Our editorial approach

One clear purpose per guide

Our guides focus on measurement, units, package labels, and purchase comparisons. They support the calculator rather than promising a complete growing plan. Published examples are original illustrative calculations, clearly identified as examples.

Sources and scope

We prefer primary references such as national measurement authorities and university extension services. Links appear with each guide. Regional gardening guidance is not presented as a universal rule. A cited institution has not endorsed this website.

Authorship and AI assistance

The current content was prepared with AI assistance for this independent website project. “Raised Bed Soil Planner editorial project” is a project label, not a named horticultural expert. We do not invent professional credentials, field trials, customer stories, photographs, or first-hand gardening experience.

Calculation checks

Examples are checked against the documented formulas and automated calculation tests. Software tests support arithmetic reliability; they do not establish the suitability of a product, growing technique, or real-world order.

Corrections and updates

Guides display publication and review dates. A material correction should update the affected text, example, tests where relevant, and review date. The current public contact channel is pending; see Contact & corrections for the information useful in reproducing an issue.

Commercial relationships

This edition has no ads, affiliate links, sponsored reviews, or supplier partnerships. Any future commercial content must be identifiable, and the privacy notice must describe actual data practices.
