Building upon this model, . we present a new conceptual framework arguing that along with depolymerization, mineral-organic associations may proximally regulate the provisioning of bioavailable organic N monomers especially in the rhizosphere. . 141 EN.

Soil microorganisms serve as biogeochemical agents for the conversion of complex organic compounds into simple inorganic compounds.. Foliar application of various chemicals leads to alterations in the rhizosphere micro flora by changing the pattern of root exudates. . The pattern of the rhizosphere microflora i.e. numbers and species composition can be changed by various factors, such as:. In the . rhizospheres. of maize, acorn squash, and pinto beans. Host-associated microbial communities. Eukaryotes play host to large and complex microbial communities. In humans, for instance, 90% of the cells are accounted for by the host-associated microbes.
