Treatment of irrigation water and solutions of mineral fertilizers in a magnetic field gives the opportunity to increase the yield of crops, reduce the incidence of plants, improve the quality of products and improve the use of mineral fertilizers.
But the lack of explanation of the effect of the magnetic field on processes occurring in aqueous solution does not make it possible to establish all the factors in its treatment in a magnetic field and to determine their optimal values.
Irrigated water, nourishing and cellular solutions are multicomponent solutions of electrolytes. Therefore, theoretical and practical interest is the study of the change in the specific electrical conductivity of such solutions under the action of a magnetic field.
The purpose of the study is to determine the influence of a magnetic field on the specific electrical conductivity of aqueous solutions.
Experimental studies of the change in the specific conductivity for processing aqueous solution in a magnetic field were carried out with a solution of the following composition: ammonium nitric acid - 11,36 g/l; sodium nitric acid - 0,12 g/l; potassium sulfate - 1, 56 g/l; calcium phosphate - 6,6 g/ ; magnesium sulfate, - 1,05 g/l.
The solution was passed through a magnetic field created by permanent magnets from the NdFeB intermetallic composite. The magnetic induction was controlled by changing the distance between the magnets and measured with a tetrameter 43205/1. The speed of the solution was 0.4 m/ , and the temperature was 20 ° C.
Specific electrical conductivity was determined before the magnetic treatment of the solution and after it with a laboratory conductivity meter КЛБ-1M.
Under the action of a magnetic field, the degree of electrolytic dissociation increases. As a result of changing the coefficient of electrolytic dissociation under the influence of the magnetic field, the specific electrical conductivity of the solution changes.
As a result of changes in magnetic induction from 0 to 0,065 T, the specific electrical conductivity of aqueous solutions increases, and for further increase of magnetic induction begins to decrease.
The change in the specific electrical conductivity of the solution for magnetic processing depends on the square of the magnetic induction and the speed of motion dissolved in the magnetic field. The most specific electroconductivity of the solution increases with a magnetic induction of 0.065 T and a flow velocity of 0.4 m/s. Magnetic treatment of aqueous solutions improves the solubility of substances contained in it.
