# = weighed wet a day later (but kept cold to reduce water loss)

Wiki Markup\* = weight after a bit of time in the oven \ :( \ [forgot to write down first reading\], water content will be a bit low, but dry density will be okay

Here is a quick comparison of the weights of various objects with the borrowed scale and ours.  The borrowed scale read within 1g, so I wouldn't change any of the above readings.

...

I mistakenly started weighing the soil in ounces, so we continued this in order to make a consistent table.

Ring diameter = 2 3/32" = 2.094" = 5.319 cm; volume = 66.66 cm^3;  1 oz = 28.35 gm

Qsoil = 1 - dry/wet; h2o volume fraction = (wet-dry)/(1 gm per cm^3)/sample-volume
