Frequently Asked Questions

Is the archived Issue 020 PDF complete?

Yes. The eight landscape scans contain printed pages 1–16 in booklet order. No missing or duplicate spread was found.
What evidence does the occultation update provide?

It adds dates, revises an earlier rarity assumption, and offers an agricultural cold event as an anecdotal coincidence. It does not systematically compare weather records or establish that occultations affect farms.
What is the strongest comparison in “Observations & Experiments”?

A student basil test compared BD 507, nettle tea, kelp tea, and plain water under artificial cold with independent damage ratings. BD 507 and water performed about equally; the small test was considered provisional and slated for repetition.
What does the hydraulic stirring-machine article demonstrate?

It documents a working farm-built system for larger volumes, including drive, reversal, vessel, and workflow choices. It does not show through comparative crop or soil data that the machine outperforms hand stirring.
