Iowa Crop Progress and Condition Report July 19 - 25, 2021


Iowa Secretary of Agriculture Mike Naig commented today 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.

“Warmer temperatures combined with a drier weather pattern moved into Iowa over the last week,” said Secretary Naig. “Forecasts show county fairgoers are going to experience hot temperatures as the heat wave continues across the state. We’re hearing about moisture stressed crops, especially in the drought region, so we’re keeping an eye on rain chances predicted over the weekend.”

Crop Report

Hot, dry conditions and minimal rain allowed Iowa farmers 6.4 days suitable for fieldwork during the week ending July 25, 2021, according to the USDA, National Agricultural Statistics Service. Field activities included applying fungicides and insecticides and harvesting hay and oats.

Topsoil moisture levels rated 14% very short, 39% short, 46% adequate and 1% surplus. Subsoil moisture levels rated 20% very short, 40% short, 39% adequate and 1% surplus. The shortage of moisture was especially evident in northwest Iowa, where topsoil was rated 70% short to very short and subsoil was rated 84% short to very short. In some parts of the State creeks have gone dry due to lack of rain.

The lack of precipitation is causing some stress on crops, especially in the northern third of the State. Corn silking or beyond reached 80%, equal to the 5-year average. Corn in the dough stage reached 21%, three days ahead of normal. Iowa’s corn condition was rated 65% good to excellent. There were scattered reports of corn in the dent stage. Eightyfive percent of soybeans were blooming, 6 days ahead of the five-year average. Over half of Iowa’s soybeans were setting pods, also 6 days ahead of normal. Soybean condition was rated 61% good to excellent. Oats coloring or beyond reached 94%, two days ahead of normal. Forty-eight percent of oats for grain have been harvested, 1 day ahead of the 5-year average. Iowa’s oat condition rated 64% good to excellent.

The second cutting of alfalfa hay reached 83% complete. The third cutting was reported at 8% complete, equal to the 5-year average. Hay condition rated 60% good to excellent. Pasture condition was rated 44% good to excellent. High temperatures and humidity are impacting livestock and some producers are still fighting pinkeye in cows and calves.

A transition to a less active storm track brought quieter conditions to Iowa during the reporting period with unseasonable dryness statewide; rainfall departures of near an inch were reported in northeastern Iowa. Hazy and warm conditions persisted as a stagnant pattern set up over the Midwest. Near-normal seven-day temperatures were reported in the southwest with positive departures of up to four degrees observed northeast; the statewide average temperature was 75.4 degrees, 1.2 degrees above normal.

Afternoon temperatures on Sunday (19th) stayed in the low to mid 80s across Iowa with partly cloudy skies and variable winds. Conditions into Monday (20th) morning were generally calm with isolated fog and widespread upper-level haze from western wildfire smoke observed over the Midwest. Temperatures ranged from the mid 50s northwest to mid 60s southeast with a statewide average low of 61 degrees, just two degrees below normal. Similar conditions continued into Tuesday (21st) with extremely isolated showers producing light rain in northern and eastern Iowa; only a few stations reported rainfall with a gauge near Center Point (Linn County) collecting 0.25 inch. Overnight lows stayed in the mid to upper 60s as another small area of light rain moved over northern Iowa. A southerly wind shift into Wednesday (22nd) allowed daytime highs to reach into the mid 80s across much of Iowa as gradual warming through the end of the week began. Skies remained clear overnight with a brilliant sunrise above a smokey horizon on Thursday (23rd). Sunshine and gusty southerly winds boosted highs into the upper 80s and low 90s through the day.

Cloud cover increased across northwestern Iowa in advance of a low pressure system moving through the Dakotas into Minnesota. The southern flank of the system brought showers through northern Iowa into Friday (24th) morning before dissipating in northeastern Iowa a few hours later. Rain totals were light with under 30 stations reporting measurable amounts; Sibley (Osceola) observed 0.24 inch while Everly (Clay County) only reported 0.01 inch. Partly cloudy skies gradually cleared in southeastern Iowa as a weak cold front dropped south across the state producing northerly winds and slightly lower humidity. Even with the passing boundary, high temperatures remained in the upper 80s and low 90s with a statewide average high of 90 degrees, six degrees above normal. As variable winds built-in overnight, a wide range of morning temperatures was reported at 7:00 am on Sunday (25th); Stanley (Buchanan County) observed 57 degrees, two degrees below average, while 74 degrees was reported at Keokuk Lock and Dam (Lee County); this reading was seven degrees above average.

Weekly precipitation totals ranged from no accumulation at most of Iowa’s reporting stations to 0.64 inch at Swea City (Kossuth County). The statewide weekly average precipitation was 0.02 inch while the normal is 0.93 inch. Corning (Adams County) and Sioux City Airport (Woodbury County) observed the week’s high temperature of 96 degrees on the 24th, on average 11 degrees above normal. Spencer Municipal Airport (Clay County) reported the week’s low temperature of 54 degrees on the 19th, nine degrees below normal.
