“Biochar may represent the single most
important initiative for humanity’s
environmental future. The biochar approach
provides a uniquely powerful solution, for it
allows us to address food security, the fuel
crisis, and the climate problem, and all in an
immensely practical manner. ”
Prof Tim Flannery
2007 Australian of the Year

“I sent off another truckload of calves
today, lovely animals. No fertilizer, yet
more fertile soil than last year! No hay!
No drenches! No red legged earth mite
spray! No lucerne flea spray. Lovely soft
water-absorbing soil! Economic no
brainer!”

POTENTIAL BENEFITS OF BIOCHAR IN SOIL
Physical
• Increased water holding capacity of the soil
• Improved structure and consistency of the soil
Chemical
• Increased soil carbon levels
• Increase in pH (liming effect)
• Increased CEC, especially over the long-term
Biological
• Improved microbiology of the soil
• Improved conditions for earthworms
Toxicity waste
• Decrease toxicity: Aluminum, Cadmium, DDT, PAHs
• Decrease leaching of nutrients
• Decrease emissions of greenhouse gases CO2, N2O & CH4
Economics
• Increased fertilizer use efficiencies• Increased biomass (crop) production
NB Varies with
feedstock, process,
soil type and crop
species.
Greatest benefits in
degraded, acidic or
nutrient-depleted soils

Biochar
• Activated by microbes through cow rumen
• Additional microbes via Bubas bison gut
• Moisture laden
• Soaked in nutrients, especially P and N
• pH buffer
• Lowers soil bulk density
• Habitat for soil microbiology, including mycorrhizal fungi – enhances symbiosis

Biochar and Zeolite (Dr David Tomlinson – Castlemountain Zeolite)
Early stages of trial
Cattle and sheep readily consume mix of biochar and zeolite, with added molasses
• Better animal performance
• Reduction in methane produced
Currently in drought but expect (as a result of holistic grazing, biochar and zeolite
and dung beetles burying the medicated manure):
• Higher digestibility of higher nutrient density pasture
• More sequestered carbon
• Compounding effect of further reduction in methane
• Extra carbon that will improve water infiltration and storage

Synergies of Biochar and Zeolite Dr David Tomlinson (Castlemountain Zeolite)
Milled and ground to fine powder:
• More growth (breaks down N in gastro-intestinal tract)
• Less N exceted
• Better digestion
• Reduces ammonium toxicity
• Reduces respiratory distress in confined animals
• Chelates minerals
• May bind fungal toxins
• Binds heavy metals
• Binds some water eg in slurries
• Microbial habitat
• Less odour
• Fewer flies
• More solid dung pads
• Quicker dung beetle incorporation
• Reduced pig scouring
• Effective in intensive livestock production
