Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains fluff grass (Erioneuron pulchellum) measurements taken during the growing period in 1986 (March, July, and September). The purpose of this study was to test if changing densities of soil microarthropods and nematodes results in changes in fluff grass growth. The experimental design consisted of 20 plots (each 6m x 6m) and 3-meter buffers between each plot. Four treatments were assigned to 5 plots each 1) Chlordane, 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 for 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 complete in September 1986.

Methods and protocols used in the collection of this data package

Description:

Twenty 6 x 6 m plots with a 3-meter buffer zone were established on the Jornada Basin in 1986. Five plots each were randomly assigned to one of four treatments: (1) chlordane amendment (100ml Al (Active Ingredients) per 10,000 ml) to exclude microarthropods, (2) water (irrigation 6 mm per week), (3) water (6 mm per week) plus chlordane amendment (100 ml Al per 10,000 ml) and (4) control, no treatment.

Fluff grass plants were permanently tagged in each of the 20 plots to be measured in March, July, and September. In March, 20 plants were measured in each plot; in July, 7 plots had 10 measurements and 13 plots had 20 measurements; in September, 7 plots had 10 plants and 13 plots had 16 plants measured. The data measurements in this package consist of the longest diameter (cm) on the plant (DIAM1), the diameter (cm) perpendicular to the longest diameter (DIAM2), and height of the plants (cm).
