Introducing key microbes from high productive soil transforms native soil microbial community of low productive soil

This study aimed to understand the changes in rhizosphere microbial structure and diversity of native average yielding field site soil with the introduced microbial candidates from high yielding farms under greenhouse conditions. Outcome of the study indicated the potential to shift the microbial profile of average yielding sites by specifically introducing the potential key candidate from the high yielding sites to obtain sustainable biological soil health. To our knowledge, this is the first study describes the significance of the use of key individual microbes for community shift to transform low productive soils. AbstractThis study aimed to understand the changes in rhizosphere microbial structure and diversity of an average corn yielding field site soil with the introduced microbial candidates from a high ‐yielding site. Soils used in this study were from two growers’ fields located in Dunnville, Ontario, Canada, where one of the farms has an exceptional high corn yield (G‐site soil;ca 20  tons/acre) and the other yields an average crop (H‐site soil; 12 tons/acre) (8 years of unpublished A& L data). In growth room experiments using wheat as the indicator crop, calcium alginate beads with microbes composed ofAzospirillum lipoferum,Rhizobium leguminosarum,Burkholderia ambifaria,Burkholderia graminis,Burkholderia vietnamiensis,Pseudomonas lurida,Exiguobacterium acetylicum,Kosakonia cowanii, andPaenibacillus polymyxa was introduced into the soil at planting to the...
