Iowa Crop Progress and Conditions Report

By Staff | Jun 7, 2019

DES MOINES – Iowa Secretary of Agriculture Mike Naig has 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.

“It has been another challenging week weather-wise for farmers across the state,” said Secretary Naig. “With just 1.3 days suitable for fieldwork, the historic planting delays continue. The corn planting progress is now nearly three weeks behind the five-year average, and soybean planting progress is 18 days behind last year and the five-year average. This coming week is critical for farmers who are making tough planting decisions. If we can get a stretch of warm, dry days, farmers can make significant gains.”

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

Crop report

Iowa farmers continue to battle wet field conditions as another week of heavy rainfall limited farmers to only 1.3 days suitable for fieldwork statewide during the week ending June 2, according to the USDA, National Agricultural Statistics Service. The lower third of Iowa had 0.5 day suitable for fieldwork or less for the second week in a row.

Topsoil moisture levels rated 0 percent very short, 0 percent short, 50 percent adequate and 50 percent surplus. Subsoil moisture levels rated 0 percent very short, 0 percent short, 49 percent adequate and 51 percent surplus.

Eighty percent of the expected corn crop has been planted, nearly 3 weeks behind the 5-year average. This is the smallest amount of corn planted by June 2 since 1982 when 76 percent of the expected crop had been planted. There were comments that some of these expected corn acres may go to soybeans or prevented planting. Fifty-eight percent of the crop has emerged, 12 days behind last year and 13 days behind average.

Forty-one percent of the expected soybean crop has been planted, 18 days behind last year and average. This is the smallest percent of soybeans planted by June 2 since 1993 when just 39 percent of the expected crop had been planted. Seventeen percent of the crop has emerged, 2 weeks behind last year and 13 days behind average. Ninety-three percent of the expected oat crop has emerged, 8 days behind last year and 10 days behind average. Six percent of the crop has headed, 8 days behind average.

Only 4 percent of the State’s first cutting of alfalfa hay has been completed, over two weeks behind average. Hay condition rated 60 percent good to excellent. Pasture condition decreased slightly to 62 percent good to excellent. Feedlots remain muddy.

Iowa continued to experience wetter than normal conditions as a persistent weather pattern locked in over the Midwest brought multiple low pressure systems through the state. Temperatures were near normal across a majority of Iowa with cooler conditions in northwestern Iowa and slightly warmer conditions in parts of eastern Iowa.

After an unseasonably warm and sunny afternoon, thunderstorms moved through Iowa late Sunday, May 26th night through Memorial Day. Isolated severe thunderstorms moved through west-central Iowa early in the day with reports of straight-line wind damage to trees from Page County to Polk County; 70 mph wind gusts were reported in Menlo.

Around mid-afternoon, an isolated severe storm in northeastern Iowa produced multiple reports of tornadoes from Charles City into Howard County. Weak tornadoes with minor structural damage were also reported across Van Buren, Des Moines, and Lee Counties, associated with a fast moving severe storm in the evening hours.

Tuesday, May 28th, was another active day with additional rounds of thunderstorms moving through the state. There were also severe hail and high wind reports across southern Iowa; wind damage was reported to multiple structures at an Iowa State University research farm in Lucas County.

Two-day rain totals were largest across the state’s southern third where multiple stations reported above average totals between two to four inches. Over 40 stations reported totals above two inches with Salem observing 4.70 inches. Rainfall totals across the rest of Iowa were generally between 0.50-1.00 inch.

A low pressure system located in eastern Nebraska slowly propagated through Iowa on Wednesday, May 29th, spinning up weak land spout tornadoes in nine counties. Structural and tree damage was reported along with one injury in Poweshiek County. Strong thunderstorms formed later in the day across eastern Iowa, producing locally heavy downpours.

Parkersburg reported 1.35 inches, 1.19 inches above average. The low finally exited on Thursday producing very isolated and slow moving storms in western Iowa.

Rainfall ranged from 0.10 inch in Rockwell City to 0.53 inch in Creston.

Last Friday was the week’s warmest day, especially in north-central Iowa, where highs were 10-12 degrees above average. Spotty thundershowers developed during the evening hours though they quickly dissipated. Another line of showers and thunderstorms sped through Iowa in the early morning hours on Saturday.

Rainfall totals were generally light with Atlantic reporting 0.42 inch. The rest of Saturday was relatively quiet statewide with highs reaching into the low to mid 70s across the state’s northern half and into the low 80s across southern Iowa, a few degrees warmer than average. Overnight lows into Sunday, June 2nd were generally in the mid to upper 50s. These readings were cooler than average, especially under clear skies.

Weekly rainfall totals ranged from 0.51 inch in Webster City to 5.14 inches in Keosauqua.

The statewide weekly average precipitation was 2.11 inches, while the normal is 1.08 inches. Temperatures averaged 64.8 degrees, 0.10 degree below normal.
