Use a zigzag random approach when taking samples and subdivide non-uniform fields into smaller, more uniform areas.
Taking soil samples at random locations throughout your field is important to get a good representative picture of your soil conditions.
One way to ensure this is to use a zigzag pattern across
the entire area.
Don't take all of your samples:
- from one side of the field
- only from the corners of the field
- from the same spot on each side of the field
Random sampling ensures "non-bias" in your soil sample. This results in a sample that is representative of your entire field.
