Анализ качественных характеристик органических удобрений, полученных из отходов птицефермы предприятия srl "Piliccik-Grup"

Abstract

The paper presents the results of a chemical analysis of the parameters of the bird droppings and products obtained from it: compost and biohumus. It is shown that under the conditions of the enterprise LLC "Piliccik-Grup" the mixture of droppings with straw bedding formed as waste can serve as a source for the production of environmentally friendly organic fertilizer. In the studied mass, the content of heavy metals, persistent organic pollutants (pesticides), and drugs was not detected or their value is significantly lower than the maximum allowable concentrations. It was also shown that compost and biohumus obtained under the technological conditions of the enterprise contain high concentrations of macro- and microelements and can be used as fertilizers.
