The major equipment used in soil sampling is the Auger but incase it is absent, the following tools can be used.
- Transverse method
- Zig Zag method
- Spot method
In this method, diagonals are drawn across the field/area to be sampled and sites are selected along those diagonals
Zig Zag Method
Here, sites are chosen at random in the entire field as shown below without any formula
In this method, one location is chosen randomly. This is suitable for small pieces of land of about 0.25 acre.
