Существующие методики для расчета объема выбросов климатически активных веществ основаны на укрупненных коэффициентах, без учета климатических зон и применяемых технологий переработки навоза. Цель исследования – определить концентрации климатически активных веществ в эмиссии в зависимости от систем переработки различных видов жидкого навоза. Исследования проводили на экспериментальной установке с возможностью имитации различных условий переработки твердого и жидкого навоза объемом 0,0625 м3. В качестве исследуемого материала использовали жидкий навоз крупного рогатого скота (КРС), жидкий свиной навоз, жидкая фракция навоза КРС и жидкая фракция свиного навоза. Измерение концентрации СО2, СН4, H2S, и NH3 осуществляли газоанализатором «ЭЛАН плюс». Концентрацию N2O определяли в газовом хроматографе «Кристаллюкс-4000М». Концентрация газов в жидком навозе КРС составила: CO2 – 537–539 мг/м3, CH4 – 0,02-0,03 %, H2S – 0,147–0,367 мг/м3, NH3 – 1,97–4,34 мг/м3, в жидкой фракции навоза КРС следующая: СО2 – 537–538 мг/м3, СН4 – 0,02 %, H2S – 0,367–0,327 мг/м3, NH3 – 2,53–4,08 мг/м3, в жидком свином навозе – СО2 – 537–718 мг/м3, СН4 – 0,02 %, H2S – 0,12–0,177 мг/м3, NH3 – 4,69–6,97 мг/м3, в жидкой фракции свиного навоза – СО2 – 537–592 мг/м3, СН4 – 0,01-0,02 %, H2S – 0,08–0,20 мг/м3, NH3 – 1,57–2,72 мг/м3. Полученные в результате исследования значения концентраций климатически активных веществ при переработке жидкого навоза КРС и жидкой фракции навоза КРС сопоставимы с результатами аналогичных исследований, отличия составляют менее 20 %.</p></abstract><trans-abstract xml:lang="en"><p>The amount of climate-active substances emissions depends on the technology and the mode of manure processing. Current methodologies for calculating these emissions are based on aggregated coefficients that do not consider climatic zones or the manure processing technologies in place. The aim of the study was to determine the concentration of climate-active substances in the emissions in dependence to the processing systems of different types of liquid manure. The research was carried out using the experimental unit with a volume of 0.0625 m3 that was designed to simulate the processing of solid and liquid manure under different conditions. As the research material there was used liquid cattle manure, pig liquid manure, and the liquid fractions of both cattle and pig manure. Concentrations of СО2, СН4, H2S, and NH3 were measured with an ELAN Plus gas analyzer. N2O concentration was determined in a gas chromatograph “Crystallux-4000M”. Concentration of СО2 in liquid cattle manure was found to be 537–539 mg/m3, СН4 – 0.02-0.03 %, H2S – 0.147–0.367 mg/m3, and NH3 – 1.97–4.34 mg/m3. Concentration of СО2 in liquid fraction of cattle manure was found to be 537–538 mg/m3, СН4 – 0.02 %, H2S – 0.367–0.327 mg/m3, and NH3 – 2.53–4.08 mg/m3. Concentration of СО2 in pig liquid manure was found to be 537–718 mg/m3, СН4 – 0.02 %, H2S – 0.12–0.177 mg/m3, and NH3 – 4.69–6.97 mg/m3. Concentration of СО2 in liquid fraction of pig manure was found to be 537–592 mg/m3, СН4 – 0.01-0.02 %, H2S – 0.08–0.20 mg/m3, and NH3 – 1.57–2.72 mg/m3. The obtained concentrations of climate-active substances in the emission from processing of liquid cattle manure and its liquid fraction were comparable with the results of similar studies. The differences were less than 20 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сельское хозяйство</kwd><kwd>животноводство</kwd><kwd>системы переработки навоза</kwd><kwd>концентрации газов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>agriculture</kwd><kwd>animal husbandry</kwd><kwd>manure processing systems</kwd><kwd>gas concentrations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при поддержке Минобрнауки РФ в рамках выполнения Государственного задания ФГБНУ «Федеральный научный агроинженерный центр ВИМ» (тема № FGUN-2025-0010).</funding-statement><funding-statement xml:lang="en">the research was supported by the Ministry of Science and Higher Education of the Russian Federation within the state assignment of the Federal Scientific Agroengineering Center VIM (theme No. FGUN-2025-0010).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Брюханов А.
