Iowa Crop Progress & Condition Report

Week of Nov. 16-22, 2020

DES MOINES, Iowa (Nov. 23, 2020) – Iowa Secretary of Agriculture Mike Naig today commented on the Iowa Crop Progress and Condition report released by the USDA National Agricultural Statistics Service. The report is released weekly from April through November.

“Farmers have capitalized on the mild and dry weather over the past few weeks to wrap up harvest and complete other fieldwork, including seeding cover crops and installing other conservation practices,” said Secretary Naig. “This growing season has been challenging, no doubt. But Thanksgiving is the perfect opportunity for us to evaluate the positive food security initiatives and conservation work happening around the state. We all have so many things to be grateful for. Let’s take some time to count our blessings this week.”

The weekly report is also available on the USDA’s site at nass.usda.gov/ia.

Crop Progress

Dry conditions and warmer temperatures allowed Iowa farmers 6.3 days suitable for fieldwork during the week ending November 22, 2020, according to the USDA, National Agricultural Statistics Service. Fieldwork activities included harvesting corn for grain, baling corn stalks, applying fertilizer and manure, and hauling grain to elevators. Farmers in some areas of the State continue to clean up debris from the derecho that blew through in August.

Topsoil moisture condition rated 13% very short, 31% short, 56% adequate and 0% surplus. Subsoil moisture condition rated 22% very short, 35% short, 43% adequate and 0% surplus.

Only 2% of Iowa’s corn for grain crop remains to be harvested, over 3 weeks ahead of last year and 11 days ahead of the 5-year average. In most areas of the State only scattered fields remain to be harvested. Some corn fields damaged by the derecho remain to be disked down. Extra tillage is being done by some farmers out of concern for volunteer corn in 2021 due to damaged corn this crop year.

No problems with livestock were reported. Livestock producers continue to allow cattle to graze on corn stalks. Some producers are providing supplemental feed for cattle on pastures.
