Biochar activated charcoal for soil, coarse

Product detailed description

Revolution in your garden: A lasting investment in fertile soil

Imagine a soil amendment that you apply only once and then it improves the soil for hundreds of years, increases yields and saves you work with watering and fertilising. That is exactly Biochar – a stable form of carbon that acts as a permanent improvement for any substrate. It is not ordinary charcoal, but a high-tech product created by pyrolysis, which is the key to healthier plants and a richer harvest.

Key benefits of Biochar

• A soil sponge for your garden: Thanks to its extremely porous structure, Biochar works like a sponge. In light soils it absorbs and retains water, which it then gradually releases to the roots. For your plants, this means a constant supply of moisture even in drier periods, and for you less frequent watering.
• A magnet for nutrients: It prevents valuable nutrients from being washed out of the soil. Biochar binds nutrients from fertilisers and gradually makes them available to plants exactly when they need them. The result is more efficient fertilising and stronger, healthier plants.
• A luxury hotel for microorganisms: Billions of microscopic pores provide the perfect home and refuge for beneficial bacteria and fungi, such as mycorrhiza. In this way you support living, healthy soil, which is the basis of successful cultivation.
• Lasting aeration and structure: In heavy and clay soils, Biochar breaks up the compact structure, aerates the root zone and improves drainage. Plants therefore have ideal conditions for strong and healthy root growth.
• Natural detox and pH adjustment: It helps stabilise soil pH and can bind harmful substances or heavy metals, thereby preventing their uptake by plants. Your annuals, herbs and vegetables thus grow in a cleaner and healthier environment.

How exactly does Biochar work?

The secret lies in its incredible structure. Imagine Biochar as a huge coral reef on a microscopic scale. Every piece is interwoven with countless passages and chambers. These pores absorb water like a sponge while also providing a safe home for an army of beneficial microorganisms that live in symbiosis with your plants.

Unlike compost, Biochar does not decompose. Its structure remains stable in the soil for hundreds, if not thousands, of years. It is therefore a one-off application with an almost endless benefit for the health of your soil.

Step-by-step instructions for use

For maximum effect, it is essential to "charge" Biochar before use. Bare Biochar would initially take nutrients from the surrounding area for itself. Charging reverses this process and turns it into a nutrient reservoir.

1. Charging: Mix Biochar with quality compost, vermicompost (worm castings) or organic fertiliser in a ratio of roughly 1:1. Moisten the mixture and let it work for at least 1–2 weeks. During this time, the pores fill with nutrients and water.
2. Application to new beds and pots: Mix 10–20% of charged Biochar into the total volume of substrate or soil. Mix thoroughly so that it is evenly distributed.
3. Improving existing beds: Spread a layer of charged Biochar on the surface and gently work it into the top 10–15 cm of soil. The ideal dose is 5–10% of the volume of soil you are improving.
4. Adding to compost: By adding Biochar to compost (approx. 5–10% of the volume), you significantly speed up the maturation process, reduce any odour and the resulting compost will be much richer.

Why choose our coarse Biochar?

This fraction with a grain size of 1-25 mm is deliberately coarser, which brings specific advantages. It is ideal for maximum aeration of heavy soils, creating optimal drainage in growing containers and ensuring a long-term stable substrate structure. It is easy to work into the soil and is a perfect choice for establishing raised beds, growing more robust annual plants, tomatoes, peppers and much more.

Parameters

• Fraction: 1–25 mm
• Effect: Permanent (hundreds of years)
• Application: One-off
• Properties: Extremely porous, high cation exchange capacity (CEC)

Frequently asked questions (FAQ)

Is Biochar a fertiliser?
No, Biochar on its own is not a fertiliser. It works as a "carrier and reservoir" of nutrients.

How often do I need to apply Biochar?
Only once. Its structure is stable in the soil for generations, so it is a lasting investment in the quality of your soil.

Is Biochar suitable for organic cultivation?
Yes, absolutely. It is a 100% natural product that improves the soil without any chemicals and supports natural soil processes. It is the cornerstone of sustainable gardening.
