The Oakfield Apparatus Soil Compaction Tester is specially designed for determining surface compaction or hard pan layers. This one-piece unit has an 8” welded handle and rod that is 1/2" in diameter. There are graduated depth markings at 6", 9", 12", so you know how far down the hard layers go. It comes equipped with a replaceable, screw-on Soil Compaction Tip with sharp arrow design to dig deep.
It's incredibly easy to use, simply push the tester into the ground and make note of how far down the layers go. This convenient, practical tool will help you examine potential soil structure destruction and find problem areas that can inhibit root growth and reduce yields.
As a single unit, it's incredibly durable and there's nothing to take apart, so it's easy to grab and go. Made with the exceptional workmanship and materials, it is finely machined for smooth, easy testing, and long-lasting durability. It is constructed of high-grade nickel chrome plated steel for extra rust, tarnish and corrosion resistance.
