Iowa Crop Progress & Condition

Week of April 26 – May 2, 2021

Iowa Secretary of Agriculture Mike Naig today 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.

“The weather over the past several days provided a great window for farmers to plant,” said Secretary Naig. “Now we need some rain, especially in the northern parts of the state, to help push the crop along. Short-term outlooks are promising with the potential for cooler and wetter days ahead.”

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

Crop Report

Planting of corn and soybean crops accelerated during the week ending May 2, 2021, according to the USDA, National Agricultural Statistics Service. Statewide there were 6.3 days suitable for fieldwork for the week due to limited precipitation. Other field activities such as applying anhydrous and dry fertilizer were sporadic, due to strong winds.

Topsoil moisture levels rated 17% very short, 38% short, 45% adequate and 0% surplus. Subsoil moisture levels rated 14% very short, 44% short, 42% adequate and 0% surplus. Dry conditions are a concern. Iowa farmers were able to plant almost half of the State’s expected corn crop during the week ending May 2 for a total of 69% planted, 9 days ahead of the 5-year average. With the week’s warmer temperatures, there were scattered reports of corn emerged.

Iowa farmers planted over one-third of the expected soybean crop during the week ending May 2 for a total of 43% planted, 12 days ahead of normal. Ninety-five percent of Iowa’s expected oat crop has been planted, 2 days ahead of last year and 10 days ahead of the 5-year average. Statewide 51% of the oat crop has emerged, 3 days ahead of average.

Pasture condition rated 41% good to excellent. Reports were received of slow growth due to lack of moisture. No livestock problems were reported.

Unseasonably dry conditions persisted across Iowa during the reporting period with departures nearing an inch below average at multiple stations statewide. Only portions of extreme southeast Iowa reported above-average rainfall. Warm and windy conditions were also observed on multiple days with parts of western Iowa experiencing temperatures up to 10 degrees warmer than normal; the statewide average temperature was 62.0 degrees, 8.0 degrees above normal.

A disturbance moving through the Midwest brought showers across northern Iowa in the late morning hours on Sunday (25th) with rain exiting eastern Iowa in the evening. Strong southeasterly winds built-in as a low-pressure system approached from the west. Rain totals reported at 7 a.m. on Monday (26th) were highest in the northwestern corner with Sanborn (O’Brien) and Spirit Lake (Dickinson) observing 0.35 inch; totals tailed off south and east where rain gauges collected a few tenths of an inch. With a strong southerly wind persisting under mostly sunny skies, afternoon highs pushed into the mid to upper 80s in southwestern Iowa while cloud cover held temperatures in the 60s and 70s over northern Iowa. Morning lows on Tuesday (27th) remained unseasonably warm over the state’s southern half, generally in the low to mid-60s with upper 40s under cloud cover towards the Iowa-Minnesota border. A center of low pressure pushing through Iowa shifted winds to a northerly direction from the west to east during the day leading to quite a range of temperatures; low 50s were reported behind the low in northwestern Iowa and low to mid 80s behind the warm front in southern Iowa. Showers formed across western Iowa as the disturbance propagated over the region. Showers and a few thunderstorms continue to pop up through most of Wednesday (28th), leading to higher totals in southeastern Iowa as the system moved east. Event rain totals reported at 7 a.m. Thursday (29th) was highest in the state’s southeast corner with over 20 rain gauges collecting an inch or more of new rainfall; several stations in Appanoose, Davis and Lee counties observed more than 1.50 inches.

Behind the system, skies began to clear with a light northerly breeze and near-seasonal afternoon highs in the low to mid-70s. Skies remained generally clear with a few cumulus clouds passing through northern Iowa as the moon set Friday (30th) morning.  Temperatures climbed back into the 70s with variable winds, leading to a very pleasant day statewide. Overnight lows into Saturday (1st) remained warm, ranging from the mid-50s south to low 60s north. Blustery winds out of the southwest and clear skies led to the warmest temperatures of the season with mid to upper 90s in northern Iowa and mid-80s in southern Iowa; the statewide average high was 87 degrees, 20 degrees above normal. As the sunset, winds gradually died down under starry skies into Sunday (2nd) morning with observed lows in the upper 50s and low 60s.

Weekly precipitation totals ranged from no accumulation at several stations across Iowa to 1.72 inches at Rathbun Dam (Appanoose County). The statewide weekly average precipitation was 0.18 inch while the normal is 0.89 inch. Spencer Municipal Airport (Clay County) reported the week’s high temperature of 97 degrees on the 1st, 31 degrees above average. Elkader (Clayton County) reported the week’s low temperature of 24 degrees on the 26th, 15 degrees below normal. Four-inch soil temperatures were in the low to mid-60s statewide as of Sunday.

Iowa Crop Progress & Condition

Week of April 19 – 25, 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.

“We’ve seen improvement in drought conditions across western Iowa,” said Secretary Naig. “Colder temperatures and some late-season snow slowed farmers down last week. However, recent weather patterns have allowed more farmers to get into the fields and a warm and windy forecast should ramp up field activities in the coming days.”

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

Crop Report

Below normal temperatures during the week ending April 25, 2021 delayed planting for some farmers but as the weekend neared, planting accelerated according to the USDA, National Agricultural Statistics Service. Statewide there were 5.6 days suitable for fieldwork during the week. Field activities for the week included applying anhydrous and dry fertilizer, tilling fields and planting.

Topsoil moisture levels rated 6% very short, 28% short, 64% adequate and 2% surplus. Subsoil moisture levels rated 10% very short, 35% short, 54% adequate and 1% surplus.

Despite hesitancy due to cold soil temps, 20% of Iowa’s corn crop has been planted, one day behind the 5- year average. Some farmers chose to plant soybeans with 6% of the crop planted, 3 days ahead of normal. Eighty-three percent of Iowa’s expected oat crop has been planted, 3 days ahead of last year and 6 days ahead of the 5-year average. Statewide 29% of the oat crop has emerged, 3 days ahead of average.

Pasture condition rated 45% good to excellent. Calving is reportedly going well. Despite pasture and hay being slow to grow, cattle are on pastures.

A cold front swept through the state overnight into Monday (19th) bringing much cooler temperatures. Behind the front, rain switched over to snow during the morning hours with a rain and snow mix persisting over much of Iowa’s western half and along the Iowa-Missouri border. Light rain and some snow remained across southeastern Iowa on Tuesday (20th) morning with a majority of Iowa’s stations reporting a temperature below 32 degrees. Event snow totals reported at 7:00 am were generally under a half of an inch, though 10 stations reported an inch or more; Little Sioux (Harrison County) measured 2.7 inches while Sibley (Osceola County) reported 4.0 inches. Daytime temperatures rebounded into the mid to upper 40s with the statewide average high of 45 degrees, 18 degrees below normal. Iowa experienced another frosty morning on Wednesday (21st) with a vast majority of thermometers falling below 28 degrees, leading to a late-season freeze. With the sun shining and a southerly wind, warmer afternoon temperatures were observed, from the upper 50s to low 60s across the state.

High pressure built into the region Thursday (22nd) as southerly flow pushed daytime highs into the upper 50s and low 60s under sunny skies. Overcast conditions developed overnight into Friday (23rd) holding temperatures in the mind to upper 40s with some spotty light rain showers in western Iowa. Southerly winds increased over the late morning hours as a weak low pressure system sluggishly moved across northern Iowa, shifting winds to a northerly direction from west to east through the early morning hours on Saturday (24th). Starry skies were reported in the southern quarter of the state, while clouds remained over the rest of Iowa as the low’s attendant cold front propagated southeast. Lows reported at 7:00 am ranged from the upper 30s to low 40s with very light rain totals across southeastern Iowa. Clouds cleared in the west through the morning hours and sunny conditions advanced east through the evening. Daytime highs reached the low 50s north to low 60s south, still four to ten degrees below average. Clouds redeveloped in western Iowa ahead of disturbance into Sunday (25th) morning with reports of light rain and some snowflakes in the northwest corner; Orange City (Sioux County) observed 0.08 inch at 7:00 am.

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 nass.usda.gov.

Crop Report

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.

After a warm first half of April, cooler conditions were observed statewide over the reporting period with temperatures up to six degrees below normal; the statewide average temperature was 44.8 degrees, 4.5 degrees below normal. A less active storm track brought drier than normal readings to rain gauges across the state with departures of up to 0.80 inch in the northeast.

Rain showers finally exited eastern Iowa early in the afternoon on Sunday (11th) as skies continued to clear west to east. Daytime highs ranged from the mid 60s in southwest Iowa to low 50s in the east. Gusty westerly winds built in across the state on Monday (12th) under mostly sunny skies with afternoon temperatures reaching into the mid to upper 50s. Cloud cover increased overnight into Tuesday (13th) with lows hovering in the mid 30s to upper 30s where clouds were present; under clear skies, thermometers in southwestern Iowa registered readings in the low 30s. Windy conditions persisted through Wednesday (14th) as afternoon temperatures remain unseasonably cool; northern Iowa reported highs in the low to mid 40s under cloud cover while sunny skies in the south pushed temperatures into the mid 50s. Morning temperatures reported at 7:00 am on Thursday (15th) were at or below freezing across much of Iowa as a cold front dropped south through the state with the coldest readings in northern Iowa; the statewide average low was 30 degrees, seven degrees colder than normal. Afternoon conditions were generally overcast with a light northwesterly wind and temperatures in the upper 40s and low 50s.

Overnight lows into Friday (16th) remained above freezing across much of northern Iowa where cloud cover was present though some stations in southern Iowa reported readings below 32 degrees. Clouds and a light northerly wind held afternoon temperatures in the mid 40s and low 50s as an upper level disturbance approached from the west. Rain showers pushed into southwestern Iowa during the afternoon hours on Saturday (17th) as chilly conditions persisted across Iowa; temperatures only reached into the mid 40s over the state’s western half. Showers lingered over southern Iowa into Sunday (18th) with 24 hour rain totals reported at 7:00 am across the southern one-third of Iowa ranging from near 0.50 inch west to a little over 0.10 inch east.

Iowa Crop Progress & Condition

Week of April 5 – 11, 2021

“With spring weather now upon us, farmers across Iowa are looking to get planters into the field,” said Iowa Secretary of Agriculture Mike Naig in releasing the weekly Iowa Crop Progress and Condition Report. “Rainfall over the last week has been beneficial for the drier parts of the state, though farmers should keep an eye on the forecast, as freezing temperatures are possible over the next few days.”

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

Measurable rainfall fell across the State which allowed Iowa farmers only 3.1 days suitable for fieldwork during the week ending April 11, 2021, according to the USDA, National Agricultural Statistics Service. Fieldwork activities included applying anhydrous and fertilizer, spreading manure, spring tillage and planting oats. There were also scattered reports of corn being planted.

Topsoil moisture levels rated 4% very short, 17% short, 69% adequate and 10% surplus. Subsoil moisture levels rated 12% very short, 28% short, 56% adequate and 4% surplus.

Thirty-seven percent of the expected oat crop has been planted, 4 days ahead of last year and 5 days ahead of the 5-year average. Statewide, 3% of the oat crop has emerged.

Pasture condition rated 3% very poor, 11% poor, 42% fair, 40% good and 4% excellent. Pastures are greening up and starting to grow. Muddy feedlots were reported in the southern part of the state.

In the weekly weather summary provided by Justin Glisan, Ph.D., State Climatologist, Iowa Department of Agriculture and Land Stewardship, it was noted that a transition to an active storm track brought several waves of welcome rainfall across Iowa over the last seven days.

Slow-moving low-pressure systems with persistent, steady rain showers produced totals of up to three inches above normal in southeastern Iowa.  Cloud cover and rain could not keep temperatures down as unseasonable warmth blanketed the state during the reporting period; Iowa’s average temperature was 55.9 degrees, 10.9 degrees above normal.

Sunday (4th) afternoon was pleasant with sunny skies and southerly winds helping temperatures reach into the mid-70s east to mid-80s west. Spotty thundershowers popped up across northeastern Iowa during the late evening ahead of a low-pressure system. The disturbance brought rain showers over the northern half of the state through Monday (5th) afternoon with totals on the order of a few tenths of an inch. Afternoon highs returned to the upper 70s and low 80s as skies cleared and blustery southerly winds persisted. A line of strong thunderstorms pushed into extreme northwest Iowa during late evening and skirted the Iowa-Minnesota border into early Tuesday (6th) morning before dissipating in northeastern Iowa. Scattered showers and thunderstorms re-formed later in the day in advance of a surface boundary moving into western Iowa overnight into Wednesday (7th). As temperatures warmed into the 70s with ample low-level moisture, additional thunderstorms formed in south-central Iowa on the north side of  low-pressure center over northwestern Missouri. The storms, with locally heavy rainfall and small hail, moved north and east through late evening. Thunderstorms in eastern Iowa became stronger with a brief, weak tornado reported near Cedar Rapids (Linn County) that caused damage to several structures.

The disturbance continued to circulate additional waves of showers across the state as it propagated northeast through Thursday (8th). Two-day rain totals were highest across southern and western Iowa, with totals on the order of 0.75 inch to above an inch; multiple stations in south-central Iowa measured over two inches with Murray (Clarke County) observing 2.70 inches. All National Weather Service coop stations reported measurable rainfall with a statewide average of 0.69 inch. The low-pressure center continued to spin through the Great Lakes as rain showers gradually dissipated over Iowa on Friday (9th) morning. Overcast skies remained throughout the day with highs stuck in the mid-50s and a light northwesterly wind. Another center of low pressure propagated from Kansas into Missouri through the overnight hours into Saturday (10th). With a lack of upper-level steering flow, the sluggish low created a persistent rain shield across eastern Iowa. Western Iowa began to clear in late afternoon with temperatures reaching into the upper 50s and low 60s; under cloud cover and rain, eastern Iowa remained dreary and chilly with highs only in the mid to upper 40s. Overnight lows into Sunday (11th) dipped into the 30s in western Iowa while clouds held temperatures within the same range as late Saturday afternoon. Rainfall totals in Iowa’s eastern one-third were generally above 0.50 inch with over 20 reporting 1.00 inch or more; Keokuk Lock and Dam (Lee County) observed 2.76 inches.

Weekly rain totals ranged from 0.28 inch at Decorah Municipal Airport (Winneshiek County) to 4.42 inches Keokuk Lock and Dam. The statewide weekly average precipitation was 1.45 inches while the normal is 0.64 inch. Multiple western Iowa stations reported the week’s high temperature of 86 degrees on the 4th and 5th; on average 29 degrees above normal. Several northwestern Iowa stations reported the week’s low temperature of 28 degrees on the 11th, on average six degrees below normal. Four-inch soil temperatures were in the upper 40s east to low 50s west as of Sunday.
