STUDY DEMONS­TRATES WHY CO-COMPOSTED BIOCHAR PROMOTE PLANT GROWTH

An inter­na­tional team of rese­ar­chers has examined the under­lying mecha­nisms of how biochar (pyro­lized biomass) becomes a potent ferti­lizer. Because: Biochar is not equal to biochar. The carbo­nates promote plant growth and stimu­late soil ferti­lity only when combined with nutrient-rich organic matter, e.g., co-composted biochar. The scien­tists there­fore tested biochar before and after compos­ting with manure.

Their results: The rese­ar­chers iden­tify a complex, nutrient-rich organic coating on co-composted biochar that covers the outer and inner (pore) surfaces of biochar parti­cles. This implies that the func­tio­ning of biochar in soil is deter­mined by the forma­tion of an organic coating.

    BIOCHAR: Approval for organic farming throughout the EU

    Biochar may now be used throughout Europe in organic farming as a fertilizer/soil conditioner. What a breakthrough! In Germany, for example, biochar has so far only been allowed to be used in the form of charcoal in agriculture. But now, in...
