Careful soil sampling is essential for an accurate fertilizer recommendation. A sample must reflect the overall or average fertility of a field so analyses, interpretations and recommendations accurately represent the nutrient or mineral status of the soil. An accurate evaluation of soil nutrient levels will result in more efficient fertilizer use, which can increase yields, reduce costs and potentially reduce environmental pollution.

Consider each of the following before obtaining a soil sample:
1.  field area (acreage) per sample,
2. sampling procedure,
3. sampling depth,
4. when to sample,
5. sampling tools,
6. sample handling,
7. information form, and
8. handling and mailing.
