Научные предпосылки разработки органоминеральных удобрений на основе сапропелей с учётом углеродно-азотного баланса, гумусового состава и микробиологической активности
Scientific basis for the development of sapropel-based organic-mineral fertilizers taking into account the carbon–nitrogen balance, humus composition and microbiological activity

Abstract
This paper presents the results of composting processes using sapropel from fish farms in the Syrdarya and Khorezm regions as a primary feedstock. The research examines the transformation of organic matter (OM) from these components into humic compounds with varying C/N ratios. It was found that increasing the ratio of sapropel to manure, combined with a maturation period of 1–150 days, led to a higher degree of humification and reduced loss of material to the gas phase. The optimal composting conditions were determined to be a sapropel-to-manure ratio of 70:30 and a maturation period of 90 days.
