Nearly half of Iowa’s 2019 oat crop has now been planted, but not enough corn to show up in USDA’s statewide survey for the week ending April 21.
Mostly dry conditions, with spotty rains and warmer temperatures, allowed many farmers to get into the field last week. With favorable weather conditions ahead in the forecast, Iowa farmers will hopefully to make measurable progress this week.

It was mostly a dry week with spotty rains throughout Iowa during the week ending April 21, according to USDA’s National Agricultural Statistics Service. Statewide there were 4.1 days suitable for fieldwork, two more days than the previous week. Warmer temperatures and drier conditions increased fieldwork activities that included anhydrous and fertilizer applications, tillage, seeding oats, and planting of corn.
Topsoil moisture levels rated 0% very short, 1% short, 75% adequate and 24% surplus. Subsoil moisture levels rated 0% very short, 0% short, 65% adequate and 35% surplus.
The survey shows 48% of Iowa’s expected oat crop for 2019 has been planted, six days ahead of last year, but five days behind the five-year average. Less than a quarter of the expected oats have been planted in northwest and north-central Iowa, while all the other crop reporting districts had at least 25% increases in their expected oats planted.
Pasture condition rates 3% very poor, 8% poor, 36% fair, 44% good and 9% excellent. Pastures continue to green gradually, and there were few comments of cattle being turned out to pastures as grazing may hurt the already slow growth. Warmer temperatures have improved livestock conditions and helped dry out feedlots.
