Abstract
In 1979, a portion of the research farm was pattern tiled. Two drainage installation methods were compared: a conventional trenching machine (used widely prior to the late 1970s) and a trenchless “tile plow” machine. This research showed both tiling methods were not significantly different and both provided adequate drainage. It also showed water table measurements were influenced more by timing of water needs of the crop being grown, intensity of the rainfall event, and distance from tile drainage lines, than tiling method. This report focuses on continued water table monitoring from 2017 to 2020.
