Abstract
Abstract. The roles of microorganisms in enhancing crop production
have been demonstrated for a range of cropping systems. Most studies to
date, however, have been confined to a limited number of locations, making
it difficult to identify general soil biotic and abiotic characteristics
underpinning the yield-promotion across various locations. This knowledge
gap limits our capacity to harness soil microbiome to improve crop
production. Here we used high-throughput amplicon sequencing to investigate
the common features of bacterial community composition, ecological networks
and physicochemical properties in six yield-invigorating and adjacent
yield-debilitating orchards. We found that yield-invigorating soils
exhibited higher contents of organic matter than yield-debilitating soils
and harbored unique bacterial communities. Greater alpha diversity and
higher relative abundances of Planctomycetota and Chloroflexota were
observed in yield-debilitating soils. Co-occurrence network analysis
revealed that yield-invigorating soils displayed a greater number of
functionally interrelated modules (meta-modules) and a higher proportion of
negative links to positive links. Chloroflexota was recognized as a keystone
taxon in manipulating the interaction of bacterial communities in
yield-invigorating soils. Altogether, we provide evidence that
yield-invigorating soils across a range of locations appear to share common
features, including accumulation of soil organic matter, higher microbial
diversity, enrichment of key taxa like Chloroflexota and maintaining a
competitive network. These findings have implications for science-based
guidance for sustainable food production.
期刊介绍:
Cessation.Soil Science satisfies the professional needs of all scientists and laboratory personnel involved in soil and plant research by publishing primary research reports and critical reviews of basic and applied soil science, especially as it relates to soil and plant studies and general environmental soil science.
Each month, Soil Science presents authoritative research articles from an impressive array of discipline: soil chemistry and biochemistry, physics, fertility and nutrition, soil genesis and morphology, soil microbiology and mineralogy. Of immediate relevance to soil scientists-both industrial and academic-this unique publication also has long-range value for agronomists and environmental scientists.
