  • This data package contains data on nitrogen (as ammonium, NH4+) availability, measured with ion exchange resin bags, in fluffgrass ( Dasyochloa pulchella ) rhizosphere soil from 1986-1987. The purpose of this study was to test how watering, and changing densities of soil microarthropods and nematodes, results in changes in fluff grass growth. An ion exchange resin bag technique (Binkley 1984, Lajtha 1988) was used to determine ammonium availability. Twenty 6 x 6 m plots were established with a 3 m buffer between plots. Five plots were randomly assigned to one of four treatments:1) Chlordane (to exclude microarthropods), 2) Chlordane and water, 3) Water, and 4) Control. Two cation exchange bags were placed in the rhizosphere of a fluffgrass plant in each plot. Bags were left in the field 3 months, collected, brought to the lab and analyzed for available ammonium (NH4+) using a salicylate procedure. The data table contains bag collection date, treatment, and NH4+ (mg/kg) concentration. This study is complete.
