Evidence for Lunar-Sidereal Rhythms in Crop Yield: A Review Nicholas Kollerstrom and Gerhard Staudenmaier Biological Agriculture and Horticulture, 2001, Vol. 19. p. 247-259.
In this paper, a re-analysis of research data found significant lunar influence according to the Thun calendar. It especially addresses the research of H. Spiess published in 1990, which refuted the "Thun effect." This paper contains the important literature citations on moon and plant growth; rhythmic nature of animals and plants; zodiac rhythms in plant growth; testing the lunar calendar; biodynamic calendars and crop management; cosmic influences on plant growth; etc. It is an essential paper -- in a series -- for the biodynamic library, in reference to biodynamic calendars, cosmic influences on plant growth, and "planting by the moon."
