Combined use of green fertilizer and soil conditioner improves soil physicochemical properties, microbial community structure and tobacco quality in continuous cropping
Abstract Background Continuous tobacco cultivation over an extended period of time has decreased tobacco production quality, disturbed soil microbial populations and disrupted the soil structure. Therefore, measures to mitigate these ongoing cropping problems must be implemented. Objective To improv...

| description | Abstract Background Continuous tobacco cultivation over an extended period of time has decreased tobacco production quality, disturbed soil microbial populations and disrupted the soil structure. Therefore, measures to mitigate these ongoing cropping problems must be implemented. Objective To improve the soil quality caused by continuous cultivation of tobacco, so as to promote the growth of tobacco and improve the yield and quality of tobacco, which is of great significance to promote the sustainable development of agriculture. Methods We investigated the effects of green fertilizers and soil conditioners on the physicochemical characteristics, microbial diversity and chemical composition of flue-cured tobacco in continuous cropping soil. Result (1) When green fertilizers and soil amendments were applied, the bulk density of continuous cropping soil decreased, its porosity increased, and its fraction of macroaggregates in it increased. (2) The amount of available nitrogen (AN) and available phosphorus (AP) in the soil used for continuous cropping increased with the application of green fertilizers and soil additives. (3) The application of green fertilizers and soil additives altered the rhizosphere soil microbial composition and enhanced the diversity of the microbial community. (4) The alteration of rhizosphere soil physical and chemical properties indirectly affected the chemical composition and coordination of flue-cured tobacco. Conclusion The chemical composition and coordination of flue-cured tobacco might be affected by the physicochemical characteristics of the soil used for continuous cropping tobacco and the composition and community diversity of rhizosphere soil microorganisms. Furthermore, the most notable improvement in the soil for continuous cropping was attained by applying a combination of soil conditioner and green fertilizer. |
