SymSoil is an evidence-based, soil health company focused on Robust Compost products that reintroduce the entire soil biome.  The core team has training in the teachings of Dr. Elaine Ingham (SFW), Master Han Kyu Cho (KNF), and the practices of indigenous peoples and permaculture design. Co-composting with biochar, teaching conservation burns and farming soil microbes is central to SymSoil’s scalable approach to regenerative agriculture.  SymSoil has developed production at commercial scale of the complete, complex microbial community known as Soil Food Web, by optimization of nutrient exchange using biochar.

What is BIOCHAR?

Biochar is a solid material obtained from the carbonization of biomass.

It is a fine-grained, highly porous charcoal that enhances soil by retaining nutrients and water.

Customers use SymSoil as a biochar activator
 to enhance terrior. 

This is achieved through  reduced compaction, improved porosity, cation exchange, increased pH, retained water, improved hydaulic conductivity, promoted growth of microorganisms and
sequestered CO2.  ​​

Biochar 101

Biochar Improves the Environment by:
  • Reducing nitrous oxide emissions 50-80%
  • Reducing phosphorous and nitrogen in groundwater
  • Increasing soil carbon and reducing atmospheric CO2
  • Reducing forest fuel load
  • Sequestering carbon

Biochar by the bucket, yard or truckload   

We start with the best biochar we can find (and we search far and wide!). Then fully condition and colonize with the Symsoil biology, and ready for application, so it will boost the performance of even your best soil.

Fungal Infused Biochar   

Early versions of these products are available. We are seeking partners to test biologically active products designed for the saltier and more alkaline non-potable water, and the harsher environmental conditions associated with parking lots and asphalt heat deserts.

SymSoil, as a company, focuses on microbial diversity for soil health, and recolonizing native soil biomes and using biology to improve drought tolerance through soil porosity and water retention.

Biochar Classes in Northern California  

Join us in a class on how to create biochar with your farm's agricultural waste. As a service, SymSoil's team can come to your farm to do a burn or create compost.  We can create a sustainable process that works in your farm for future seasons.
