Regenerative Compost, Delivered
Every week, Fallen Oak produces over 25,000 pounds of organic, nutrient-rich mushroom compost—a powerful catalyst for soil regeneration and ecological healing. This isn’t waste—it’s the living byproduct of our commitment to circular systems and regenerative agriculture.
Our compost is now available in a more impactful way: delivered directly to your farm in 10-yard trailer loads. Whether you're rebuilding tired soil, boosting biodiversity, or scaling sustainable practices, this service brings the full power of our compost straight to your land.
For smaller needs, we continue to offer free pick-up of up to 50 spent blocks on designated days.
This program is part of our deeper mission: to “Think Like a Mushroom”—to transform waste into life, cultivate resilience, and regenerate the ecosystems beneath our feet.
