Abstract
The invention relates to an aqueous solution consisting essentially of: (a) hydrogen peroxide; (b) at least one compound selected from the group consisting of complexing agents based on phosphonic acids, salts and degradation products thereof in an amount from about 10 to about 60 wt % based on the amount of hydrogen peroxide; (c) water; and (d) components other than (a) through (c) in an amount from 0 up to about 10 wt % based on the amount of hydrogen peroxide The invention further concerns a soil oxygenation or micronutrient composition comprising hydrogen peroxide, a process for its preparation, and a process for the oxygenation of soil.
