Quality, as measured in several ways, is of increasing importance to soybean markets. Since 1972, customers have reported differences in protein and oil contents among soybeans of different origins (Hurburgh, et al., 1990). Geographic differences in composition are primarily caused by weather and environmental factors. In recent years, soybean component variations have been studied extensively (Westgate, et al., 1999). From a customer perspective, monitoring of crop quality on an annual basis is important to estimate outputs and value.
