Iowa Crops & Weather Report – April 19

DES MOINES, Iowa (April 19, 2021) – Iowa Secretary of Agriculture Mike Naig today commented on the Iowa Crop Progress and Conditions report released by the USDA National Agricultural Statistics Service. The report is released weekly from April through November.

“After soil temperatures warmed for several days, some farmers were able to start planting this past week,” said Sec. Naig. “With late-season snowflakes flying in parts of the state today and freezing temperatures expected early this week, farmers should continue to be cautious about planting.”

The weekly report is also available on the USDA’s website at

Snow and abnormally low temperatures meant farmers were not planting row crops for most of the week ending April 18, 2021, according to the USDA, National Agricultural Statistics Service. Statewide there were 4.7 days suitable for fieldwork during the week. Field activities for the week included applying anhydrous and dry fertilizer, spreading manure, tilling fields and planting.

Topsoil moisture levels rated 6% very short, 23% short, 67% adequate and 4% surplus. Subsoil moisture levels rated 10% very short, 32% short, 54% adequate and 4% surplus.

Although most Iowa farmers continued to wait for warmer temperatures, 4% of Iowa’s corn crop has been planted. Nearly two-thirds of Iowa’s expected oat crop has been planted, 5 days ahead of last year and 6 days ahead of the 5-year average. Statewide 12% of the oat crop has emerged, 2 days ahead of average. There were scattered reports of soybeans planted.

Pasture condition rated 47% good to excellent. Some cattle have already been moved to pasture.
