Abstract

The present invention relates to a process for the preparation of a composition containing a high content of boron and a dissolved humus compound that enhances boron uptake by plants.

Description

FIELD OF THE INVENTION The present invention relates to a process for preparing a composition containing a high content of boron and a soluble humus compound which enhances the boron uptake of plants.

Introduction

Intensive agricultural crops require an increased supply of nutrients, including trace elements. Among the micronutrients, wine plays an important role in certain cultures, especially in the case of sugar beet. The right amount of available boron, protects the plant from deficiency diseases and pathogens, increases the sugar content of beet sugar, and increases the amount of sugar that can be extracted from sugar beet. From the technological point of view, this boron is most advantageously available in a high concentration liquid so that the user can simply prepare the spray by pouring it into the tank and homogenizing it.

Humus compounds - and in particular the high-functional group (carboxyl, phenolic hydroxyl, carbonyl group) produced from fossil humic substances - have several beneficial effects on crop production. thus:

1. Stimulate membrane transport

2. As natural complexing agents, they enhance the uptake of micro and macro elements

3. They play a role in the degradation of xenobiotics, detoxification

4. Improve soil colloidal properties.

The use of humic compounds can reduce the amount of nutrients to some extent or achieve the same effect with the same amount of nutrients.

Thus, it is obvious to formulate a combination composition which contains the highest possible concentration of skin and an appropriate amount of a water-soluble humic compound (essentially potassium humate). For the sake of the user, this formulation should be both liquid and naturally stable.

Boron is essentially a complex compound of boric acid and its salts with various ethanolamine derivatives (monoethenolamine, etc.). These derivatives are liquid up to a certain concentration, only above this concentration the boric acid begins to precipitate and the product gels. Such articles are described in the embodiments described by Jáva Sava et al. However, these embodiments do not contain humic compounds that allow increased nutrient uptake.

The combined solution we propose is that a mixture of ethanolamines derivatives and liquid alkaline humates can produce mixed boron complexes which, on the one hand, contain high concentrations of wine and, on the other hand, the utilization of boron compounds is more beneficial due to the use of humus. This is due, on the one hand, to the membrane transport intensified by the humus compounds, to their role as a carrier, and, on the other hand, to the stabilization effect of the humus compounds in the soil, which reduces leaching.

A problem with the formulation of the combined formulation is that the humic compounds coagulate at high ionic strength and the product's utility is reduced. Therefore, the correct mixing sequence should be taken into account when developing the technology, and the use of anticoagulants may be advisable.

Implementation Examples

1. Into a stirred autoclave, add 200 kg of 12% potassium humate. To this solution add 230 kg of tap water and 288 kg of monoethanolamine under vigorous stirring for about 15 minutes. The solution should be homogeneous and free of flocs. 875 kg of solid boric acid are added to this solution with vigorous stirring. Homogenization results in a combined boron liquid boron composition containing 8% w / w boron.

2. To the above formulation is added 1 kg of potassium EDTA, which provides a multi-year stability of the product as an anticoagulant.

Claims (6)

Claims All combined implementations 1. characterized in that it comprises an organic complex of skin and / or boron at an elevated concentration and an alkaline humate. 2. Boron and humic acid are present in a user-friendly, highly manageable, concentrated liquid form. 3. The complexing agent is an ethanolamine derivative (mono-ethenolamine, etc.) 3. The concentration of boron in the product is between 1 and 14 m / m% 4. The concentration of alkali-humate is in the range of 0.5-5 m / m%. 5. In order to avoid coagulation of the components, the components are mixed in the following order: ethanolamine, alkaline-humane solution, boron compound. 6. The stability of the product is ensured by the use of an anticoagulant.
