Variation of the lunar phase velocity.
.1 The variation of viability in seeds depends in part on the variation of phase velocity of the Moon.
.2 In general, this speed variation depends, in turn, on the changes of the declination of the moon, relative to the Earth's equator, either toward the north, or toward the south.
.3 This declination may go from zero either to just 18°, or up to even 28°40, depending on the year, over a cycle of 18.6 years.
.4 For instance, during the year 2006, the extremes were the most elevated; while, during the year 2015, the extremes will be the most moderated.
If the variation of declination is extreme.
An example of a cycle where the variation of the moon phase velocity was rather elevated.
.5 If the values of the moon declination change steeply, (1) also the moon phase velocity tend to change at a rapid rate, while (2) the alternance of the periods where the seeds loose degrees viability, and the periods where they restore it, is regular and short.
.6 Consequently: (1) under conditions of normal temperature, the seeds tend not to have large reductions in their viability, (2) nor to have a striking recovery of it, because the variation of the moon phase velocity is most of the time elevated.
.7 Thus, the viability values tend to remain on the average. Choosing the days of sowing, following the global cycle - over large numbers - may have a gain of about 10 to 15% only, compared to the earnings obtained in case we do not take into account the global cycle.
If the variation of the declination is moderate.
See various examples of the cycle when the variation of the lunar phase velocity is moderate (years 2013-2016).
.8 If the variation of the moon declination is reduced, the cycles may develop in a number of manners; the alternation between the periods in which the seeds lose viability, with those in which they recover, may be lengthy; that could mean more risks in case you do not know the viability trend.
.9 There could be a sequence of periods a-b and c-d, even of two months long, during which the seeds almost do not have the chance of restoring some degree of viability, followed, as a compensation, by some days where the variation of moon phase velocity keeps under deltins +0.1, the best possible chance to get the best plants possible, of course if the season is the right one.
Risks and benefits.
.10 Therefore, during the years when the change of the moon declination is reduced, not to take into account the cycle before planting is a risk: that of sowing when the seeds are almost devoid of orderly EFAs, i.e. when their viability is at a very low level.
.11 The global cycle may provide the chance to avoid such risks. Moreover, it gives the key to sow just shortly before the beginning of a series of days during which the moon phase velocity keeps increasing very slowly, and have the best possible plants. One has just to choose.
