Abstract
Sections of the research farm were tiled in the fall of 1979. The primary reason for the tiling was to provide a good soil environment for large tillage trial plots that had been previously established. This was also used as an opportunity to install a comparison of tile installation with a conventional (at that time) trenching machine and a relatively new system of installing the tile with a trenchless “tile plow” machine. The tile plow inserted plastic tile using a mole approach, which opened the soil and inserted the tile without leaving an open trench, that would later require backfilling. The heaving of the soil by the tile plow did require packing and some soil manipulation to allow cropping. The primary reason for using this type of installation was cost. At the time of this installation, the cost of tiling could be reduced substantially (in some cases by over 50%) by using the plow method rather than the trench.
