It was so bad that the sidewalk was slimy. Does anyone know if the soil will have to be replaced entirely? If so, how far down? Thanks http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3770 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3770 Fri, 14 May 2004 12:00:00 CST The rain just keeps on coming after a previous week of hard tillage and planting. The value of grass waterways and crop residue has never been more apparent. The pictures depict a field that was once farmed in strips but has since been converted to one large field with no measures taken to stop or slow erosion. Unfortunately, the field lies along the east side of Lake Winnebago (culvert in picture goes under the state Hwy. that runs along the lake). http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3210 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=3210 Thu, 14 Nov 2002 12:00:00 CST While traveling down to the Agronomy Meetings in Indianapolis, one couldn't help but notice several LARGE dairy operations just south of the Chicago Metro area along I-65 in Indiana. Of interest is the extensive use of 1)cover crops and 2)soil diking that is prevalent around the perimeter of fields near these dairies (presumably a runoff prevention mechanism). Not sure if either or both is a)legistated or b)voluntary. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2750 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2750 Thu, 13 Jun 2002 12:00:00 CST This field was seeded to alfalfa last summer following removal of fill for State Highway 29 construction. Erosion began last fall in areas where alfalfa did not catch. Oats were seeded this spring to help control erosion. Heavy rains this spring increased eroded area. Are there any suggestions for repairing the deeper eroded areas or should these areas constitute a future waterway? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2710 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2710 Mon, 10 Jun 2002 12:00:00 CST Corn emergence in +60% soybean residue. About 33,000 ppa. No alterations made to corn planter. No fall tillage and no till corn. A good residue spread off the combine. Would have thought a fluted coulter was needed but not in this case.

Manitowoc County photos, 5/23/2002 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2451 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2451 Mon, 20 May 2002 12:00:00 CST A visual difference of spring vs. fall tillage on soybean residue. This is one of the fields in the Team Grains tillage study. Other than increased residue, no real difference in seed bed condition. At another site, the contrast in residue after planting was less. If nothing else, this study will point out that it's very difficult to maintain 20 percent residue after planting regardless of when the tillage is done and what tool is used. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2412 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=2412 Thu, 16 May 2002 12:00:00 CST Third year of no-till. Interesting how residue begins to accumulate. About 47% residue. Fluted coulters on planter. Are row clearing devices needed (i.e. slow growth syndrome) ? My guess is not. Manitowoc County photos, 5/16/02. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=520 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=520 Wed, 02 May 2001 12:00:00 CST One of the historical problems to adopting mulch tillage has been problems with spring tillage. If fall chisel plowing was poorly done, field cultivating in spring can result in trash plugging. Particularly so with older, low clearance field cultivators. Newer field cultivators (as shown) have more vertical clearance, length and rows of tillage equipment. Additional comment welcome.Manitowoc County photo, 5,2,01. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=360 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=360 Fri, 11 Aug 2000 12:00:00 CST Manure on wheat stubble is a popular practice this time of year. Pits are near full and wheat ground offers an excellent option to stretch storage capacity. My sense is that we should offer a reminder regarding prompt incorporation to minimize surface water pollution potential. Not aware of any other drawbacks to this practice. Comments appreciated. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=349 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=349 Wed, 02 Aug 2000 12:00:00 CST Example field illustrates use of Poast Plus herbicide to contol oat companion crop on an erosion prone field. Alfalfa seeding is excellent and should produce forage yield comparable to direct seeding. Cost of companion crop plus the herbicide is the drawback. A dollar figure on the potential value of soil loss from significant rainfall events with a direct seeding in early spring would be of interest. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=341 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=341 Thu, 13 Jul 2000 12:00:00 CST Recent work with winter rye as a cover crop suggests that you'll need about 18" of height on the rye to achieve 34% residue cover following herbicide suppression with Roundup,shallow disking and planting. Reaching an 18" height took until May 10th. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=340 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=340 Wed, 12 Jul 2000 12:00:00 CST Photos illustrate zone-tillage as a conservation tillage system. Zone-tillage uses coulters to till a strip for planting and/or injecting starter fertilizer in one operation. Taken at French Creek Farms, Manitowoc County, during growing season 2000.Others considering this system may find the images useful. 1) Zone-till wheat in corn silage residue, 7" rows, 2) Zone-till soybeans in corn residue, 15" rows, 3) Zone-till soybeans in wheat residue, 15" rows 4) Zone-till soybeans in corn silage residue with manure, 15" rows, 5)Zone-till corn in wheat residue, 30" rows, 6)Zone-till alfalfa in soybean residue, 7" rows. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=319 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=319 Thu, 15 Jun 2000 12:00:00 CST Soybean in corn residue. Residue=68%. "Blue Jet" coulter caddy ahead of JD1520 press wheel drill; 22" rows. Excellent emergence and stand uniformity. Willow Creek Farms, Manitowoc County. Another excellent system for heavy clay soils. Comments welcome. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=318 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=318 Thu, 15 Jun 2000 12:00:00 CST Zone-till corn in soybean residue. Willow Creek Farms, Manitowoc County. Rawson Zone-Till planter with Kinse row units and 3 wavy coulters. Residue =45%. Excellent stand uniformity. Another example of a system that works well on red clay soils both from a production and a conservation perspective. Additional comments welcome. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=317 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=317 Thu, 15 Jun 2000 12:00:00 CST Zone-till corn in corn residue. Willow Creek Farms, Manitowoc County. Rawson Zone-Till planter with Kinse row units and 3 wavy coulters. Planted last week in April. Residue cover=68%. Excellent emergence and stand uniformity. Good example of a residue management system that works well on red clay soils. Additional comments welcome. http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=308 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=308 Fri, 02 Jun 2000 12:00:00 CST Recent rains of late May and early June 2000 offer graphic reminders of the need for grass waterways and/or residue cover. My sense would be that a waterway would be best in this situation. Additional comments welcome.
