The aim of this study was to test the hypothesis that intercropping (common bean - maize) in P deficient soil, can enrich carbon (C) and nitrogen (N) of the microbial biomass (MB) through a transfer from root nodules of the plant and rhizospheric microbial flora in a field located in “Setif region” in northern Algerian agroecosystem(Mediterranean climate). The rate of nodular N sequestered in intercropped common bean was higher compared to sole crops and fallow. However, under intercropped and low P conditions, the rate of nodular N sequestered is highest over two years. Carbon of the microbial biomass (MB-C) is higher in the intercropping compared to sole crops and fallow but it is even higher in P deficient soil. Moreover, a strong correlation is established between nodular C and MB in intercropping under low P conditions. In these same conditions, the total soil respiration was the highest and the lowest C:N ratio of MB was recorded. These results showed that in low P soil, intercropping is a good solution to enhance the rhizospheric MB that can fertilize the soil and recycle mineral elements.</abstract><trans-abstract xml:lang="ru"><p>В предыдущих работах уже сообщалось о положительном влиянии смешанных посевов в условиях низкого содержания фосфора (Р). Цель данного исследования заключалась в проверке информации о том, что смешанные посевы (фасоль обыкновенная - кукуруза) на почвах с низким содержанием Р могут увеличить долю углерода (C) и азота (N) микробной биомассы (МБ) путем их перемещения из корневых клубеньковых растений и ризосферной микрофлоры на поле, расположенном в регионе Setif на севере Алжира (средиземноморский климат). Количество N, сосредоточенного в клубеньках фасоли обыкновенной, было выше при выращивании в поликультуре по сравнению с монокультурой и паром. Тем не менее, несмотря на низкое содержание P в почве, при смешанном выращивании уровень N в клубеньках оказался самым высоким за два года. Содержание С в микробной биомассе (МБ-С) было выше при поликультуре по сравнению с монокультурой и паром, однако этот показатель увеличивался в почвах с дефицитом Р. Кроме того, установлена сильная корреляция между клубеньковым С и МБ при поликультуре в условиях низкого Р обеспечения. В тех же условиях показатель общего «дыхания почвы» имел самое высокое значение и отмечалось самое низкое соотношение C: N МБ. Полученные результаты свидетельствуют о том, что при низком содержании P в почве смешанные посевы являются продуктивным способом увеличения ризосферной МБ, которая способна повысить плодородие почвы и рециркулировать минеральные элементы. Ключевые слова: Поликультура; низкое содержание Р; микробная биомасса; углерод; азот; Агроэкосистема.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Intercropping</kwd><kwd>P-Deficiency</kwd><kwd>Microbial biomass</kwd><kwd>Carbon</kwd><kwd>Nitrogen</kwd><kwd>agroecosystem</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>глубокая обработка почвы</kwd><kwd>антропогенное воздействие</kwd><kwd>технология стриптил</kwd><kwd>полосная обработка почвы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Cong WF, Hoffland E, Li L, Six J, Sun JH, Bao X G, Van Der Werf W.
