PURPOSE:
• Reduce Erosion From Farm Fields
• Compare Conventional vs. One-Till Systems
• Reduce Sediment in Oneida Lake
• Reduce Phosphorous in Oneida Lake
.........................................................................

Lessons Learned From 2007 Program:
• A thick sod should be killed with herbicide at least a month before tillage
• One farmer planted successfully into an annual rye cover crop that had been killed a short time before tillage
• The zone builder implement will pull up a lot of rocks just as a chisel plow would
• Correct use of herbicides is critical though no more herbicide was required than with conventional tillage
• The zone builder was able to noticeably reduce the effects of compaction
• Yields were not reduced with the zone builder when used correctly
• The Unverferth Company states that 40 HP is needed per shank but we were successful using a 230 HP Case-I.H. Magnum tractor

ONEIDA LAKE WATERSHED ZONE BUILDER DEMONSTRATION PROGRAM
Available in the Oneida Lake Watershed in Madison, Oneida, & Onondaga Counties

How it Works:
• Implement is available for 50 to 100 acres per farm at no charge • Provided on a first come-first serve basis
• Scheduling consideration given to distance needed to move implement
• Farmer supplies tractor, 240 HP required, Case-I.H. Magnum has been sufficient
• Farmer picks up implement from previous farm, implement has a pintle hitch, and the implement is 19 feet wide going down the road • Farmer signs agreement to not abuse implement and maintain implement as needed
• Madison County SWCD personnel inspect implement before and after use
• SWCD personnel will limit use of implement from very rocky soil in order to extend life of implement and maintain its availability
• Agronomic advice provided by Jeff Miller, Cornell Cooperative Extension of Oneida County
