Soil Sampling Equipment Recommendation:

Option One:

JMC Backsaver N-2 Handle with JMC Large Diameter Sampling Tube ($285-$295)
Best method for plow-layer sampling. Very portable. Footpedal offers extra leverage in dry soils. Several tubes available.

Option Two:

Works well in tilled soils only. No footstep. Uses same sampling tubes as option one.

Option Three:

JMC T-Handle and Large Diameter Sampling Tube ($260-$630)
Inexpensive method for sampling hard soils. Uses same sampling tubes as option one.
