water the rest. Hydroxyethylidene diphosphonic acid is introduced into the fertilizer as a dipotassium salt with a pH of 4.0-4.0. The proposed composition of CMU can be used in crop production, agrochemistry, research on plant physiology, photo- and biosynthesis. 1 hp f-ly, 2 tab.

Description

in dry low wind weather,; Accounting for the influence of the use of the CMU provostili-in terms of the content of gluten in the grain. The repetition of experiments is threefold.

Example 1. Processing the crop was performed CMU composition 1.

Soil: typical chernozem carbonate thick with a content of assimilable phosphorus of 14.0 mg, potassium 8.3 mg per 100 g of soil. The humus content is 3.7%. pH 7.0.

Example 2. Processing was performed CMU composition 3.

Soil: typical black carbonate black soil with 14.0 mg of absorbed phosphorus, 8.3 mg of potassium per 100 g of soil. The humus content is 3.7%, pH 7.0.,

Example 3. The treatment was conducted CMU-composition 2.

Soil: typical chernozem carbonic, powerful with a content of assimilable phosphorus of 15.9 mg, potassium 8.8 mg per LLP g soil Content of humus is 3.2% pH 7.5.

The test results for the content of raw gluten in grain, winter wheat are given in table. 2.,

Ktiy is prepared by mixing components. Hydroxyethylene diphosphonic acid is introduced in the form of dicalium salt or pH of the solution, adjusted to 4-5 with an alkali.

From tab. 2 it follows that the content of raw gluten in the grain is maximally increased in the experiment of Example 3, corresponding to the optimal composition of CMU. The increase in raw gluten content in this case is 2.1%. The maximum and minimum concentrations of trace elements in examples 1 and 2 correspond to a slight increase in the effect.

Changes in the direction of decreasing or increasing concentrations of the injected components of magnesium sulphate and hydroxyethylidene diphosphonic acid do not allow to achieve this goal of the invention: a decrease in the indicated trace element dosages leads to a decrease in the agrochemical effect, smart | - the amount of hydroxyethane added with lidandiphosphonic acid does not allow to obtain a stable homogeneous solution, i.e. leads to a deterioration in the quality of CMU.

An increase in the micronutrient dosages of magnesium and hydroxyethylidene diphosphonic acid does not give a significant improvement in product quality (the content of raw gluten in the grain) with a significant increase in costs, which is not economically feasible.

The proposed CMU is a clear aqueous solution with a pH of 4-5, containing a set of trace elements in a highly soluble state, which determines its effectiveness with the help of serial technology.

As follows from the experimental data, the application of the proposed CMU has had an impact on the quality of the grain, namely, an increase in its gluten content to 20–21%. This effect is not only due to the improvement in the quality and stability of the CMU compound, it cannot be satisfactorily explained from the standpoint of chelate formation, since the CMU prototype was used in comparison experiments with carbamide possessing complexing properties.

Obviously, in the proposed case, the effect is achieved by a combination of effects due to the synergism of the action of shlkroelementy in the proposed composition and the inherent biological activity of hydroxyethylidene diphosphonic acid, which has an effective effect on increasing the gluten content in the grain.
