Catalyst Craft Compost

We’re passionate about compost and soil

At Catalyst BioAmendments, we’re composting nerds who don’t cut corners. Soil should be a thriving ecosystem on its own. That ecosystem is what keeps common problems for gardeners at bay. Weeds and harmful diseases that often plague plants are not an issue if the soil food web is intact, diverse, active, and balanced. We strive for perfection when it comes to creating compost, which is why we regularly check our compost with a microscope to ensure the soil life is diverse. (Want to see just how diverse? Check out our Instagram page!) The soil food web consists of many organisms, including:

• Bacteria
• Fungi
• Protozoa
• Nematodes

Our high-quality compost speaks for itself

We incorporate and grow many of our materials onsite, including our fungal inoculant. We start each wind row with the ingredients that we want to grow, and then keep the conditions perfect for them to thrive. Our end goal? Rich biological material that will make a dramatic difference in the lives of your garden or farm!

“Catalyst Bio-Amendments has been the most microbially active, diverse, and rich compost I have found to date. They have certainly put me and my gardens on the fast track to sustainable, productive harvests.” -Ahtifarms

We refuse to use green waste, biosolids, or industry byproducts when we create our compost. Cutting corners is not what we do here at Catalyst BioAmendments. We pay our producers well for our premium ingredients because we’re willing to put our money where our mouth is. In addition to checking windrows with a microscope, we also check the moisture levels. We ensure that no wind row gets too hot for too long, and we have ways to manage them in cases where the compost isn’t doing what it’s expected to do. We have learned much from working with compost and are excited to share great compost with you!
