    Study Notes

    Organic Agriculture Principles

    • Biodynamic farming is a holistic, ecological, and ethical approach to farming, initially developed by Rudolf Steiner.
    • This method focuses on strengthening the interaction between soil, plants, animals, and humans, creating a living organism where each part supports the other.

    Biodynamic Preparations

    • Horn Manure (500): A preparation involving filled animal horns
    • Horn Silica (501): A preparation involving animal horns
    • Stirring and Spraying Horn Manure and Horn Silica Preparations: A method for preparing and applying Horn Manure and Horn Silica
    • Biodynamic Preparations (general): Illustrative images of various plants and a horn are shown, suggesting diverse preparation methods are used.

    Yarrow Preparation (502)

    • A biodynamic preparation made from yarrow flowers.
    • The flowers are packed into a stag's bladder.
    • The bladder is hung in sunlight during summer.
    • In autumn, the bladder is buried in fertile soil, remaining there over winter before being retrieved in spring.
    • The yarrow plant is related to Venus and solar energies, high in sulphur and potassium, and recycles urea into protein to stimulate soil.
    • A stag's bladder is used because of the animal's natural detoxifying and cleaning processes.

    Chamomile Preparation (503)

    • Made from German Chamomile.
    • Flowers are placed in the intestine of a cow in autumn.
    • The best time for collecting young chamomile flowers is early summer in the early morning.
    • A 30–40cm length piece is knotted at one end, and a large funnel is used to place chamomile flowers inside the tube before knotting the other end.
    • Historically used for digestion and preserving meat in pre-refrigeration times. Biodynamically, it reduces soil ammonia, breaks down organic matter, increases calcium, and builds rich humus soil.

    Sting Nettle Preparation (504)

    • The preparation is made in autumn.
    • Dried nettles are compacted into 10-15 cm clay pots, placed head-to-head in fertile soil, and left for a year.
    • Over the following 12 months, the nettles transform, leaving dark colloidal humus.
    • This preparation is related to Mars, aiding soils with imbalanced iron, magnesium, and sulphur.

    Oak Bark Preparation (505)

    • Made by filling a domestic animal skull (cow, sheep, or goat) with finely ground oak bark.
    • The skull is buried in a watery environment in autumn.
    • The preparation is lifted in spring and undergoes a final aerobic process.
    • Oak bark contains approximately 3-5% calcium (natural plant-based “living” calcium).
    • Skulls are used because they are linked to sensory and nervous systems (intelligence), and are made of calcium-rich bone, a vessel to regulate and balance calcium levels.

    Dandelion Preparation (506)

    • Dry dandelion flowers are placed within a cow's mesentery (sheath or skin surrounding internal organs).
    • It is folded like a parcel, sewn, and buried in autumn.
    • Dandelions significantly influence plant and soil life's access to silica, crucial for improving cell structure and smooth plant sap flow.

    Valerian Preparation (507)

    • Unlike other preparations, Valerian flowers are not dried but milled into a paste using a pestle and mortar.
    • The crushed flowers are mixed with water and placed in a glass jar in light.
    • Valerian is related to the effects of light and warmth, stimulating soil micro-life for phosphorus availability.

    Cow Pad Pit (CPP) (502,507)

    • Promotes organic matter breakdown into humus in soil, compost, and manure.
    • Improves soil structure and water retention.
    • Made from a mixture of 60 kg cow manure, 200 g crushed egg shells, and 300 g basalt dust.
    • Mixed ingredients are fermented for three to four months in a brick-lined pit.
    • Selection criteria for the pit include well-aerated, shaded site not interfering with plant roots.
    • Pit dimensions: 90 x 60 x 30 cm.
