Application of GPS and Near-Surface Geophysical Methods to Evaluate Differences Between Agricultural Test Plots

A field research facility with two pairs of replicated agricultural test plots (four total) was<br>established at a location in northwest Ohio during 2005 for the purpose of studying water table<br>management strategies. Initial efforts at this field research facility were devoted to evaluating<br>differences between replicated test plots in regard to topography, subsurface drainage system<br>characteristics, and soil properties.
