thread261-293009: degree of saturation for organic soils
i have found the degree of saturation of an organic soil sample to be 234%. is it possible for the organic soils? what should be the correct oven drying temperature for organic soils. i have used both 77 and 105 degree celsius. there was not much varation.

RE: organic soil
I'd have no problem recognizing that organic soils can have natural moisture contents of 200 percent (or greater). Just saw a report today and noticed a moisture content value of about 190 percent.
Please recognize that soil that's primarily organic matter has a specific gravity of "soil" grains that's much less than soil. Moisture content is weight of water divided by weight of solids. If the solids don't weigh much (and there's a lot of water), you'll get a high value.
Nothing wrong with rechecking your work, your oven and your proceedure, but you're likely on the right track.

RE: organic soil
Provide comparison of oven dry liquid limit to air dry liquid limit per ASTM D 4318 to determine if soil if organic.
Classify organic soils per D 2487.
Provide an organic content test by ASTM D 2974 as additional back-up.
