Farming knowledge, put in season order.

Yes, completely free to use. The site is funded by display advertising and, where clearly labelled, affiliate links to seed and input suppliers. Neither ever appears inside tools, charts or the farm model, and commercial relationships never influence what the guidance says.

Guides are written in-house against a fixed page template, with every factual claim tied to a cited source. Each page is reviewed by a qualified agronomist before publishing and carries a last-reviewed date. AI tools may speed drafting but never replace source citation and expert review.

Crop requirements (temperature, pH, spacing) draw primarily on FAO's ECOCROP database, now accessible via the GAEZ platform. Weather data uses Open-Meteo's API. Soil estimates use ISRIC SoilGrids modelled data, always labelled as estimates. Every chart and tool states its source and the region it applies to.

A range that is right in one region can be wrong in another. A soil pH of 6.5 suits wheat in most temperate climates but is too high for blueberries anywhere. Fieldbook always says what kind of number you are looking at — typical range (general reference), calculated (from your inputs), or local data (weather or soil for your location). The right specific advice comes from a soil test, a seed label and a local agronomist.

No. Pesticide registration differs by country, and the wrong product or rate can damage crops, harm the environment, or break the law. V1 pages describe pest and disease identification, scouting principles and economic thresholds, then point to the product label and the local regulatory authority. Always follow your country's registered product list.

Without a location set, Fieldbook shows stages and conditions only — never calendar dates as fact. When you set a location, it uses climate data (frost dates, soil-warming thresholds, growing degree days) to derive approximate planting windows. These are estimates, not prescriptions. Southern-hemisphere users see correctly adjusted dates; no content hard-codes northern months as universal.

No. It is a teaching illustration built entirely in CSS — a flat grid tilted with a CSS transform, with box-shadows for visual depth. Plot sizes are not to scale. It is there to make crop and stage navigation tactile, not to represent any real field layout.

Embeddable calculators with attribution are planned for V3. In the meantime, every tool result and checklist can be printed or exported as PDF with full source attribution.

No. Fieldbook is an independent product. It uses openly licensed data from FAO, Open-Meteo and ISRIC and follows their attribution requirements, but it is not affiliated with, endorsed by, or funded by any government body or intergovernmental organisation.
