Soil Sampler Best Buy
“I do a lot of soil sampling for my work at the University of Minnesota. I use a standard probe for most of it. However, when I can’t push it into the soil, I have to use a mallet to get to the right depth. I can end up bending the handle, and those probes can’t be rewelded.
“There are some probes that are reinforced for hammering, but I’ve been using the bucket and auger device instead. I just set it down, drill down to depth, and the soil collects in the bucket. Then I go on to the next of several spots and collect more samples. The pour spout on the bucket makes it easy to fill the sample bag.
“There are two possible downsides. One is you can’t get a visual image of the soil profile like you can with a probe, as required for some government programs. The other is the sample can be biased if you don’t drill deep enough.
“The first concern is certainly valid. As to the second, we compared the bucket and auger to a probe and felt the amounts of soil gathered seemed to be the same.
“The one definite drawback is you may need to bring lots of batteries for hard-packed soil if you are pulling lots of samples.”
