Key Features
- Improves Nutrient Holding Capacity: Biochar has a high cation exchange capacity (CEC), which helps to hold nutrients within the compost, preventing them from leaching away with water movement. This makes nutrients more available to plants for longer periods.
- Enhances Microbial Activity:Our Compost Mix provides a habitat for beneficial microorganisms. These microbes are essential for the breakdown of organic matter into nutrients that plants can use. The porous structure of our product provides protective sites for these microbes, which can enhance the composting process and improve the microbial life of the soil when applied.
- Improves Soil Structure: When combined with compost, biochar can help improve soil structure. It can reduce density, improve aeration and water infiltration, and help create a more favourable environment for root growth.
- Increases Water Retention: Biochar can significantly increase the water-holding capacity of the soil. When mixed with compost, which also has good water retention, the blend can help soils maintain moisture for longer periods, which is crucial for plant health, especially during dry spells.
