8 2 Crop Progress Review of 2017 Derived from USDA NASS reports on December 27, 2017 and January 18, The 2017 crop season opened with widespread concern for overwintered crops. This was due to unusually warm weather in February followed by low snow cover and fluctuating temperatures in March. Waterlogged soils and frequent rains left a total of 10.4 days suitable for fieldwork in the month of April. Early May saw a window of drier conditions, allowing spring fieldwork to surge before heavy rains, flooding, and severe storms stalled fieldwork mid month. Continued wet conditions caused planting to drag on through May and well into June. Reporters noted some fields were drowned out or washed away by the frequent rains, forcing farmers to replant. Wet conditions also delayed or prevented weed control and nitrogen applications in some areas. This difficult start affected crops throughout the summer, with crop conditions mixed and crop development trailing behind the 5 year average statewide. June and July were very wet; frequent rains, flooding and severe thunderstorms damaged some crops, and prevented timely haying in many areas. Below normal temperatures in August and early September kept crop development behind average. Unseasonably warm and dry weather in late September helped to push late planted crops toward maturity and dried out the soil for fieldwork; although tillage and planting activities continued to trend behind normal throughout the fall. October brought even more rain and a return of soggy field conditions with temperatures swinging between summer like and wintry. Some areas of northern Wisconsin received their first frost during the week ending October 15 and a hard freeze hit statewide during the week ending October 29. Drizzle, fog and overcast skies kept grain moistures high throughout November, especially in late planted crops. Fall tillage was 68 percent complete on November 26, well below 85 percent complete the previous year. Statewide, February temperatures averaged 8.2 degrees above normal while March temperatures averaged 0.4 degree below normal. April, September and October had above normal temperatures; June and July had averages within 1 degree of normal; while May, August and November had below normal temperatures. The average temperature for June through September was 65.2 degrees, compared with 67.0 degrees in 2016 and a normal of 64.9 degrees. The statewide precipitation total for April through September was inches, 1.08 inches less than the previous year but 3.51 inches more than normal. Statewide, September and November had below normal precipitation. July precipitation totals ranged from 1.41 inches below normal in the North Central District to 3.76 inches above normal in the Southwest District. August precipitation ranged from 2.67 inches below normal in the Southwest District to 1.84 inches above normal in the Northwest District. April, May, June, and October had above normal precipitation across the state. Corn Cold, wet soils delayed the beginning of corn planting in Only one percent of corn was planted by April 23, about a week behind the 5 year average. Wet conditions kept planting and emergence behind average throughout May and into June. The wide variation in planting dates resulted in a persistent variation in crop condition and maturity among corn fields. Corn condition averaged 69 percent good to excellent for late May through mid November, compared with 86 percent good to excellent in Corn pollination and development remained behind the 5 year average throughout the summer. Dry, hot weather in the latter half of September helped boost the crop toward maturity before the first frost hit. Silage chopping got off to a late start due to lagging corn maturity, and wrapped up in early November, about a week behind average. Rain, fog and damp weather kept grain moistures high in late fall. Reporters noted many farmers were delaying grain harvest in an attempt to minimize drying costs. On November 26, 81 percent of corn for grain was harvested compared with 95 percent in Corn for grain production in Wisconsin during 2017 is estimated at 510 million bushels. This estimate is up 3 percent from the November 1 forecast but down 11 percent from Wisconsin's corn for grain yield is estimated at 174 bushels per acre, 6 bushels above the November 1 forecast. Area harvested for grain is estimated at 2.93 million acres, down 20,000 acres from the November 1 forecast and 290,000 acres below Corn planted for all purposes in 2017 is estimated at 3.90 million acres, equal to the November 1 estimate but 150,000 below Corn for silage production is estimated at 16.7 million tons, up 1 percent from The silage yield estimate of 19.0 tons per acre is 2.0 tons lower than

9 Producers harvested 880,000 acres of corn for silage, an increase of 90,000 acres from Soybean Like corn, soybean planting also started around a week behind the 5 year average, and suffered from weather delays. Warm weather in July kept soybean pollination in line with the 5 year average. Cooler temperatures in August slowed progress, but summerlike temperatures in late September gave soybean maturity a chance to catch back up. Soybean condition averaged 74 percent good to excellent for June through mid October, compared with 85 percent good to excellent for the previous year. The soybean harvest dragged on through variable fall conditions and high grain moistures, reaching 96 percent harvested on November 26. Soybean production is estimated at 101 million bushels in 2017, up 2.14 million bushels from the November 1 forecast but 6 percent below Wisconsin soybean growers aver aged 47.0 bushels per acre in 2017, up 1 bushel to the November 1 forecast but 8 bushels below the 2016 yield. The harvested acreage of 2.14 million is unchanged from the November 1 estimate but 190,000 acres above Soybean planted acreage, at 2.15 million acres, is up 10 percent from Soybean planted and harvested acreage set new record highs. Oats Oats planting lagged slightly behind the 5 year average due to a lack of days suitable for fieldwork in April, with variations in planting dates similar to other crops. Wet conditions and cool temperatures slowed oat maturity throughout the summer, particularly as the crop ripened in August. Oat condition averaged 77 percent good to excellent from May through mid August, compared with 85 percent the previous year. Oats reached 98 percent harvested on September 17. Early growth during March s warm spells started pastures off in above average condition. On April 9, 45 percent of pastures were in good to excellent condition, slightly below the 48 percent good to excellent the previous year but well above the 5 year average of 32 percent. Abundant precipitation kept pastures in good shape throughout the summer months, but condition declined during dry weather in early fall. On average, 72 percent of pastures were in good to excellent condition from May through October, compared with 76 percent in Winter wheat Winter wheat started April with 54 percent of the crop in good to excellent condition, well below the 79 percent the previous year. Wheat condition improved gradually through the summer months but remained below the 2016 average. Condition peaked at 79 percent good to excellent on July 30, with an average of 70 percent good to excellent for April through early August. Wet and cool conditions slowed maturity and harvest operations, with most of the crop being harvested in the last week of July and the first week of August. Winter wheat planting trended ahead of the previous year, as many farmers opted to plant wheat while waiting for corn grain moistures to fall. Bouts of sunny, warm weather promoted strong emergence and good growth before dormancy. Winter wheat averaged 84 percent good to excellent from mid October through the end of November, compared with 82 percent good to excellent in Alfalfa and Hay As of May 21, winter freeze damage to alfalfa was rated 5 percent severe, 10 percent moderate and 26 percent light. There were reportedly no damages to the remaining 59 percent of hay stands, down from 77 percent undamaged the previous year. The first cu ng of hay was delayed but rapidly caught up to and moved ahead of the 5 year average during early June. Cool temperatures and frequent rains throughout the spring and summer meant abundant hay but few windows of good weather for baling. Reporters commented producers were making more haylage than usual in an effort to harvest forage at optimal maturity. Dry, warm weather in September offered excellent conditions for making dry hay, allowing the fourth cu ng to exceed the average harvest pace. Abundant moisture and some above normal temperatures during October and November left hay stands in good condition to overwinter. Hay condition was 77 percent good to excellent on average for May through mid September, compared with 87 percent good to excellent in All hay production for the state is estimated at 3.48 million tons, down 11 percent from 3.93 million tons in Producers averaged 2.78 tons per acre, down from 2.95 tons per acre in All hay harvested acres are estimated at 1.25 million acres, down 80,000 acres from Alfalfa and alfalfa mixtures production is estimated at 2.58 million tons, down 19 percent from 3.20 million tons in Producers averaged 3.00 tons per acre, down from 3.20 tons per acre in Harvested acres, at 860,000, were down 140,000 acres from Wisconsin producers seeded 300,000 acres of new seedings of alfalfa and alfalfa mixtures in 2017, down 20,000 from the previous year. Other hay production is estimated at 897,000 tons, 24 per cent above Producers averaged 2.30 tons per acre, up from 2.20 tons per acre in Harvested acres of other hay, at 390,000, were up 60,000 acres from the previous year.
