Вопросы воспроизводства плодородия светло-серых лесных почв лесостепной зоны и утилизации отходов птицеводческой промышленности в качестве органических удобрений взаимосвязаны и являются весьма актуальными.Методы. В опытах изучалось действие одноразового внесения в почву различных доз (15, 30, 50 т/га) куриного помета, компоста из куриного помета и местных органических удобрений (сапропеля и торфа) на урожайность сельскохозяйственных культур и последействие удобрений на основные показатели почвенного плодородия — содержание гумуса, нитратного азота, фосфора и калия. Варианты опытов исследовались в шестикратной повторности. К лабораторным анализам почв и продукции растениеводства привлечен федеральный государственный центр агрохимической службы «Чувашский». Мeтоды анализов почвенных проб и продукции растениеводства — общепринятые в агрохимической науке.Результаты. Органические удобрения за три года исследований вносились в почву только один раз в начале опыта в дозах 15, 30 и 50 т/га, и действие их на урожайность и качество продукции растениеводства (клубни картофеля, зерна яровой пшеницы и гороха) в 2020–2022 гг. было положительным. Агрохимические свойства пахотного слоя почвы в вариантах с использованием органических удобрений значительно улучшились. Содержание нитратов в продукции в вариантах с дозами куриного помета и компоста 50 т/га и более приближались к критическому уровню. Местные удобрения (сапропель и торф) в дозе внесения в почву 30 т/га, куриный помет и компост в дозе внесения в почву 15 т/га являются хорошими органическими удобрениями, обладающими длительным последействием.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. The issues of reproduction of fertility of light gray forest soils of the forest-steppe zone and utilization of poultry industry waste as organic fertilizers are interrelated and are very relevant. Methods. The experiments studied the effect of one-time application of various doses (15, 30, 50 t/ha) of chicken manure, chicken manure compost and local organic fertilizers (sapropel and peat) on crop yields, and the aftereffect of fertilizers on the main indicators of soil fertility — amount of humus, nitrate nitrogen, phosphorus and potassium. The variants of the experiments were investigated sixfold. The Federal State Center of Agrochemical Service "Chuvashsky" was involved in laboratory analyses of soils and crop production. Mеthods of analysis of soil samples and crop production are generally accepted in agrochemical science.Results. Organic fertilizers for three years of research were introduced into the soil only once at the beginning of the experiment in doses of 15, 30 and 50 t/ha, and their effect on the yield and quality of crop production (potato tubers, spring wheat grains and peas) in 2020–2022 was positive. The agrochemical properties of the arable soil layer in the variants with the use of organic fertilizers have significantly improved. The nitrate content in the products in variants with doses of chicken manure and compost of 50 t/ha or more approached the critical level. Local fertilizers (sapropel and peat) at a dose of 30 t/ha, chicken manure and compost at a dose of 15 t/ha are good organic fertilizers with a long aftereffect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гумус</kwd><kwd>картофель</kwd><kwd>компост</kwd><kwd>сапропель</kwd><kwd>севооборот</kwd><kwd>плодородие</kwd><kwd>последействие</kwd><kwd>урожайность</kwd><kwd>горох</kwd></kwd-group><kwd-group xml:lang="en"><kwd>humus</kwd><kwd>potatoes</kwd><kwd>compost</kwd><kwd>sapropel</kwd><kwd>crop rotation</kwd><kwd>fertility</kwd><kwd>aftereffect</kwd><kwd>yield</kwd><kwd>peas</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Васильев О.А., Васильев А.О., Нурсов И.Н. и др.
