, and conservation practice construction.

He says the 12 percent of the corn crop still in the field represents an estimated $1 billion worth of grain yet to be harvested in Iowa. Much if it is showing high moisture levels and may require drying before it’s marketed. Iowa is on track for a 2.2 billion bushel corn crop, up 18 percent from last year.

Soybean production is estimated at 415 million bushels, slightly above last year’s 414 million bushels.
