METHOD FOR INFLUENCING THE CONTENT OF COPPER AND ZINC IN SPRING RAPE PLANTS BY ORGANOMINERAL FERTILISERS Russian patent published in 2021 - IPC A01G7/00 A01C21/00 A01G22/00 

FIELD: agriculture.

SUBSTANCE: method includes introduction of a zeolite into the arable soil layer with introduction of mineral fertilisers into the surface layer of soil. Pure winter wheat is used as a precursor. Mineral fertilisers N₆₀P₆₀K₆₀ and organic fertilisers in the form of poultry droppings are introduced in doses from 2.5 t/ha to 10 t/ha, in combination with a zeolite at a dose of 3 t/ha in spring, after ploughing, during the period of agronomic workability of the soil. Harvesting is conducted after full ripening of rapeseed oil seeds, and the content of copper and zinc in the vegetative mass of rapeseed plants is determined in the rosette, flowering, pod formation phases, and in the harvesting phase.

EFFECT: method allows for a significant reduction in the concentration of copper and zinc in spring rapeseed plants.
