After three years of evaluating sub-surface drainage in research plots, University of Minnesota Extension Nutrient and Water Management Specialist Lindsay Pease is starting to notice yield differences in the crops. “In a really wet year, we started to see better yields in our drained section compared to the undrained section,” Pease told RRFN. “Unfortunately, in last year’s drought, we saw slightly lower yields in the drained section due to the lack of rain.” This summer, there are more rains and the lift stations are pumping. “We are looking forward to seeing how yields do this year.”
