Abstract

Official abstract text for this publication.

Carbon black can be used for soil conditioning, e.g. to promote growth of plants, to promote soil drainage, and to prevent erosion, evaporation, and silting up. The carbon back is worked into the topsoil.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A process of soil conditioning, including: (i) providing 2 to 500 tons/ha of hydrophobic carbon black on a topsoil of an agricultural field, and (ii) working the hydrophobic carbon black into the topsoil. 2 . The process according to claim 1 , wherein the hydrophobic carbon black is worked into the topsoil to a soil depth of at least 3 cm. 3 . The process according to claim 2 , wherein the hydrophobic carbon black is worked into the topsoil homogeneously. 4 . The process according to claim 1 , wherein the hydrophobic carbon black is worked into the topsoil up to a soil depth of 10 cm. 5 . The process according to claim 1 , wherein a carbon content of the hydrophobic carbon black is 95 to 99.5 weight-%. 6 . The process according to claim 1 , wherein the hydrophobic carbon black is a hydrophobic material with a contact angle of water droplets of greater than 70. 7 . The process according to claim 1 , wherein 5 to 20 tons/ha of the hydrophobic carbon black are provided on the topsoil of the agricultural field. 8 . The process according to claim 1 , wherein a particle size of the hydrophobic carbon black is 1 nm to 1 μm. 9 . The process according to claim 1 , wherein pellets of the hydrophobic carbon black have a particle size of 0.3 to 8 mm. 10 . The process according to claim 1 , wherein the hydrophobic carbon black supports at least one different organic or inorganic additive. 11 . The process according to claim 1 , wherein a carbon content of the hydrophobic carbon black is 80 to 99.8 weight %.
