A natural soil boosting blend designed specifically to improve soil health without the need for synthetic chemical additives.

OurCarbon™ biochar, the heart of the DEN soil and fertilizer blends, is a charcoal product made through the pyrolysis of organic matter diverted from landfill. Used to draw down carbon from the atmosphere as well as ameliorate and enhance soil activity, a little goes a long way. This container of natural fertilizer represents 18 lbs. of sequestered carbon.

The mini, which is a great tester size, aids up to 6 cups of soil, and the large aids up to 66 cups of soil.

Northern California-based DEN Soils is on a mission to clean up the dirty commercial soil industry. With entirely natural and locally sourced ingredients, as well as plastic-free, compostable packaging, their soils are the perfect base for indoor planting and outdoor gardens of all kinds.

Made in Northern California from local, California-based ingredients.
