How

1. Complete the Solution Sample Submission Form for Researchers and include it with the solution sample (s).  Samples will not be accepted without this form.
2. Complete the Solution Sample ID Continuation Page and include it with the plant sample (s).
3. Include a printed copy of the signed (by the Agronomic Division) NCDA Cooperative Research Agreement with each batch of samples.
4. Samples will not be accepted without these three documents included in each batch.
5. If you have a large batch of samples, please notify the lab supervisor of an estimated delivery time.

Minimum Sample Volume:

No matter how precise and accurate an analytical method is, meaningful results are only as good as the sample itself.  The most significant cause of poor statistical results in solution analysis is due to imprecise sample collection and preparation rather than analytical measurement. To obtain a representative sample, NCDA&CS strongly recommends a sample volume of 8-16 oz (~500 mL).  Where this is not possible, please note the minimum sample volume required to perform each analysis (Table 1). Researchers that fail to submit the minimum of 75 mL will not receive the full standard analysis--pH, EC and alkalinity will be automatically omitted.
