Most of Iowa’s soybean crop still in field

TOO MUCH RAIN: Iowa’s 2018 soybean crop is running into quality problems, as persistent rains have swamped an increasing number of fields.
Wet fall is causing the slowest soybean harvest on record in Iowa, as crop conditions deteriorate.

Cool, wet weather kept Iowa farmers mostly out of the fields last week. As a result, they were only able to harvest 2% of the corn and 1% of soybean acres. Corn harvest is now four days behind average, and soybean harvest is running 11 days behind, according to the latest weekly USDA survey.

With just 19% of Iowa’s 2018 soybean crop harvested as of Oct. 14, farmers this year are having the slowest bean harvest on record for Iowa. The weather has been so wet in recent weeks that soybeans in some fields are sprouting in the pods.

Harvest is expected to resume this week, looking at the weather forecast. “With dryer weather in the forecast, farmers will be putting in long hours to bring in the crop as quickly as possible when conditions allow,” notes Iowa Secretary of Agriculture Mike Naig. “We encourage everyone working on the farm or traveling on rural roads to remember to take the time needed to be safe during what can be a very busy and stressful time.”

Iowa farmers have only 17% of the state’s 2018 corn crop harvested vs. 24% for the five-year average at this time. Nebraska farmers have 25% of their corn out of the field, equal to their five-year average.

Corn-producing states in the eastern Corn Belt are way ahead of the western Corn Belt. Illinois has 71% of its corn harvested vs. a 54% five-year average; Indiana has 51% harvested vs. a 39% five-year average. The national corn harvest is 39% complete as of Oct. 14, says USDA, slightly ahead of the five-year average of 35%.

Rain and early snow showers limited Iowa farmers to just 0.8 day suitable for fieldwork during the week ending Oct. 14, according to USDA’s National Ag Statistics Service. Activities for the week included moving grain, monitoring field conditions and harvesting corn when weather permitted.

Topsoil moisture levels rated zero percent very short, zero percent short, 40% adequate and 60% surplus. Subsoil moisture levels rated 1% very short, 2% short, 49% adequate and 48% surplus.

Statewide, 97% of the 2018 Iowa corn crop has reached maturity mature, five days ahead of the five-year average. Of the state’s corn for grain crop, 17% has been harvested as of Oct. 14, which is four days ahead of last year but four days behind average.

Across the Iowa farmers were only able to harvest 2% of their corn for grain crop last week. Farmers in southeast Iowa continue to lead the way with 41% of their corn harvested. Moisture content of field corn being harvested in Iowa is at 20%. Corn condition is rated 69% good-to-excellent.

Iowa’s soybean crop is 97% dropping leaves, five days ahead of average. And 19% of the soybean crop has been harvested, 11 days behind the average. This is the smallest percentage of the soybean crop harvested by Oct. 14 since records began. Soybean condition is rated 65% good-to-excellent.

Pasture conditions are 55% good-to-excellent for the statewide average. Livestock conditions remain challenging after another week with significant rainfall leaving feedlots extremely muddy.
