Abstract

Abstract

In a study initiated in 1977, eight laboratories representing experiment stations of the North Central Region plus the USDA-SCS National Soil Survey Laboratory determined some of the most common soil properties used for classification and other purposes. Ten horizon samples were selected from soils throughout the region with the intent to include a variety of differences in physical and chemical properties. Estimates of the standard deviation from the mean of physical and chemical properties were derived. There were no significant differences among laboratories in the determination of Ca, Na, base saturation, available P, and CaCO3 equivalent but there were significant differences in determination of Mg, K, H, cation exchange capacity, organic carbon, and pH in water and in CaCl2. These differences suggest that uniformity in procedures among laboratories must be emphasized.
