METHOD FOR INCREASING SOIL FERTILITY AND PRODUCTIVITY OF SPRING RAPE Russian patent published in 2022 - IPC A01G22/00 C05F3/00 C05D9/02 

FIELD: agriculture.

SUBSTANCE: method of increasing soil fertility during cultivation of spring rape is characterized by the fact that chicken droppings of the following composition are introduced: total nitrogen — 26 g/kg, phosphorus — 9 g/kg, potassium — 2.6 g/kg; wt.%: Na — 1.5; Mg — 5.5; Al — 0.5; Si — 2.8; K — 5.9; Ca — 11.9; mg/kg of dry weight: Fe — 43.75; Co — 0.67; Ni — 1.79; Zn — 22.39; Cu — 5.0; Mn — 126.68; Pb — 0.26; Cd — 0.06, in dose of 5 t/ha to 10 t/ha in pure form with simultaneous introduction of natural zeolite, having sorption capacity with respect to heavy metals and having the following composition, wt.%: Na — 0.1; Mg — 0.9; Al — 9.4; Si — 21.3; K — 1.6; Ca — 0.8, in dose of 3 t/ha in pure form, in spring at the end of the third decade of April, sowing is carried out with soil heating to 8–10 °C with a seeding rate of up to 2.5 million pieces/ha of germinating seeds, spring rape is harvested by direct combining.

EFFECT: invention makes it possible to increase intensity of spring rapeseed growing for seeds.
