The subject of the invention is fertilizer with controlled nutrition components release in relation to application of fertilization time and fertilizer with controlled components release production method. The fertilizer with controlled components release comprising shredded, dried and sterilised biomass containing protein from 1,0 to 30% w/w, phosphorus 0,5 to 15% w/w, potassium compound 2 to 25% w/w, sulphur compounds 0,5 to 3,0% w/w, reactive alkaline substances 5 to 40% w/w, and applied nutrient agent core layer constitute substances limiting duration of ability to rinse and microbiological decompose of soluble component in amount of 1 to 10% w/w. Method of fertilizer production with controlled components release charatcerise, with fact, that biomass with high content of protein, preferably 10 to 25% and/ or phosphorate compounds and/ or potassium compounds, and/ or sulphur compounds are ground and alkaline reagent is added in amount of 5 to 30% w/w, preferably 15 - 20%, next introduced components are subject to homogenisation and dank and homogeneous substance is subject to sterilisation and drying process, whereas during exothermal hydration at the same time is initiated process of alkaline hydrolysis of organic biomass components in temperature exceeding 60 0 C for at least 20 minutes, and then received substance is dried in temp. 60°C to 95 °C until it reaches 15% do 20% of humidity, and wherefore receive fertilizer is subject to granulation process and on produced fertilizer granules are applied substances restricting for some period of time ability to rinse out and microbiological decompose of fertilizer components. Sowed fertilizer is ploughed into the ground, on depth of 20 to 30 cm. |
