Abstract: Soil conditioning substrate containing granular pyrolytic carbon having a density of 1.6 to 2.3 g/cc, a specific surface area of 0.001 to 5 m2/g measured by Hg porosimetry, a particle size of 0.3 mm (d10) to 8 mm (d90) and a carbon content of 95 to 100 weight-%. A method to promote growth of plants on agricultural fields which comprises applying particulate granular pyrolytic carbon having a density of 1.6 to 2.3 g/cc, a specific surface area of 0.001 to 5 m2 / g measured by Hg porosimetry, a particle size of 0.3 to 8 mm and a carbon content of 95 to 100 weight-%. Use of granular pyrolytic carbon containing granular pyrolytic carbon having a density of 1.6 to 2.3 g/cc, a specific surface area of 0.001 to 5 m2/g measured by Hg porosimetry, a particle size of 0.3 mm (d10) to 8 mm (d90) and a carbon content of 95 to 100 weight-% as soil conditioner for agricultural fields and/or gardening, carbon content of 95 to 100 weight-% on the agricultural fields.
