Granular potassic fertilizer with prolonged action, based on ash from burning a biomass and method for producing the granular potassic fertilizer with prolonged action, based on ash from burning a biomass

摘要

the object of the application is granular fertilizer potassium prolonged action based on incineration ash of biomass, in which fertilizer potassium content calculated as k2o contains in the range of 5 to 20% by weight. this is dried at a temperature to fertilizer granules 200u00b0c, moist mixture or pulp containing at least the ash from the combustion of biomass, in quantities of not less than 50 wt%.as the finished product, sulphuric acid, 30% to 98% in quantities of from 50 to 300 g per 1 kg of h2so4 incineration ash of biomass, and also possibly products which contain potassium in the form that is available to be used by the plants, with the particle size of granules is 1 to 6 mm, and the ph odci they're waiting aquatic with finished product is 4.5 to 9.in the production of potassium fertilizer was also revealed a prolonged action based on incineration ash of biomass, including the formation of granules in granulatorze mechanical torque from a mixture containing ash from biomass burning and drying the formed granules k.
