What it means	The certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.	Australia's largest organic certifier, accredited under the Australian National Standard for Organic and Bio-Dynamic Produce. The bud-and-leaf logo is the most-seen organic mark in Australian supermarkets.	A German farmers' association whose private organic standard is stricter than the EU baseline. Covers food, aquaculture, textiles, and cosmetics. Recognised globally.	The UK's largest organic certifier. Standards are stricter than the UK government's baseline (which still mirrors EU 2018/848 post-Brexit). Recognised by the EU and USA under equivalence.

Guarantees	All organic standards PLUS biodynamic preparations and whole-farm planning. Whole-farm certification (not single fields/products). Annual on-site inspection by Demeter-accredited inspectors. Animal welfare standards stricter than baseline organic.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare and biodynamic-compatible production options.	Stricter than EU 2018/848 (lower nitrogen inputs, full-farm conversion, social standards). Annual on-site inspection. Fair-pricing requirements for member farmers.	Stricter-than-baseline organic standards across food, textiles, cosmetics, and farming. Annual on-site inspection. Animal welfare standards (outdoor access, lower stocking density).
Does NOT	Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.	Membership-based — only farms that join the Naturland association can use the mark.	Logo is trademarked — not a free-licence mark.
