Development of a new algorithm for obtaining highly effective bio-fertilizer from mixtures of peat and bird droppings

Abstract

VNIIMZ has long and fruitfully been working on the creation of bio-fertilizers and multifunctional bio drugs produced by the method of directional bioconversion. This article reflects the innovative elements of a fundamentally new technology for producing promising bio-fertilizers. The development of a new bioconversion algorithm for peat and bird droppings mixtures was aimed at creating a competitive bio-fertilizer with favorable acidity, a high number of agronomically beneficial microflora, the presence of nutrients in a form available for plants and microflora, and was done by choosing the most effective bioconversion process. Compared 3 different process parameters, laid three times. Their assessment was carried out according to the content in the initial peat and bird droppings mixtures and in the final products (variants of the biological fertilizer) ammonifying and amylolytic microorganisms, sanitary indicative microflora (enterobacteria), fungi, actinomycetes, on the activity of oxidoreductases, on the level of agrochemical parameters. The algorithm for conducting the fermentation process includes acid hydrolysis of the initial mixture and two temperature stages. At the first stage, proceeding at 55-60С within 24 hours, the necessary ecological bio-fertilizer is achieved, characterized by a minimum of sanitary and representative microflora - enterobacteria and low content of spoilage microorganisms - fungal flora. At the second stage of bioconversion, occurring at a temperature of 36-39 С for 96 hours, the microflora actively develops, participating when using this fertilizer in the formation of soil structure, a high level of its effective fertility. During the development process, the choice was made of the option of conducting a fermentation process, which differs from the others by a higher content of agronomically beneficial microflora, a minimum of microorganisms of the genus Enterobacter and a high content of key nutrients (nitrogen, phosphorus, potassium) for plant growth.
