For every $1 spent on drainage technology, producers get $3 to $4 back in corn and soybean profits, according to long-term Ohio State University research.
Twenty-five years of field studies (from 1984 to 2009) at the Ohio Agricultural Research and Development Center (OARDC) Northwest Agricultural Research Station in Hoyvtille showed that subsurface drainage significantly improved corn and soybean yields on poorly drained soils. Add crop rotation and some sort of conservation tillage practice and production just keeps getting better.
"Overall, a farming system that includes subsurface drainage, crop rotation, and no-till, or other conservation tillage system, provides the best long-term economic and environmental benefits for the farmer," said Randall Reeder, an Ohio State University Extension agricultural engineer.
