Biocarbon in Soil Treatment

Biocarbon, applied in combination with organic and inorganic fertilisers in agriculture, has been shown to stimulate microbial growth in unaltered soils to increase nutrient availability and related ecological functions.
Millions of pores created through the process of pyrolysis gives Biocarbon a high adsorption surface area. Macro- and mesopores promote aeration while micropores advance molecule adsorption and transportation, making it an ideal habitat for the microbial community to thrive.

Biocarbon remains active in soils for millennia and retains applied nutrients more than other organic matter, slowly releasing it to growing plants. There is no better alternative for water retention in sandy soils, while Biocarbon’s liming effect in acidic soils improves fertility and structure through microbial diversity.

Aeration and water retention can be enhanced by adding Biocarbon to clay and lumpy soils. It’s porous nature and soil aggregation also reduce the bulk density of soils. When oxidised, Biocarbon’s hydrophobic property increases water absorbance and holding capacity, making it ideal for improving soil quality in cultivating areas prone to drought.
The higher organic carbon content of Biocarbon’s facilitate enhanced crop harvests and mitigates greenhouse gas emissions. Potassium, calcium, and magnesium in Biocarbon can decrease exchangeable aluminium and hydrogen ions through adsorption and improve soil pH.
The higher cation exchange capacity (CECs) of Biocarbon promotes plant growth through nutrient fixation. In general, Biocarbon increases soil fertility and limits offsite pollution while it decreases soil leach-out of applied nutrients by retaining them.
