2021 OHIO CORN WATER MANAGEMENT STUDY TILE SPACING
The purpose of this study is to compare different subsurface tile widths and their effects on yield and return on investment (ROI).
Every year is different, and your farm, your soils, and their hydrologic characteristics will determine the proper tile size and spacing. One thing is clear from this multi-year study, however; tile pays.
