READY TO GO: “We finally saw the sun the past two days and that was the first time in a while,” says Harry Johannes, who was applying anhydrous in eastern Iowa on April 10. His Jackson County farm had almost 2 inches of rain and constant cloudy weather last week.

Iowa fieldwork gets going, fertilizer applications being made

Corn planters will start to roll across Iowa with drier, warmer weather this week.

Wet weather kept farmers from the field for most of last week across Iowa, but the drier weather and warmer temperatures late in the week did allow some fieldwork and fertilizer applications to take place. USDA’s weekly Iowa Crop Progress & Weather Report for the week ending April 9 showed some nitrogen as well as dry fertilizer was applied.

“We will need some more warm and dry weather before we start to see widespread fieldwork,” observes Iowa Secretary of Agriculture Bill Northey. “We are also seeing very good spring growth of the cover crops that were planted last fall. We will be highlighting information about cover crops on the Iowa Department of Agriculture’s social media sites all this week. We encourage farmers to share photos of cover crops on their farm.”

The complete weekly report is available on the Iowa Department of Agriculture & Land Stewardship website, IowaAgriculture.gov, or on USDA’s site, nass.usda.gov/ia. Following is the crop report’s summary along with the preliminary summary by state climatologist Harry Hillaker with the Iowa Department of Agriculture and Land Stewardship.

Summary of crop report
Rain prevented fieldwork early in the week ending April 9, but by the weekend many Iowa farmers were able to get into their fields, according to USDA’s National Agricultural Statistics Service. Statewide there were 1.8 days suitable for fieldwork. Activities included anhydrous ammonia, dry fertilizer and manure applications. There was some burning of Conservation Reserve Program groundcover as part of mid-contract management. Where conditions allowed, field cultivation took place. Farmers also prepared equipment for planting as they waited for the soil to warm up and dry out.

Across Iowa, topsoil moisture rated 1% very short, 3% short, 72% adequate and 24% surplus. Subsoil moisture rated 1% very short, 5% short, 75% adequate and 19% surplus.

Iowa’s 2017 oat crop is now 17% planted, based on planting intentions. This is just over one week behind the five-year average. Oat acres that have been planted and are emerged reached 4%, three days behind average.

Pasture condition rates 3% very poor, 7% poor, 27% fair, 54% good and 9% excellent. Pastures are beginning to green up as temperatures rise. Calving continues with no reported issues. Feedlots remain muddy, but conditions are improving.

Weather summary for Iowa
