complex interactions of meteorological, biological, anthropogenic, topographic, and edaphic fac-
tors. Furthermore, SSM requires more than just a myopic look at crop productivity. It must balance
sustainability, profitability, crop productivity and quality, optimization of inputs, and minimization
of environmental impacts. Nevertheless, the presented approach is a step forward because it pro-
vides spatial information for use in site-specific soil and crop management.
