Variations in management inputs and climatic conditions between fields and from year to year are major complicating factors in attempts to quantify soil productivity. A study of soil productivity for spring wheat ( Triticum aestivum ) in northcentral Montana is used to illustrate the advantage of the paired sampling technique as compared to a non‐paired design for evaluating yields on contrasting soils. The two soils in the study were both Aridic Argiborolls which occur as a complex in the same fields. Relative efficiency of the paired design compared to nonpaired sampling ranged from 0.9 to 6.5 for the 11 crop and soil variables measured (mean relative efficiency was 2.0).
