My field season begins...

...with soil sampling at a waste water irrigated hay field. The study site has high gravel content which is farly well sorted due to the action of glacial age Missoula floods. In the picture, the AMS tile probe helps locate high gravel content areas to avoid sampling. The AMS mud bucket auger has wide-set teeth that accommodates the smaller gravels. The 0.25 inch screen helps reduce the sample for shipping. The screen also aids in mixing the sample prior to reduction.
