Soil Parameter Mapping and Ad Hoc Power Analysis to Increase Blocking Efficiency Prior to Establishing a Long-Term Field Experiment

<div>Subplot means for organic matter (b) and weeds (c-d) and four different blocking patterns evaluated for blocking efficiency with power analysis: blocking from west to east (a), blocking to optimize organic matter (b), blocking to optimize weeds, version 1 (c), and blocking to optimize weeds, version 2 (d). TTL weeds = total weeds, OM = organic matter.</div>
