Установлено, что органические удобрения оказывали более выраженное положительное влияние на гумусовое состояние почвы, чем минеральная система удобрения. Наиболее выраженный эффект отмечен при внесении навоза под озимую пшеницу (с 1,67-1,70 до 1,74%). Заделка соломы оказывала более умеренное и не всегда статистически подтверждаемое влияние на содержание гумуса (с 1,68 до 1,70%). Применение минеральных удобрений не вызывало достоверных изменений этого показателя, по сравнению с контролем. Влияние удобрений, на групповой состав гумуса было выражено слабее, чем на общее содержание гумуса. Наиболее заметные изменения отмечены при внесении навоза, где отношение Сгк/Сфк снижалось до 0,72 против 0,74 на контроле. Показано, что в условиях богарного земле-делия навоз является наиболее эффективным фактором поддержания гумусового состояния почвы, а изменения, выявленные на начальном этапе применения удобрений, могут рассматриваться как индикаторы направленности последующей трансформации органического вещества при длительном применении органических материалов.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to assess the effect of manure, straw, and mineral fertilizers on the humus content and fractional composition of humus in light chestnut soil under a rainfed grain crop rotation in southeastern Kazakhstan. It was found that organic fertilizers had a more pronounced positive effect on the humus status of the soil than the mineral fertilizer system. The most distinct effect was observed after manure application under winter wheat, where humus content increased from 1.67–1.70% to 1.74%. Straw incorporation had a more moderate and not always statistically significant effect on humus content, increasing it from 1.68% to 1.70%. The application of mineral fertilizers did not cause significant changes in this indicator compared with the control. The effect of fertilizers on the fractional composition of humus was less pronounced than their effect on total humus content. The most noticeable changes were recorded under manure application, where the Cha/Cfa ratio decreased to 0.72 compared with 0.74 in the control. It was shown that under rainfed farming conditions, manure is the most effective factor for maintaining the humus status of the soil, while the changes identified at the initial stage of fertilizer application may be regarded as indicators of the direction of subsequent organic matter transformation under the long-term application of organic materials.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гумус</kwd><kwd>групповой состав гумуса</kwd><kwd>светло-каштановая почва</kwd><kwd>навоз</kwd><kwd>солома</kwd><kwd>богарное земледелие</kwd><kwd>зерновой севооборот</kwd></kwd-group><kwd-group xml:lang="en"><kwd>humus</kwd><kwd>fractional composition of humus</kwd><kwd>light chestnut soil</kwd><kwd>manure</kwd><kwd>straw</kwd><kwd>rainfed farming</kwd><kwd>grain crop rotation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данная статья опубликована в рамках программно-целевого финансирования научных исследований Министерства сельского хозяйства Республики Казахстан на 2024-2026 годы по программе ИРН BR22885097 «Обеспечение рационального использования земель сельскохозяйственного назначения в интенсивном земледелии на основе новых подходов в сохранении и воспроизводстве плодородия почв».</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">Докучаев В.В.
