AbstractRecent studies suggest that rhizosphere soil microarthropods may have a major role in determining soil nitrogen availability. Desert soil microarthropods are consumers of soil bacteria, fungi, and nematodes, thus they accelerate mineralization processes by causing turnover in immobilized nitrogen. Therefore, I hypothesized that changing densities of soil microarthropods would result in changes in nitrogen availability.... These data suggest that in the live rhizosphere of Erioneuron pulchellum, if water is available, then soil biota and nitrogen dynamics might be regulated by organic matter. Also, there were no significant differences in nitrogen mineralization potentials of soils from the various treatments. These data indicate that soil microarthropods are not essential for nitrogen mineralization or other aspects of the nitrogen cycle in the rhizosphere of fluff grass.
