Methods for Removing Spatial Variability from Field Research Trials
Agronomists and soil scientists concerned with producing food and fiber or improving national food security conduct thousands of field experiments annually to determine which crop varieties, fertilizer rates, or management techniques will optimize crop yield. Because treatment differences in these experiments are often statistically not significant (Trangmar et al., 1987), making recommendations to growers is difficult or impossible.
