Small-Plot versus Field-Scale Experiments for Fertility Research

Precision agriculture technologies have reduced the cost of data collection, but

most on-farm comparisons continue to be large block, split field or paired field

comparisons with little or no replication. For logistical reasons, relatively few are

split planter, strip trials or other on-farm designs derived from classical small plot

experiments. The general objective of this study was to determine if spatial

analysis could help farmers make better use of the limited replication data they

are currently collecting with yield monitors.
