Description
Biochar is a source of stable carbon with a rapid and direct affect on soil function. It will last in the soil for centuries and work to improve the water and nutrient holding capacity of soil. It is also one of the best tools we have for the remediation of salt or herbicide affected soils.
Biochar can also be used to improve poultry health as a feed additive or reduce ammonia and disease risk in coops.
Benefits of biochar in the soil:
- Promotes healthy root development by improving soil structure and drainage.
- Increases water and nutrient holding capacity of the soil
- Provides habitat for soil microbes that are essential for nutrient cycling and plant health.
- Improves saline or sodic soils by removing salts from the soil solution.
- Mitigates toxins by immobilizing heavy metals and pesticides and preventing plants from absorbing them.
- Reduces odors and pathogens in chicken coops and livestock pens.
INSTRUCTIONS FOR USE
Add biochar to the soil at a rate of 5-10% by volume. Like all carbon-based amendments, it is best to add biochar to the soil in the fall. For more about fall soil care, click here.
When used to improve soil health and function biochar must first be “primed” with nutrients and/or biology before adding it to the soil. This can be done with fish hydrolysate, compost extract, vermicast, compost, etc.
Make a slurry with the biochar and the product you will using to add nutrients and biology. Let this sit for a few days before using in your garden or landscapes.
When using biochar to remediate saline or contaminated soils, do not prime it. This will allow it to adsorb more salts or herbicide molecules from the soil.
