Effects of Management Practice on Soybean oil quality.

Effects of Management Practice on Soybean oil quality

Juan Gao, Kurt D. Thelen, and G. Phillip Robertson

Soybean is a major oilseed with high economic value and utility as a livestock feed, food source, fiber feedstock, and recently a renewable fuel source.  In this study, four different crop management systems (tilled conventional with chemical input T1; no-till with chemical input T2;  tilled low input T3; and, tilled non-chemical input T4) were used in a corn-soybean-wheat rotation at Kellogg Biological Station long-term ecological research site from 1993 to 2006.  Total oil yield and the fatty acid profile of soybean oil produced under each management system were measured by accelerated solvent extraction and a gas chromatography-flame ionization detector.  There was no significant difference (p > 0.05) in total oil content among the four crop management systems studied.
