Analysis of poultry manure utilisation methods to produce organic fertiliser
(Lviv Politechnic Publishing House, 2018-02-26) Malovanyy, Myroslav; Odnorih, Zoryana; Kanda, Mariya; Lviv Polytechnic National University
This article provides an overview of the poultry manure utilisation issues. It gives a comparative analysis of the methods of composting and vermiculation, production of organic-mineral fertilisers, granulation and thermal drying of the output raw product. Integrated combination of granulation and thermal drying is considered to be the most efficient in the poultry manure processing technology.
Determination of an impact of the composition on the pH level and the concentration of ammonium nitrogen in soil of Pustomyty distrаct, Lviv region
(Publishing House of Lviv Polytechnic National University, 2017) Кanda, Maria; Malovanyy, Myroslav; Оdnorih, Zoryana; Lviv Polytechnic National University
This research involves studying the application of palygorskite from Dashukivka Deposit and clinoptilolite from Sokyrnytsia Deposit in production of organic fertilizers prolonged. It is found that maximum ammonia sorption capacity is 1.56×10-2 mg-eq/g of sorbents. The composition proposed has a positive impact on condition of the studied soils. The pH level of soil solution shifts toward neutral, and the level of ammonium nitrogen is uniform throughout 24 days.
