Practical impact of lunar phases.
Agriculture and gardening.
The lunar calendar has been used for centuries by farmers to plan activities such as planting and harvesting. The phases of the moon influence soil moisture levels and plant growth. For example:
- Waxing Quarter : Ideal for planting crops that grow above the ground, such as corn and wheat.
- Full Moon : Optimal for watering and fertilizing, since gravitational attraction increases the absorption of nutrients by the roots.
- Last Quarter : Appropriate time to prune plants and remove weeds.
Tides and maritime activities.
Lunar phases also have a direct impact on tides. During the New Moon and Full Moon, tides are highest due to the alignment of the Sun, Moon and Earth, a phenomenon known as “spring tides.” This is especially relevant for fishermen, surfers and coastal communities who plan their activities around the lunar cycle.
