Description
Manufacturing method of encapsulated organic and mineral fertilizer, with an extended action, in granular form
Manufacturing method of encapsulated organic and mineral fertilizer, with an extended action, in granular form from lignite crushed to fraction size up to 1 mm. The organic and mineral fertilizer, encapsulated with an extended action, in granular form, manufactured using the method according to the invention aims to decrease the negative impact of chemical compounds on the soil and increase of usage of minerals contained in it through the slower decomposition of mineral fertilizer granules in the soil.
Over 70 years old usage of the mineral fertilizers for an industrial scale causes soil degradation through the significant increase in salinity, decrease of acidity, disappearance of biological life and decrease of the permanent content of nutrient humus. So far, attempts have been made to counteract the degradation of arable soils by using natural or organic fertilizers, most often in the form of manure or compost, the availability of which is significantly limited. However, this treatment is very expensive and it is true that it brings some nutrients and nutrient humus to the soil, but in intensive crops it did not protect from the loss of the permanent humus and disappearance of biological life. In state of the art there are known different manufacturing methods of organic and mineral fertilizers.
From the patent application description US 2013104612 Al it is known a method of obtaining phosphate compounds comprising reaction of a source of insoluble phosphate with an organic source, principally of vegetable origin, optionally in the presence of a mineral acid or an organic acid, said organic source having at least 10% of complexing functional groups.
From the patent application description US 2013310711 Al it is known an organic mineral fertilizer composition containing an inorganic matter supply substance as shell. The organic mineral composition according to the invention has multiple uses as fertilizer required by promoting plant growth and fodder required by promoting animal growth, and it is capable of being use as a seedling bowl or a covering material.
From the patent application description CN 104628427 A it is known manufacturing method of a humic acid activator for organic fertilizer production. The manufacturing method comprises the following steps: firstly, breaking macromolecule chemical bonds of a humic acid raw material through carrying out mechanochemical treatment on the humic acid raw material and an agent for breaking macromolecule chemical bonds of the humic acid raw material; secondly, performing acid washing; thirdly, performing alkali dissolving, and collecting filter liquor of sodium humate; and fourthly, performing acid precipitation. The fourth step concretely comprises: adding an inorganic acid into the sodium humate liquor resulting from the third step to adjust the pH of the liquor to 2.5 to create a brownish black fine precipitate; collecting the precipitate by filtration; washing the precipitate by adding distilled water; performing filtration; washing the precipitate again by adding water; performing filtering; and drying the precipitat at 50°C to obtain the humic acid activator. According to the invention, manufacturing steps are reduced; activity of humic acid is improved; and the manufacturing method has the advantages of operational simplicity, high production efficiency and low production cost.

The method involves preliminary preparation of an alkali solution, raw material - peat, sapropel, biohumus, brown coal - subjected to alkaline extraction and receipt dispersion and micronutrients are added. Before passage of alkaline extraction and cavitation dispersion, peat, sapropel and
biohumus are subjected to preliminary purification from sand and other insoluble inclusions, and brown coal - preliminary grinding to 0.5-1 mm fraction. 50% alkaline solution of KOH is introduced differentially until the active formation of humic and fulvic acid salts is stopped. Suspension of ready organomineral complex fertilizers undergoes multistage purification to produce ballast-free fertilizer. Method allows to produce ballast organic -mineral complex fertilizers due to use of multi-stage system for purification of suspension of finished product, as well as to improve quality of obtained fertilizers.

The encapsulated organic and mineral fertilizer, with an extended action, in granular form, manufactured using the method according to the invention, aims to decrease the negative impact of chemical compounds on the soil and increase of usage of minerals contained in it through the slower decomposition of mineral fertilizer granules in the soil. Encapsulation of the mineral fertilizer using organic matter and/or necessary components mixed with it, allows an introduction into the soil and plants components, which are necessary for their healthy development and a prevention of the soil degradation through introduction of the organic compounds and even a 3 -fold slower decomposition of minerals in the feitilizer granule. Elongation of the mineral fertilizer decomposition causes availability of nutrients for plants for an entire vegetation period. The chemical compounds contained in fertilizers are also leached into groundwater to a much smaller amount, reducing their contamination. The encapsulated organic and mineral fertilizer, with an extended action, in granular form, introduce into the soil the permanent humus in the form of the humic acids and mineral nutrients. Thereby, this fertilizer protects from the loss of the permanent humus and disappearance of biological life. Moreover, the fertilizer fulfills the possibility of mass production from commonly available raw materials, improving the crops economy.
