Pyrolytic carbon for protecting soil macro-and mega-fauna

A protective agent for macro- and megafauna containing a hydrophobic pyrolytic carbon composition having a density of 1 to 3 g/cc, a carbon content of 95 to 100 weight-% and an ash content of 0.001 to 5 weight-%, wherein 85 weight-% of the carbon is not-functionalized and wherein the cation exchange capacity of the pyrolytic carbon is 0.001 to 0.75 cmol/kg.

A method to protect soil macro- and megafauna on agricultural fields which comprises applying hydrophobic pyrolytic carbon composition on the agricultural fields, wherein the pyrolytic carbon has a density of 1 to 3 g/cc, a carbon content of 95 to 100 weight-% and an ash content of 0.001 to 5 weight-%, wherein 85 weight-% of the carbon is not-functionalized and wherein the cation exchange capacity of the pyrolytic carbon is 0.001 to 0.75 cmol/kg.

Use of hydrophobic pyrolytic carbon composition having a density of 1 to 3 g/cc, a carbon content of 95 to 100 weight-% and an ash content of 0.001 to 5 weight-%, wherein 85 weight-% of the carbon is not-functionalized and wherein the cation exchange capacity of the pyrolytic carbon is 0.001 to 0.75 cmol/kg as protective agent for agricultural fields and/or gardening.

A method for controlling the presence of earthworms comprising applying hydrophobic pyrolytic carbon composition having a density of 1 to 3 g/cc, a carbon content of 95 to 100 weight-% and an ash content of 0.001 to 5 weight-%, wherein 85 weight-% of the carbon is not-functionalized, on a part of an area where presence of earthworms is desirable and leaving the other part of the area where the presence of earthworms is not desirable un-treated.
