Effects of microarthropod exclusion and water amendments on fluffgrass growth at the Jornada Basin LTER, March to September 1986

This data package contains fluff grass (Dasyochloa pulchella) growth
measurements taken during the growing period in 1986 (March, July, and
September). 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. 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. Within each plot, fluff
grass plants were permanently tagged for continuous measurements of
plant diameter and height during the three sampling dates. Data
consists of the date of measurement, the longest diameter (cm), the
diameter (cm) perpendicular to the longest diameter, and height (cm).
This study was completed in September 1986.
