MICRONIZED EARTH ALKALI CARBONATE-CONTAINING MATERIAL FOR REGULATING THE PH OF A SOIL |
| 摘要 |
The present invention relates to a method for regulating the pH of a soil as well as the use of at least one earth alkali carbonate-containing material having a weight median particle size d50 value of ≦50.0 μm for optimizing or improving the pH of a soil as well as the use of an irrigation or spraying system for the application of an aqueous suspension comprising at least one earth alkali carbonate-containing material in order to optimize or improve the pH of a soil. |

1. A method for regulating the pH of a soil, the method comprising the steps of:
a) providing at least one earth alkali carbonate-containing material having a weight median particle size d50 value of ≦50.0 μm, b) providing an aqueous solution, c) contacting the at least one earth alkali carbonate-containing material of step a) with the aqueous solution of step b) such as to form an aqueous suspension comprising the at least one earth alkali carbonate-containing material, and d) applying the aqueous suspension obtained in step c) on and/or into soil through an irrigation or spraying system, wherein the aqueous suspension is applied on and/or into the soil in an amount from 1.0 to 250.0 kg/ha, based on the at least one earth alkali carbonate-containing material per pH increase of 0.1 of the soil. |
