Abstract: 

Five mesquite dunes were irrigated by pumping water from a storage tank located 200 m away. Five nonirrigated dunes served as control. Soil samples were collected from mesquite trees at control and watered sites, and analyzed for the number of rhizobia nodules. This study is complete.

Abstract: 

Plant and soil samples were collected from mequite dunes sites which had not been irrigated (control)  or had been irrigated (treatment) with water. Soil samples were collected (hand augered) under mesquite (Prosopis glandulosa) trees  to three depths, 0-50 and 50-100, and 100-150cm. Soil samples were placed in plastic bags, tied, and stored in portable coolers. Soil samples were analyzed for zinc , cupper, iron, and manganese. Plant tissue was analyzed for total nitrogen and total phosphorous. This study has been completed.

Abstract: 

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 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). Soil total Nitrogen was determined in the rhizosphere of fluffgrass.

Measurements are taken on Erioneuron pulchellum at monthly intervals. Three randomly located subsamples are collected from each plot. Data set contains plant diameters, mites soil weight, root weight, nematode soil weight, root total nitrogen, and nematode number.

Abstract: 

This data set consists of periodic size measurements of permanently marked individual fluff grass plants. Measurements were taken in March, July, and September 1986. 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 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). Three randomly located subsamples were taken from each plot.

Abstract: 

Dry weight biomass and total nitrogen were determined for flowers, green leaves and yellow and grey leaves of fluffgrass plants collected from plots. 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 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).
