| The analysis of ecological danger from uncontrolled development of cyanobacteria which causes eutrophication of reservoirs was carried out. It was established that the use of cyanobacteria biomass after anaerobic fermentation as a fertilizer or component to create a growth substrate is promising. The research results showed the safety of these types of waste in terms of elemental composition (absence of limiting hazardous components that would adversely affect the growth and development of plants) and the presence of a significant amount of nutrients. The spent substrate contains calcium and sulfur (microelements necessary for balanced plant nutrition), the introduction of which in the fertilizer is appropriate, in greater amounts than other elements. The content of phosphorus and potassium (the main nutrients of plant nutrients) is at the level of the best varieties of mineral fertilizers. The analysis of the biomass of cyanobacteria before and after anaerobic fermentation showed that the biomass contains a significant part of nitrogen compounds, and their concentration after fermentation increases. The content of organic compounds decreases after fermentation, but is quite high as for organic-mineral fertilizers. The presence of fulvic and humic acids in the processed biomass, which are components for the reproduction of soil fertility and are also used in agriculture as plant growth stimulants, was determined. The practical possibility and economic feasibility of using the organic mass of cyanobacteria for the industrial production of biogas with the subsequent use of spent substrate as a balanced organic-mineral fertilizer in forestry and agriculture was proven. |
