About ¾ to 1 cup of soil is required. Ziplock Sandwich bag is perfect. The sample should be taken from about 5 different areas front, back, and side of your yard choosing the worst areas. For most lawns the growing topsoil, the main plant nutrients and the feeding roots are in the top three inches of soil. The sample should be taken from 3-4 inches depth. Mix together and take sample from this for the soil testing.
Avoid Sample Interference: Sample should be taken prior to fertilizing or 4 weeks after. Do not include compost or mulch in the sample.
