EDI Staging Environment
Recent 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. This study was part of a larger investigation in which nematodes, mites, litter, and plant material was also collected. Twenty 6 x 6 m plots were established in areas comprised of fluffgrass (Erioneuron pulchellum) with a 3 m buffer between plots. Five plots were randomly assigned to one of four treatments: (1) chlordane amendment 100ml AI (active ingredients) per 10,000 ml) to exclude microarthropods, (2) sprinkler irrigation (6 mm per week), (3) sprinkler irrigation (6 mm/week) plus chlordate amendment (as above), (4) control (no treatment). For this portion of the study, cation exchange bags were placed in the rhizosphere of a fluffgrass in each plot. Bags were left in the field 3 months, collected, brought to the lab and analyzed for NO3 -N using a cadmium reduction procedure.
For additional data from this larger study, refer to other JRN packages that are part of study 385, including 210385004, 210385002, 210385003, 210385008, 210385006, 210385001. Sampling occurred in 1987. This study is complete.
