3. Aligning with Cosmic Rhythms:
- Biodynamics recognizes the profound influence of celestial rhythms on plant growth.
- Planting, cultivating, and harvesting in harmony with lunar cycles, planetary alignments, and seasonal transitions optimizes plant vitality and yields.
4. Embracing Biodiversity:
- Biodynamic gardens embrace diversity, fostering a tapestry of plant species, insect life, and beneficial organisms.
- This biodiversity fosters resilience, thwarts pests, and creates a harmonious ecosystem where each element contributes to the garden's overall health.
Essential Practices for Biodynamic Gardening Success
1. Composting: The Heart of Soil Fertility
- Biodynamic composting is a meticulous art, transforming organic matter into a nutrient-rich elixir for the soil.
- Specific preparations, such as BD500 and BD502, enhance compost vitality, accelerating decomposition and enriching the soil's microbial life.
2. Planting by the Moon and Stars:
- Biodynamic planting calendars guide gardeners to align sowing and harvesting with auspicious cosmic rhythms.
- This practice is believed to optimize plant growth, nutrient uptake, and flavor development.
3. Fostering Biodiversity:
- Intercropping, companion planting, and cultivating a diversity of species create a vibrant ecosystem that benefits all inhabitants.
- Beneficial insects thrive, pests are kept in check, and the garden becomes a resilient, self-sustaining microcosm.
4. Honoring Animals and Their Role:
- Biodynamic farms often integrate livestock, recognizing their crucial role in nutrient cycling, soil fertility, and overall farm health.
- Animals contribute manure for compost, grazing for weed control, and their unique energy to the farm's ecosystem.

Delving Deeper into the Cosmos: Advanced Biodynamic Techniques
We've established the core principles and practices of biodynamic gardening, but the journey doesn't end there. For those seeking to truly connect with the cosmic rhythms and unlock the full potential of their gardens, several advanced techniques await exploration.
Honing Your Sensitivity to Cosmic Forces
1. Observing the Subtle: Planetary Influences
Each planet in our solar system exerts a unique influence on plant growth. For example:
- Mars: Associated with vitality and action, Mars days are ideal for seeding fast-growing plants like lettuce and radishes.
- Venus: Ruling over love and beauty, Venus days favor planting flowering ornamentals and nurturing delicate fruits.
- Saturn: Known for structure and boundaries, Saturn days are well-suited for tasks like transplanting seedlings and pruning woody plants.
By keeping a keen eye on planetary movements and aligning your gardening activities accordingly, you can tap into these subtle cosmic forces and potentially enhance your yields and harvest quality.
2. Harnessing the Moon's Cycles: The Biodynamic Sowing Calendar
The moon's waxing and waning phases have long been recognized as potent influences on plant growth. Biodynamic sowing calendars, meticulously crafted to correspond with these lunar cycles, offer detailed guidance for optimal planting times.
- Root Days: During the waning moon, focus on planting root vegetables like carrots, potatoes, and beets. The downward pull of the moon's gravity is believed to encourage vigorous root development.
- Leaf Days: Under the waxing moon, prioritize leafy greens like lettuce, spinach, and kale. The moon's upward pull is thought to stimulate lush foliage growth.
- Flower Days: The days surrounding the full moon are auspicious for sowing flowering plants, fruit trees, and herbs. The moon's heightened energy is believed to promote vibrant blooms and bountiful harvests.
3. Rhythms of the Zodiac: A Deeper Dive
For the truly dedicated biodynamic gardener, delving into the specific influences of the zodiacal constellations can add another layer of complexity and potential benefit. Each constellation is associated with different plant parts and qualities, offering further guidance for aligning your gardening activities with cosmic rhythms.
For instance, planting tomatoes under the sign of Leo (associated with fire and fruit) or sowing leafy greens under Libra (linked to air and balance) might be seen as particularly auspicious choices. However, mastering this level of astrological integration requires dedication and ongoing study.
Tools and Preparations for the Advanced Biodynamic Gardener
1. The Seven Preparations: Catalysts for Life
Biodynamic preparations are potent natural concoctions crafted from specific plant and animal materials. These preparations, numbered BD500 through BD507, each address different aspects of soil health and plant vitality.
- BD500 (Horn manure): Enhances soil fertility and humus formation.
- BD501 (Horn silica): Strengthens plant stems and resistance to disease.
- BD502 (Cow manure): Stimulates composting and microbial activity.
- BD503 (Chamomile): Promotes flower formation and fruit quality.
- BD504 (Nettle): Enhances leaf growth and chlorophyll production.
- BD505 (Oak bark): Strengthens root systems and resistance to pests.
- BD506 (Dandelion): Balances soil moisture and nutrient uptake.
Mastering the application and timing of these preparations takes time and experience, but their potential to invigorate your garden and elevate your biodynamic practice is significant.
2. The Dowsing Rod: Intuition Meets Practicality
The dowsing rod, a simple Y-shaped tool, can be used to intuitively locate underground water sources, ley lines (energetic lines in the Earth), and even compost piles with optimal activity. While its scientific validity is debated, many biodynamic gardeners swear by the dowsing rod as a valuable tool for connecting with the subtle energies of the land.
Conclusion: A Lifelong Journey with Biodynamic Gardening
Biodynamic gardening is not merely a set of techniques; it's a lifelong journey of observation, experimentation, and deepening connection with the natural world. As you delve deeper into its principles and practices, you'll witness firsthand the vibrant life force coursing through your garden, responding to your care and resonating with the rhythms of the cosmos.

Уважаемые коллеги!
На заседании Ученого совета в пятницу 22 декабря в 11:30 будет заслушан
доклад:
_П.Д. Григорьев_, Т.И. Могилюк
*Развитие теории магнитосопротивления в слоистых квазидвумерных металлах*
Развита теория поперечного магнитосопротивления в слоистых
квазидвумерных металлах. По формуле Кубо-Стреды в одноэлектронном
приближении рассчитана холловская внутрислоевой проводимость в магнитном
поле, перпендикулярном проводящим слоям. Получены аналитические
выражения для амплитуд и фаз магнитных квантовых осцилляций (МКО) и
разностных (так называемых медленных) осцилляций (РО) и применены для
анализа их поведения в зависимости от нескольких параметров:
напряженности магнитного поля, интеграла межслоевого переноса и ширины
уровней Ландау. Также находим тензор магнитосопротивления вдоль слоев,
поскольку именно магнитосопротивление чаще всего измеряется в
экспериментах. Также исследуется поведение межслоевого
магнитосопротивления Rzz
в слоистых квазидвумерных металлах в углах Ямаджи, то есть углах наклона
магнитного поля, при которых наблюдается минимум межслоевой
проводимости. Рассматриваются случаи лоренцевой формы уровней Ландау и
формы, соответствующей самосогласованному борновскому приближению.
Теоретически предсказана зависимость Rzz∝B3/2в сильном поле, которая
согласуется с экспериментальными данными.
