10672. Huyck, L.M.. 1989. Effects of slope position, season, and long-term management on aggregate stability in an organically and conventionally farmed Naff silt loam.. M.S. thesis, Dept. Crop & Soil Sciences, Washington State Univ., Pullman, WA 99164-6420.
Aggregate stability was compared on adjacent fields under contrasting long-term management. Samples were taken in October, March, and June and tested for aggregate stability for the 0.5-1.0 mm size fraction. Stability decreased significantly going upslope, and also after freezing and thawing. Each farm had its own pattern of stability. Soil carbon was highly correlated with stability on the organic farm, but not on the conventional farm. While stability was significantly higher on the organic farm under certain instances, this was not always the case and no conclusion can be drawn about which system had better aggregate stability.
