YBMZ technique compared with the SCMZ technique
could be attributed to lack of weights assigned to the
various data layers (i.e., bare-soil imagery, soil organic
matter, cation exchange capacity, soil texture, and the
previous season’s yield map). We hypothesize thatassigning appropriate weights to the data layers during
the management zone delineation process could increase
the accuracy with which the YBMZ technique
characterizes spatially variable productivity potential.
More research is needed to develop appropriate weights
for the data layers.
