Method of Production of a Soil Conditioner and the Soil Conditioner Produced by the Method

A method of production of a granulated soil conditioner based on a mixture of biochar and organic fertiliser, wherein the conditioner is endowed with bacteria, mycorrhizal fungi and myco-parasitic fungus, wherein the method comprises:

• mixing the biochar obtained by thermal reduction of plant biomass or animal bones with animal excrements in the weight ratio of 1 part of biochar to 0.1 to 0.4 part of the excrement dry matter, mixing to this base a compound of soil bacteria including at least two of the group of:
• Rhizobia genus bacteria,
• nitrification bacteria of the Azospirillum or Azotobacter genus,
• Pseudomonas genus bacteria, and
• Bacillus genus bacteria,
• wherein the weight of their dry matter at the concentration of CFU 109 being 0.2 to 0.5% of the base dry matter weight,
• topping the bacteria-endowed base up with water in the weight of not more than double the weight of the bacteria-endowed base and letting it ferment for at least 5 days,
• draining off the excess water and drying the base with bacteria for the water content not to exceed 20 wt %, thereupon adding to the base-bacteria compound a mixture of fungal spores including at least two of the group of:
• Trichoderma, arbuscular mycorrhizal fungi, ectomycorrhizal fungi in a total amount corresponding to 0.2 to 1% of the base-bacteria compound dry matter weight, and
• thereupon mixing the thus prepared mixture profoundly.
