Cob RE: jar test for soilJohn Straube jfstraube at golden.netThu Oct 22 12:03:27 CDT 1998
I certainly dont think the jar test is useless. Many people havent a clue about their soil, and the jar test is very useful to tell someone what the fine content of a soil is. Sure, an expert can take a look at the soil on a property and quickly decide how to mix them and what to add. Us laymen must rely on some simple rules, and simple tests, like the jar test, before we invest the time and effort in the ultimate test -- samples.

Well, I already suspected that the jar test wasn't very precise, but as now both of you (and perhaps others, who's posts I haven't seen so far) say that it is plainly useless, I'll better believe that. Probably it's only merit is that it could be used as a starting point, when you have absolutely no idea about the composition of the soil. The jar test could tell you aproximately how to begin; but that seems to be about all.
