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: 

Mesquite tissues (leaf, stem, flowers, pods) were collected in conjunction with phenology studies and natural abundance of N15 during 1986 and 1987. These were digested and analyzed for total Kjeldahl nitrogen and total phosphorous.

Abstract: 

This dataset quantities dissolved nutrients in water surface runoff from natural rainfall events at experimental hydrology plots on the New Mexico State University Ranch and USDA Jornada Experimental

This dataset quantities dissolved nutrients in water surface runoff from natural rainfall events at experimental hydrology plots on the New Mexico State University Ranch and USDA Jornada Experimental Range. Chemical analyses include F, Cl, NO3, SO4 by ion chromatography, NH4 by autoanalyzer, Ca, Mg, Na, K by atomic absorption spectrophotometry, and total N and P by auto- analyzer.  Nutrient losses from shrubland plots were greater than from grassland plots. The greater nutrient losses in shrublands were due to higher runoff, rather than higher nutrient concentrations in runoff. This study is complete. Refer to:

Abstract: 

Soil samples collected 5/12 and 5/13/86 to survey N availability in a variety of grassland and mesquite habitats. Objective is development of hypotheses about desertification processes that degrade grassland into mesquite dominated ecosystems. Measurements made of inorganic soil nitrogen.

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.

Abstract: 

An ion exchange resin bag technique (Binkley 1984, Lajtha 1988) was used to determine N availability in the rhizosphere of fluffgrass. Ion exchange resin bags were used to determine NH4. 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). Two CA-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.
