What I Am Learning and Implementing Based on
Data Collected on My FarmDoyle Johannes
ND Discovery Farms Core Farm OperatorUnderwood, ND
History of Involvement
•Started investigating feedlot runoff issues in 2005
•Looked to the future of sustaining the farming operation for the next generation
Why I Got Involved in DF’s
Doyle Johannes, Underwood400-600 custom fed & backgroundingEdge of feedlot monitoring
What I am Learning
Table 1. Total Nitrogen Load and Runoff Flow at the Edge of a Feedlot (G1) and 1/2 (G3) mile down-landscape from the feedlot during the snowmelt period of 2009, 2010 and 2011.
G1 G3
Total Nitrogen Load (lbs) 11793 5441
Total Flow (cu ft/sec) 14 70
Nutrient Loading from Feedlot
What I am Learning
•Biggest loss of nutrients from feedlot area is during snowmelt.
•Over a three year period, summer rainfall events rarely triggered collection at station 3.
My Response
•Need to decrease risk of snowmelt runoff leaving feedlot area
•Installed clean water diversion around feedlot
Diversion
New Feed Bunks
Diversion
Updated Bunk
Unexpected Learning Opportunities
•Several visits from EPA officials
Questions?
