In 1979, a portion of the research farm was pattern tiled. This was used as an opportunity to compare tile installation methods: a conventional trenching machine (used widely prior to late 1970s) and a trenchless “tile plow” machine. The tile plow inserted plastic tile using a mole approach, which is the current primary tiling method. This research showed plow and trenching tiling methods were not significantly different and both provided adequate drainage. It also showed that water table measurements were influenced more by timing of water needs of the crop being grown and intensity of the rainfall event than tiling method. This report focuses on continued water table monitoring from 2012 to 2013
