BuildASoil Biochar Soil Amendment

Raw biochar can actually strip nutrients from your soil initially as it settles. Pre-charging means this product has already been infused with microbes and amino acids, so it starts working immediately to support your plants rather than competing with them for nutrients.

This is perfect for existing containers. Because it is no-till friendly, you can simply top-dress your pots or gently mix it into the top few inches of your soil to revitalize tired growing media without disturbing established root systems.

The recommended mix rate is 2–5% of your total soil volume. For most home gardeners, this means adding a small handful per gallon of soil is sufficient to see improvements in aeration and moisture retention.

Biochar generally has a slightly alkaline pH, but because this is a pre-charged amendment designed for integration at a low percentage (2–5%), it is unlikely to drastically shift the pH of a balanced soil mix. It is safe to use across all soil types.

No, this is a soil amendment, not a fertilizer. While it contains microbes and amino acids that help biological activity, you should still maintain your regular feeding schedule to ensure your plants get the necessary macronutrients.
