Wisconsin: Corn Needs Heat to Promote Pollination – USDA
Crop Progress and Condition for the Week Ending July 13, 2014.
Wisconsin experienced yet another week with intermittent rainfall. Although there were a few days available for fieldwork mid-week, high moisture levels continued to slow field operations and stress crops in low-lying areas. Topsoil moistures declined overall, with 25 percent surplus on average compared to 30 percent last week.
Farmers were working to catch up on haying, herbicide application and nitrogen side-dressing. Second crop alfalfa progressed well, though drying hay continues to be problematic in some areas. Corn was beginning to tassel across the state, but reporters noted that more heat units are needed to promote pollination.
While the majority of both crops were in good condition, corn and soybeans in late-planted and moisture-stressed fields were still struggling to catch up. Crops from small grains to cranberries were in need of warmer weather to mature.
There were 4.6 days suitable for fieldwork statewide.
Across all reporting stations, average temperatures last week were near normal. Average high temperatures ranged from 79 to 82 degrees, while average low temperatures ranged from 59 to 63 degrees. Precipitation totals ranged from 0.23 inches in Green Bay to 3.51 inches in La Crosse.
As of July 13, five percent of corn was silking statewide. Corn condition was rated 77 percent good to excellent.
Soybeans were 24 percent blooming. One percent of the crop was setting pods, compared to 0 percent last year and a five year average of 1 percent. Soybeans condition was rated 74 percent good to excellent.
Oats were 90 percent heading and 36 percent turning color. Oats were 3 percent harvested for grain, compared with 2 percent last year and a five year average of 7 percent. Condition was rated 82 percent good to excellent statewide.
Seventy-nine percent of winter wheat was turning color, with 2 percent harvested. Seventy-three percent of the crop was in good to excellent condition.
Ninety-two percent of the potatoes were rated in good to excellent condition.
The first cutting of alfalfa was 97 percent complete and the second cutting was 44 percent complete.
All hay condition was rated 88 percent good to excellent.
Pasture condition was rated 92 percent good to excellent.
RUSK-G.P.: Corn and beans are looking OK, but cool weather for this time of year is slowing growth and putting an already late crop in even more danger of not maturing before first frost. Hay continues to be slow with some first crop still to be made and second crop not moving along very fast. Rain over the weekend has stalled things again with more rain predicted for Monday and highs not even getting out of the 60’s some days this week. Produce is slow to show up at the local farmers market.
SAWYER-K.S.: Spotty rains moved through this week. Some areas over 0.75 inch with small hail, no reported damage. Crops look very good, although their development is behind. Like the rest of the state our heat unit accumulation is 300 or more units behind normal. Getting row crops sprayed has been a challenge with rains.
CLARK-A.K.: Need sun and dry weather.
PRICE/TAYLOR-D.E.: Almost daily rain made it extremely difficult to do any type of field work. Some spraying got done but fields are muddy. Second crop hay is coming back very nicely.
MARINETTE-N.S.: More progress for the hay harvest over the weekend. A few areas received scattered rain showers during the week, while others received no rain. Corn on sandier ground looks the best at this point. Lower fields have some yellowing and growth is a little more uneven.
SHAWANO-B.R.: The second cutting of alfalfa is excellent in both quantity and quality for those that had the first cutting off on time. With all the wet weather, the winter wheat is starting to deteriorate. Disease is in most stands even if a fungicide has been applied. Still have many fields that need to be sprayed yet for weed control in the area.
MONROE-B.H.: The farthest along corn was just beginning to push tassels out over the weekend.
ST CROIX-D.K.: We continue to get good rain fall – probably too hard but better than not at all. Crops continue to look good except where they’ve drowned out early.
TREMPEALEAU-D.D.: Tassels are just beginning to emerge on a large number of acres in field corn. Rains keep coming, so second crop and small grain silage harvests are a challenge. No grain has been combined to my knowledge.
JUNEAU-J.W.: It was a good week. No bad weather, some rain, overall good weather and crops are doing well. Corn and soybeans really took off.
FOND DU LAC-B.B.: 0.70 inches rain for the period with average high temps of 76 degrees F. Allowed for some field work including harvest of some very good second crop hay, winter rye for forage and fertilizer/manure applications. Corn and beans in low ground still struggling to green up.
VERNON-K.L.: Rain continues and part of the county had some hail. Hard to make dry baled hay. Crops look good overall. Not too much complaining from farmers. Hard to spray due rainy days.
DANE-F.P.: Corn is not tasseling. Corn is from 3 to 8 feet tall. 3rd crop alfalfa looks good.
OZAUKEE-G.S.: We are taking a lot of prevent plant crop reports and seeing a few drowned out spots in low areas of fields, and the rain has made it difficult to make hay. Corn and soybeans are progressing, but could use some heat units.
WAUKESHA-R.F.: Corn is 4 feet tall. Very good weather this past week and should still be good next week.
