Seed corn, soybean harvest beginning

Sep 13, 2018

DES MOINES — With another week of widespread rainfall, Iowa farmers had just 2.1 days suitable for fieldwork during the week ending Sunday, Sept. 9, according to the USDA, National Agricultural Statistics Service.

The report is available on the Iowa Department of Agriculture and Land Stewardship’s website at www.IowaAgriculture.gov or on USDA’s site at www.nass.usda.gov/ia.

According to the report summary, activities for the week included harvesting seed corn, chopping corn silage and moving grain.

Topsoil moisture levels rated 1 percent very short, 3 percent short, 65 percent adequate and 31 percent surplus. Subsoil moisture levels rated 2 percent very short, 7 percent short, 67 percent adequate and 24 percent surplus. Drought concerns in south central and southeast Iowa were eased after recent storms lifted adequate to surplus topsoil moisture ratings to 75 percent or greater.

Ninety-eight percent of the corn crop has reached the dough stage or beyond with 87 percent dented or beyond, a week ahead of the five-year average. Twenty-eight percent of the corn crop was mature, also one week ahead of average. Corn condition rated 73 percent good to excellent.

Fifty-eight percent of the soybean crop was coloring with 17 percent dropping leaves, five days ahead of average. Soybean condition rated 72 percent good to excellent.

Despite limited days suitable for fieldwork, there were a few reports of both corn for grain and soybeans being harvested.

The third cutting of alfalfa hay was 83 percent complete, more than a week behind the previous year as weather conditions continued to slow progress.

Pasture conditions improved to 50 percent good to excellent. Heavy rains made feedlot conditions challenging for cattle producers.
