16S_Soil_Globaldata_Ricepaddy, Soil microbiome interacts with geochemistry to regulate paddy arsenic and cadmium availability and arsenic transformation
16S_Soil_Globaldata_Ricepaddy, Grain mineral nutrition will be determined by the concentrations of elements naturally or artificially introduced into soils, and how their availability is altered by a complex interaction of abiotic processes (mineral form and location, redox), biotic processes (i.e. driven for example by soil bacteria, fungi) and crop management practices. Here we studied the primary factors in driving grain mineral nutrition by investigating >130 soils from widely varying geographic location and paddy management practices, encompassing East Africa, Sri Lanka, Vietnam through to Spain and France. Matched soil, straw and grain were collected at harvest. Field fresh soil was transported to the laboratory and incubated under flooded conditions and soil porewater chemistry and soil microbiome investigated alongside soil, straw and grain chemistry.
