The Sacred Soil Starter from the Biodynamic World
In an age of synthetic shortcuts and quick fixes, there’s something deeply grounding about returning to ancient rhythms—of land, moon, manure, and time. One such practice is Preparation 500, better known as Horn Manure.
It may sound old-world, even mystical—and it is. But it’s also one of the most powerful, low-cost, and deeply effective soil activators available today for gardeners, organic growers, and mindful farmers.
Let’s break down what Prep 500 is, how it works, and how you can use it in a modern setting without losing its soul.
🌕 What Is Prep 500?
Prep 500 is a biodynamic soil enhancer that brings structure, vitality, and microbial life back into depleted soils. It was introduced by philosopher and scientist Rudolf Steiner in 1924, as part of a broader system called biodynamic agriculture—a spiritual-ecological approach to farming that views the land as a living organism.
In essence, Prep 500 is cow manure fermented underground in a cow horn over winter, then stirred in water and sprayed across the soil in droplet form. But this is no ordinary compost—it’s a ritual, a remedy, and a reconnection.
🐄 How Is It Made?
The Original Method (Still Used Today)
-
Fresh cow manure (from pasture-fed cows) is packed into clean, hollow cow horns.
-
These horns are buried about 40–60 cm deep in undisturbed, living soil at the start of autumn.
-
They remain underground through the entire winter, absorbing the earth’s seasonal energies and transforming microbially.
-
In spring, the horns are dug up and the contents—a rich, crumbly, sweet-smelling humus—are collected.
-
The result is Prep 500—a microbial and energetic activator unlike anything synthetic agriculture has ever made.
💧 How to Use Prep 500 (Modern Instructions)
| Step | Details |
|---|---|
| 🔄 Stirring | Stir 25g (about a heaped tablespoon) in 13–15L of rainwater for 1 hour, alternating clockwise and anti-clockwise to create a vortex, then chaos. This “dynamisation” energises the water. |
| 🌇 When to Spray | Late afternoon or early evening is best. Avoid strong sun. |
| 🌙 Moon Timing | Apply during the descending moon phase, especially on Earth signs (Taurus, Virgo, Capricorn) for grounding and root energy. |
| 🌾 Where to Apply | Lightly flick or spray over bare soil, not on leaves. Cover the whole area you want to boost. Ideal for pre-planting soil health, orchard floors, veggie beds, and even pastures. |
🔔 Tip: You only need 25g per hectare—yes, it’s that potent.
🌱 Why Use Prep 500 in Modern Times?
Even if you don’t follow every biodynamic principle, Prep 500 offers incredible benefits:
-
Activates soil life – waking up beneficial bacteria and fungi
-
Strengthens root growth – deeper roots = better drought resistance
-
Improves soil texture – more crumbly, airy, and water-retentive
-
Restores natural balance – reducing the need for artificial inputs
-
Connects you to seasonal rhythms – farming with, not against, nature
And for those who value intuition, spirituality, or Eastern wisdom—Prep 500 mirrors yoga for the soil, or Qi Gong for your garden beds. It’s an energy practice, not just a fertiliser.
🔮 Modern Growers Are Returning to Ancient Practices
From permaculture farms to boutique vineyards and backyard veggie patches, growers are rediscovering the deep intelligence of biodynamics. Prep 500 is leading that revival.
It’s the ultimate slow-and-steady tool in your soil toolbox. It doesn’t force growth—it supports and awakens the soil’s own ability to thrive.
Whether you’re into lunar calendars, intuitive planting, or simply healthier crops and stronger yields, Prep 500 brings harmony and health from the ground up.
🧘 Final Thought
Prep 500 teaches us that true fertility isn’t something you buy in bulk bags. It’s something you nurture, stir, and co-create with the forces of nature.
If you’re looking for a more grounded, seasonal, and spiritually attuned way to grow—Prep 500 might be your gateway.
