Fertilabel / How we verify

How we verify every rule we publish

There is no federal fertilizer registry in the United States, so there is no single authoritative list to copy. Everything on this site was read from a state statute or an agency page, one at a time. This is exactly how, including the parts we have not managed to confirm.

The method, in four steps

1. Primary sources only

Every figure comes from the state's own statute or its agency's page. Not from a consultant's blog, not from another compliance vendor, not from an AI summary. Where the statute and the agency disagree — Wisconsin is the clearest case, where the statute still says 23 cents a ton and the agency charges 62 plus a surcharge — we publish what the agency charges and say why.

2. Every rule carries its date

Each state page prints the date we last read its sources. A rule verified in August is not the same as one verified yesterday, and you deserve to know which you are relying on.

3. What we cannot confirm, we mark

Where a source is unreadable, blocked or silent, the field says “Not verified” in red instead of carrying a plausible number. Today that applies to parts of 18 of the 50 states we cover. A gap you can see is safer than a number you cannot check: if we guessed and you filed on it, the penalty would be yours.

4. When two official sources disagree, we print both

We do not pick the one that reads better. The state page shows the disagreement in a box and says we do not know yet. Open questions right now:

OPEN QUESTIONSAS OF SEP 5, 2026

When we get it wrong

We publish the correction rather than quietly editing the page. In September we found we had collapsed Florida's two separate late penalties into one line — they punish different failures and can both apply — and we wrote it up in the Filing Desk with the date it changed.

Who writes this

The rules desk that maintains the library. We publish under the company name rather than personal bylines, because what should carry weight here is the source under each figure, not a photograph. Every claim on this site links to the statute or agency page it came from — check any of them, that is the point.

What this is not

It is not legal advice, and we are not a law firm. We prepare paperwork and keep calendars; we do not certify products, we do not file on your behalf and we never hold your state portal credentials. You remain the registrant of record, and the obligation to file correctly is yours. Always confirm with the agency before you file.

See it for yourself

Open any state page and follow the sources at the bottom. If a figure has no source, it should not be there — tell us.
