Logan sampling checklist | Living Soil Supplies

1. Identify your sample

Sample ID (optional)Use the same ID on the soil bag, water bottle and worksheet.

Sampling date (optional)

Actual sampling depth (optional)

Record the depth you sampled.
The treatment depth used for amendment amounts is a separate choice.

Requested package

2. Confirm your reporting requests

Measured bulk density.Ask for the units and measurement basis.
Confirm availability, sample requirements and any extra charge with Logan.

Actual organic matter percentage, including results above 20%.Ask for a numeric percentage rather than only a greater-than result.

Mineral results in ppm, with the reporting basis stated.Organic matter and base saturation stay in percent.
Keep M3 and saturated paste results separate.

Use my supplied irrigation water for saturated paste preparation.Select this only when you are supplying water and requesting a paste test.
Confirm the water volume and preparation arrangements with Logan.
This does not order a separate irrigation-water analysis.

The package and reporting requests are choices to confirm with Logan.

Confirm any additional fee before sending your sample.

Read or select the request text

3. Check before shipping

Collect the sample using Logan’s directions for your sample type.Read Logan’s collection instructions.

Provide at least 2 cups of soil per sample.Logan’s worksheet also allows filling its sample bag to the marked fill line.

Label each soil bag with your name and sample ID.Match the ID on the worksheet.
Record the actual sampling depth.

Complete the official submission worksheet and include your extra requests.If sending irrigation water for paste preparation, label it to match the soil sample.
Request that preparation explicitly.

Seal the containers and pack them so they cannot move.Protect the worksheet from wet samples.

Check Logan’s shipping requirements for your location.Contact Logan before shipping soil from outside the continental United States.
Its sampling page also links to guidance for regulated areas within the United States.

4. Match the reports when they arrive

Open the M3 and saturated paste reports separately.Match their sample IDs and dates before combining them in the calculator.

Check results, units, reporting limits and the paste preparation water.Keep each test method and its printed reporting basis.
Enter the confirmed bulk density before calculating amendment amounts.

Build your own version

Copy a starting prompt into ChatGPT or another coding assistant, then adapt it to your needs.

These prompts describe the framework and workflows. They are not the source code, a bundled dataset or a promise of an identical result.

Check the reuse terms for any third party text, images, recordings or datasets before including them in your version.

Starting prompt for Living Soil Supplies

Build a mobile friendly soil and water test workspace inspired by Living Soil Supplies.
Start with a homepage that links to a calculator, pots and beds planner, water readouts, test history, report viewer, learning resources and offline access.
Keep each task clear and put long explanations in expandable sections.
Use short sentences with space between them.

Let people open separate Logan Labs Mehlich 3 and saturated paste reports, choose the matching samples and review imported values before using them.
Support local PDF and spreadsheet parsing when practical, plus manual entry.
Keep original units, chemical forms, sample identifiers and test methods visible.
Missing, uncertain or unsupported values must remain unknown rather than become zero.
Use fictional examples until the user confirms their own values.

Calculate soil mass from confirmed dimensions, depth and bulk density.
Show nutrient gaps, attributed ratio references, application limits and product amounts with the arithmetic explained.
Allow multiple products for one element and keep shares at 100 percent.
Count all known accompanying nutrients without adding the same contribution twice.
Keep nitrate results separate from total nitrogen additions.
Keep Soil Symbiotics out of the mineral amendment selectors and describe any verified directions separately.
For water reports, show measured concentrations, ratios and amounts already present in the selected water volume.
Do not treat the water readout as a balancing prescription.

Process personal reports locally, provide backup and restore files, and test calculations with synthetic fixtures.
Package the interface and permitted data for offline use.
Explain which external resources still need internet access.
Cite sources and dates for technical targets and product analyses.
Do not copy private reports, paid course material or restricted datasets.
Ask for reuse terms before redistributing third party content.

Deliver a working first version, instructions and a list of unverified assumptions.
To adapt this framework to another topic, replace the data and calculation rules while preserving review, provenance, local storage and export.
