Problems solved by technology

In polluted systems, these acids are gradually depleted and their bioavailability decreases
[0021] Other combinations addressed in the literature also do not employ bioavailable forms of silicon and do not take advantage of the synergistic effect of boron on the bioavailability of non-colloidal silicon

Embodiment

[0055] Experiment 1: The effect of boron on the toxicity of silicon:

[0056] In our experiments, salad plants (head lettuce ( cobbage lettuce)) for two weeks. Potassium silicate was used as the Si source. Solutions were prepared fresh; unfiltered. Vegetative growth stops completely and the plants become very stiff. Adding 0.001% of boron in the form of boric acid to this silicic acid reduced the toxicity (growth) mentioned above, but the plants were still stiff. A control experiment using only 0.001% boron in 5% propylene glycol showed no effect (control). This shows that boric acid is involved in the metabolism of silicic acid, and the ratio of Si / B is very important.

[0057] Experiment 2: Antimicrobial activity of boric acid with and without silicon

[0058] Aqueous solutions of boric acid were prepared containing different concentrations of boric acid: 1%, 0.1%, 0.03%, 0.01%, 0.005%, 0.0003% and 0.0001% (W / V).

[0059] Sodium silicate (10% Si) was diluted 10 times ...

Abstract

The present invention includes an aqueous solution, comprising boric acid and non-colloidal silicic acid. This solution can also comprise a water absorbing additive. The solution contains bioavailable non-colloidal silicic acid, and the solution is stable for more than one year. The invention also describes 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 dissolved water absorbing additives.

Description

technical field [0001] The present invention relates to aqueous solutions containing bioavailable silicon and boron, which can be used for strengthening plants or trees, or as dietary and feed additives for humans and animals. The invention also relates to the preparation of stable solutions containing bioavailable silicon and boron. Background technique [0002] Silicon is an essential nutrient for plants, and silicon with low concentration of orthosilicic acid (H 2 SiO 4 ) are present in soil, minerals and seawater. In modern agricultural systems, nutrient solutions are most deficient in orthosilicic acid, and added silicates cannot compensate for this deficiency. Silicic acid is sometimes added to nutrient formulas but is not sufficiently bioavailable because silicates are poorly soluble in water. [0003] Silicates are not easily absorbed by organisms. Orthosilicic acid is preferably the most bioavailable silicon compound for diatomes, plants, animals and humans. I...
