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

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
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
A few companies evenspecialize in precision cultivation
“Flexibility to satisfy all your hoe requirements”
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.
Garford dealer – Canadian company that sells into the Upper Midwest
start up company – no commercial products yet http://bluerivert.com/
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?????
Precise banding will probably be needed for ROI
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
NT bean yields ranged from ~ 30 to ~ 60 bu/a 60 b/a in wet hole 30-40 b/a in well drained areas
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.
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
CCs affect many agronomic factors simultaneously Control erosion Feed livestock Cover Crops Adapted from Magdoff and Weil (2004)
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)
Greater precision in farming practices increases the likelihood of intended outcomes More positive and fewer negative effects
This is what we were hoping for in the field where we ended up planting our precision radish experiment in fall 2012!
