THE PROCESS

Here at Carbon and Soil, we use a high carbon-to-nitrogen ratio of 140:1 as the feedstock input. The 140:1 ratio will have a higher fungi count and other living soil microorganisms.

Carbon and Soil uses passively aerated static composting as our pre-composting method. Our feedstock consists of wood chips, shredded paper,  and cardboard. Instead of using fruit and vegetable material as the nitrogen side of composting, we mainly use comfrey and stinging nettle for their diverse nutritional and nitrogen value. We also use kelp meal for additional nutrient value in the pre-compost method. After the decomposition period, we feed the mix to our worm bins. To help the cellulose, lignin, and inks break down, we inoculate oyster mushroom mycelium in the pre-compost bin. 

 

We produce our vermicompost outdoors year-round in modified compost bins with shade cloth, as bunker-style worm bins, and wooden troughs.   
​

To be efficient in producing an end product, we use various compost worms, a mix of redworms(Eisenia fetida and Eisenia Andrei), European Nightcrawlers(Eisenia Hortensis), Blueworms (Perionyx Excavatus), and Jumpers(Amynthas Gracilus). 

After 24 to 48 weeks of vermicomposting, we harvest the finished vermicompost and screen it at 1/8" for water solubility.
