Annotation
Mixing brown coal from the Angren deposit, oxidised in an optimal mode with a mixture of nitric and sulphuric acids, with bentonite (from the Azkamar and Navbahor deposits) is a promising method for obtaining highly effective carbon-humic bentonite fertilizer. With a ratio of organic coal to bentonite from the Azkamar deposit of 100:10, a carbon-humic bentonite fertilizer was obtained containing 3.14% nitrogen, 73.20% organic matter, 54.92% humic acids, with a granule strength of 2.28 MPa and a moisture content of 5.2%, which does not cake and retains its friability even at higher moisture levels.
