METHOD OF PRODUCING CONCENTRATED FERTILISER FROM BIRD DROPPINGS AND CONCENTRATED FERTILISER

摘要

FIELD: agriculture.;SUBSTANCE: said bird droppings are mixed with water in a predetermined ratio to obtain a homogeneous mass; the obtained homogeneous mass is loaded to the dispersion chamber; the said dispersion chamber is sealed; the said homogeneous mass is heated to a predetermined temperature; the predetermined static pressure is fed into the sealed dispersion chamber; the contents of the said dispersion chamber is treated with ultrasonic vibration with insonification density of at least 60 W/cm², providing the sound pressure for a predetermined time on the said homogeneous mass, which exceeds the said static pressure by the predetermined value. The concentrated fertiliser from bird droppings with a particle size of not more than 30-50 nm.;EFFECT: inventions enable to obtain the concentrated fertiliser with nanoscale particles, to ensure the wide use of this concentrated fertiliser.;7 cl
