Assessing the Amount of Chemical Elements in Biodegradable Agricultural Wastes and ASH Chemini element kiekio bioskaid iose em s ūkio atliekose ir j pelenuose vertinimas

Biodegradable agricultural wastes such as manure, has long been used as an organic fertilizer that improves soil structure, enriches the soil with micro-organisms and micro-elements necessary for plants and promotes humus formation. Manure can also be successfully used as a renewable energy source directly combusting and extracting energy. The carried out investigation showed that the incineration of manure remaining in ashes could also be used as a fertilizer. Waste combustion reduces its volume to 80–90%. Also, the investigation revealed that the amount of chemical elements (Na, Mg, Si, P, K, Ca, Ti, Mn, Fe) decreased after combustion. However, the concentration of these elements in ashes is higher than that in raw manure. Article in Lithuanian Bioskaid ios em s ūkio atliekos – m las, srutos, kraikas – nuo seno naudojamos kaip organin tr a, gerinanti dirvos struktūr , praturtinanti dirvo em mikroorganizmais, reikiamais augalams mikroelementais, skatinanti susidaryti humus . M las, termi kai apdorotas tiesiogiai deginant ir i gaunant energij , taip pat gali būti s kmingai naudojamas kaip atsinaujinantis energijos altinis. Tyrimais nustatyta, kad sudeginus m l lik pelenai irgi gali būti naudojami tr ti. Degimo metu atliek tūris suma ja apie 80–90 % – sudega did ioji dalis organini med iag . Taip pat tyrimais nustatyta, kad m le esan i chemini element (Na, Mg, Si, P, K, Ca, Ti, Mn, Fe) kiekis po degimo suma ja, ta iau pelenuose i element yra didesn s koncentracijos nei vie iame m le.
