Цель исследований заключалась в изучении различных способов основной обработки почвы и возможности применения илового осадка бытовых сточных вод, направленное на сохранение почвенного плодородия и повышение урожайности культуры.</p></sec><sec><title>Материал и методика</title><p>Материал и методика. Объектом исследований был сорт сафлора Александрит. Варианты опыта закладывали в 4-кратной повторности. Закладка опыта, проведение наблюдений и учетов выполнялись в соответствии с методикой полевых опытов Б.А. Доспехова.</p></sec><sec><title>Результаты</title><p>Результаты. В засушливых условиях Волгоградской области на светлокаштановых солонцеватых почвах проведены полевые исследования по изучению различных способов основной обработки почвы и возможности использования в качестве удобрения илового осадка сточных бытовых вод. Проведена оценка аминокислотного состава семян сафлора, представлены данные по изучению микробиологической активности почвы и влиянию нетрадиционных удобрений на увеличение активности почвенной биоты. Определена урожайность сафлора красильного в зависимости от изучаемых факторов и дана экономическая оценка возделывания данной культуры.</p></sec><sec><title>Заключение</title><p>Заключение. Для поддержания плодородия слабогумусированных почв в зоне засушливого климата, повышения уровня содержания аминокислот в растениях, увеличения биологической активности почвы, а также урожайности сафлора красильного требуются современные ресурсосберегающие технологии обработки почвы и нетрадиционные удобрения. Основа предложенных технических решений, базирующаяся на использовании в качестве основной обработки почвы чизельного рабочего органа Ранчо и внесении нетрадиционных удобрений-мелиорантов, обеспечивает восстановление структуры почвенных агрегатов, интенсификацию процесса гумусообразования, повышение микробиологической активности почвы, и как следствие, увеличение урожайности возделываемой культуры.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim.

The object of research was a safflower variety called Alexandrite. Experimental variants were carried out according to a 4-fold repetition. Experiment installation, observations and accounting were carried out in accordance with the field experiment methodology named after B.A. Dospehov.</p></sec><sec><title>Results</title><p>Results. Field research was undertaken in order to study the various methods of a basic tillage and a domestic wastewater silt sludge application possibility under arid conditions of the Volgograd region on light chestnut solonetz soils. The amino acid composition of safflower (Carthamus tinctorius) seeds has been estimated. The data from the study of soil microbiological activity and the effect of non-traditional fertilizers on the increase in the activity of soil biota are presented. The crop yields and economic evaluation of the Carthamus tinctorius cultivation were determined.</p></sec><sec><title>Conclusion</title><p>Conclusion. Modern resource-saving soil cultivation technologies and nontraditional fertilizers are required to: maintain the fertility of slightly humus soils in this arid climate zone, increase amino acids levels in plants, increase soil biological activity, as well to increase safflower crop yields. The proposed technical solutions, employing Rancho chisel tillage with as the basic tillage together with the introduction of non-traditional fertilizers-meliorants, provides structural restoration of soil aggregates, intensification of the humus formation process, increase in soil microbiological activity and - as a result - an increase in the yield of the cultivated Carthamus tinctorius crop.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Сафлор</kwd><kwd>урожайность</kwd><kwd>иловый осадок</kwd><kwd>основная обработка почвы</kwd><kwd>микробиологическая активность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Safflower</kwd><kwd>crop yields</kwd><kwd>silt sludge</kwd><kwd>basic tillage</kwd><kwd>microbiological activity</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">Балакшина В.И., Кулешов А.М.
