The Soil Probe is a soil maintenance tool that is used to take samples of your soil and to sample root growth beneath the surface.
Measuring 8" in length with a 1" diameter, the soil tester allows you to take 0.59" x 4 3/4" deep soil sample. The convenient size allows for it to be extremely portable and can even fit in your back pocket.
A benefit of this soil sampler is that it helps determine if the soil requires aeration and helps determine the correct fertilizer to choose for root development.
