Soil Sampling

Soil is not uniform in the field; it varies from one place to another because of natural causes and human activities. To truly represent the fertility of your field, a minimum of 15 sub-samples are needed to make a composite sample for laboratory analysis. Appropriate sampling depth is 0 to 6".
