Lunar Effect on Thoroughbred Mare Fertility - Nicholas Kollerstrom

Nicholas Kollerstrom
An Analysis of 14 Years of Data, 1986-1999  
Published in "Biological Rhythm Research" 2004 Vol.35 Nos. 4/5

14 years of data from the breeding records of a major UK  stud farm were used in order to determine whether a relationship exists between successful conception rates and the phases of the moon. The coverings of mares by stallions which had been recorded on a daily basis throughout the breeding season were compared with the number of registered conceptions that resulted.   

Results showed that mares came in season more frequently in the days following full moon. This period also resulted in more conceptions. The influence was strongest during 'high node moons', the period in the moon's nodal cycle in which the full moon lies above the ecliptic.

Evidence for Lunar-Sidereal Rhythms in Crop Yield

Nicholas Kollerstrom and Gerhard Staudenmaier
A Review. Published in "Biological Agriculture and Horticulture" 2001, Vol. 19

This paper reviews the data evidence collected over the last 40 years by Abele, Kollerstrom, Lücke, Graf, Thun and Spiess into the effects of the sidereal rhythm of the moon on plant growth.
Of particular interest was the apparent discrepancy in the findings of Spiess whose results appeared to refute these effects. The data was carefully re-analysed and compared. Following careful re-analysis, the evidence demonstrated that the results even of Spiess' work confirmed the earlier findings that the sidereal rhythm does indeed effect germination and growth in the way described by Thun and the Biodynamic Sowing and Planting Calendar.
