Breaking continuous potato cropping with legumes improves soil microbial communities, enzyme activities and tuber yield
This study was conducted to explore the changes in soil microbial populations, enzyme activity, and tuber yield under the rotation sequences of Potato-Common vetch (P-C), Potato-Black medic (P-B) and Potato-Longdong alfalfa (P-L) in a semi-arid area of China. The study also determined the effects of continuous potato cropping (without legumes) on the above mentioned soil properties and yield. T...
متن کاملEffects of different 3-year cropping systems on soil microbial communities and rhizoctonia diseases of potato.
ABSTRACT Eight different 3-year cropping systems, consisting of soybean-canola, soybean-barley, sweet corn-canola, sweet corn-soybean, green bean-sweet corn, canola-sweet corn, barley-clover, and continuous potato (non-rotation control) followed by potato as the third crop in all systems, were established in replicated field plots with two rotation entry points in Presque Isle, ME, in 1998. Cro...
متن کاملFluctuations of soil bacterial communities under potato cropping
It is important to understand the underlying factors that lead to shifts in soil microbial communities, not simply for the characterization of these complex biotic systems, but also to understand the impact that changes in microbial community composition may have on terrestrial ecosystems. In this study, the impact of genetically different potato (Solanum tuberosum) plants growing in arable soi...
متن کاملImpact of Environmental Stress-Tolerant Transgenic Potato on Genotypic Diversity of Microbial Communities and Soil Enzyme Activities under Stress Conditions.
Transgenic crops able to tolerate environmental stress are being developed throughout the world. However, little data is available on the impact of environmental stress-tolerant transgenic crops on soil microorganisms and biochemistry. Recently developed transgenic potato plants carrying an environmental stress-related gene, DREB1A, with a stress-inducible promoter, are being evaluated for grow...
متن کاملResponse of enzyme activities and microbial communities to soil amendment with sugar alcohols
Changes in microbial community structure are widely known to occur after soil amendment with low-molecular-weight organic compounds; however, there is little information on concurrent changes in soil microbial functional diversity and enzyme activities, especially following sorbitol and mannitol amendment. Soil microbial functional diversity and enzyme activities can be impacted by sorbitol and...
