| 摘要 |
Disclosed herein is an aqueous solution, comprising boric acid, non-colloidal silicic acid and a water absorbing additive, wherein silicon as silicic acid is present between 0.01 and 2 wt. % and boron as boric acid is present between 0.0001 and 4 wt. %, wherein the solution has a pH-value below 2. This solution contains bioavailable silicon (in the form of non-colloidal silicic acid and boron (in the form of boric acid) that can be used to strengthen plants or trees, or as food or feed additives to humans and animals, and the solution is stable for more than a year. A method for the preparation of a solution in which one or more silicon and boron compounds are hydrolysed in an acidic solution containing one or more solved water absorbing additives is also disclosed.
