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.
  • New Zealand has no single legally-mandated 'organic' definition — voluntary certification is the norm.
  • Membership-based — only farms that join the Naturland association can use the mark.
