a Average RVRT*, represented by the fixed λ in the first column and the management zone in
the column, is determined by averaging the RVRT*s for fields with all combinations of the
other twoλ s. For instance, the $9.43/acre return in the column headed Management Zone 1 is
the average return when the field is 90% management zone 1 and either 10% management zone
2 ($16.38/acre) or 10% management zone 3 ($2.37/acre).
