AGRO-TECHNICAL COMPOSITION WITH MAGNETIC PROPERTIES Russian patent published in 2021 - IPC C09K17/40 C05F11/02 

FIELD: agriculture.

SUBSTANCE: agro-technical composition is proposed containing ground brown coal and ground ultrabasic (alkaline) material. It contains ground natural serpentine as ultrabasic material at the mass ratio with ground brown coal from 0.6 to 1.3. It additionally contains natural clay at the mass ratio with ground brown coal from 0.1 to 1.0. Magnetite included in the composition of the specified ground natural serpentine has magnetization of at least 80% of the saturation level obtained in the result of the exposure of the magnetic field to the ground natural serpentine or agro-technical composition as a whole.

EFFECT: providing the possibility of preserving nutritional elements in the soil while using the composition with simultaneous eliminating the use of components poisoning the soil with obtaining indicators of agro-technical efficiency typical for black soil, as well as creating the magnetic field by the composition when using it, which can affect both the nutritional elements of the soil and plant seeds, and plant itself during the growing season.
