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 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

Fungal Infused Biochar

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.
