Record ID: ____________________

1. Report identity

Sample ID

Laboratory report number

Laboratory

Report date

Crop, location, bed, field, or intended use

2. Report-wide context

Sample preparation stated?□ Yes □ No □ Unclear

Depth / sampling context attached?□ Yes □ No □ Unknown

Dry-weight or as-received basis stated?□ Dry □ As received □ Other □ Unstated

Laboratory reference ranges included?□ Yes □ No □ Crop-specific

Package name, digestion, extraction, saturation method, or other report-wide notes

3. Result-by-result record

Copy the laboratory wording exactly. Do not convert or combine units until the original value, unit, and method have been preserved.

4. Completeness check

□ Every copied value has its original unit. □ Method or extractant is recorded where the report provides it. □ Total, extractable, available, soluble, saturation, and percentage results remain distinguished. □ “Not reported,” “below detection,” “estimated,” and blank fields have not been treated as zero. □ Laboratory flags and reference ranges remain attached to the correct result. □ Any unit conversion is documented separately without replacing the reported value. □ Comparison reports use compatible methods, units, preparation, and reporting basis—or the difference is marked.

5. Questions and comparison notes

Missing method, unit, basis, detection limit, or laboratory context to confirm

Possible incompatibilities with an earlier or second report
