19. Most of the power required for tillage isAgriCanada associated with undoing wheel traffic Without restricted traffic, most field surfaces receive traffic each year
20. RTK-guidance/auto-steer makes controlled traffic much easierwww.mitchellfarm.com

23. 8 ways that your equipment may get smarter 1. Enhanced guidance and connectivity, implements guiding tractors and not the other way around 2. Autonomous machines? Eventually 3. Smarter telemetrics 4. Better sensors 5. Improve diesel fuel economy 6. Emission regs drive change 7. Small is big 8. Going electric
24. http://www.hoosieragtoday.com/index.php/2012/03/04/the-end-of-the-chemical-era/ Big equipment companies are starting to design new cultivation tools for controlling herbicide resistant weeds
25. A few companies evenspecialize in precision cultivation
26. “Flexibility to satisfy all your hoe requirements”
27. The Tillet Weeder uses computer technology and a spinning blade to remove weeds. Note the disc-shaped cultivation blade with a notched cut-out to allow the blade to spin around transplanted cabbage.
28. Garford dealer – Canadian company that sells into the Upper Midwest
29. start up company – no commercial products yet http://bluerivert.com/
30. BRTs vision forthe future
31. The founding team is two brothers, one a large-scale dairyman from NY State and the other an engineer and environmental scientist based in Minnesota. We are working closely with a robotics team that has deep experience engineering high-quality products for start up company agriculture and other markets.no commercial products yet Robotic weeding 1 row at a time?????
32. Precise banding will probably be needed for ROI
33. What is PRECISION COVER CROPPING??? 1) Planting of cover crops with a precision planter2) strategic placement of cover crop rows in relationto other cover cover rows and/or the following cash crop rows (often using GPS guidance) 3) Strategic placement of cover crops in specific fields or parts of fields 4) Selection and management of cover crops to achieve specific objectives
38. Attempt #3 Radish planted on 30” rows usingsmall milo plates in mid-August 2010
39. Corn following cover crop experiment (2011) Relative Cover crop system corn yield Volunteer oats 79% Radishes planted on 30” 99% Radishes drilled on 7.5” 91%Corn planted directly over radish rows
40. May 2012
41. Radish planted on 30” rows with RTK guidance on August 29th right before Hurricane Isaac rolled in
42. 4 days later
43. 7 days after planting
44. 10 days after planting
45. ~ 1 month later
46. Why are the inter-rows so clean?
47. We had just cultivated the radishes! +20 bu/a corn in plots w/ fall cultivation vs. no cultivation of radish in 2012
48. ~ 2 weeks later
49. December 2012 We are planning to plant corndirectly over the radish rows in 2013
50. Precision radishes w/o peas Precision planted radishes w/ peas from 5 ft of rowRadishes with peas were ~20% larger
51. Crimson Chick clover peas We are using small plots to identify cover crops that play well togetherGreen Favalentils beans
52. Sunflower OatsRapeseed Phacelia
53. Do you wantboth species to winter kill?
54. Planted with a drill in late September 2012 Precision planting may allow you to plant your cover crops later Radish Radish Radish Cereal Cereal Rye Rye
55. Littleradishescan have long roots!
56. Would you be comfortable planting a field in this condition?
57. Planting right on top of ridged radishes
58. Last fall we set up a 6 row bar with Yetter MavericksWe plan to freshen rows before planting as needed
59. Why is there rapeseed on the edge of this bean field? We ran rapeseed (2 lbs/a) through insecticide boxes while planting these soybeans
60. 40 lbs of cereal rye planted directly over soybean rows in 2011 The cereal rye and rapeseed both died when the crop canopied. No significant effect on yield, some in-row weed suppression in 2011
61. Insecticide boxes do a good job of metering small seeds
62. A little extra N can make a big difference +20 lbs N/a
63. Triple S mixSunflowers, Soybeans & Sunnhemp
64. What do youthink is in this CC cocktail?
65. You won’t reallyknow what is in a mix unless you design it.
66. Aerial seeded annual ryegrass in April 2012
67. 10’ Howard Rotavator tilling ~ 3” deep with C blades
68. Annual ryegrass after chisel plowingChiseling before rotavating worked best!
69. Planting into poorly digested red clover residues 25-50% stand loss Near perfect stands in all other corn plots on the farm this past spring
70. Organic No-till? Much less weed seed germinationRodale roller …but few options for weed termination Cultimulcher
71. Early July 2009
72. August 2009
73. Early November 2009Plot yields ranged from 51.6 to 58.6 bu/ac No significant differences between systems
74. November 2010 Significant foxtail pressure but almost no broadleaf weedsPlot yields ranged from 42-52 bu/ac
75. November 2011The NT bean plots yielded~10 bu more than the best tillage system plots
76. April 2012
77. May 10 2012
78. Double drilled with 4” offset
79. Mid June
80. All of July :-<
81. NT bean yields ranged from ~ 30 to ~ 60 bu/a 60 b/a in wet hole 30-40 b/a in well drained areas
82. Our cleanest and best yielding beans in 2012 were conventional-till but we have not been able to achievethis level of weed control every year.
83. Where are the soybeans?? Traditional organic weed management often comes up short during wet yearsA strong stand of cereal rye was incorporated ~ 2 weeks before these soybeans were planted
84. CCs affect many agronomic factors simultaneously Control erosion Feed livestock Cover Crops Adapted from Magdoff and Weil (2004)
85. Not all effects are positive Host pests Tie up N ? ? Become a weed Interfere w/ equipment performanceSuppress crop growth Cover Crops Dry out soil Prevent excessively soil drying Add cost Increase management Adapted from Magdoff and Weil (2004)
86. Greater precision in farming practices increases the likelihood of intended outcomes More positive and fewer negative effects
87. This is what we were hoping for in the field where we ended up planting our precision radish experiment in fall 2012!
