Title:Estimated Number of Nodulating Rhizobia in Mesquite at Watered and Unwatered Dune Sites in the Jornada Basin, 1988 and 1989
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This package contains data from a study that measured concentrations of mesquite-nodulating rhizobia nodules on irrigated and non-irrigated dune plots at the Jornada Experimental Range from 1988-1989. Five mesquite dunes were irrigated by pumping water from a storage tank located 200 m from the site to the apex of each dune. Irrigation began in March with approximately 2.5 cm applied 2-3 times/week for 6 weeks to initially wet the dry soil. Thereafter high water availability was maintained by weekly irrigation. Five non-irrigated dunes served as control. Five to 6 replicate soil samples were collected with hand augers under each mesquite shrub (Prosopis glandulosa) to three depths, 0-50 and 50-100, and 100-150cm. Concentrations of mesquite-nodulating rhizobia in field-moist soil samples were estimated using the plant-infection, most probable number (MPN) technique. Data consists of the date of collection, treatment, mesquite dune number, depth, replicate, and number of nodules. This study is complete.

Description:

Design, treatments, and vegetation measurements

This study was conducted on the Jornada Experimental Range (JER) from 1988-89. The objective of this study was to measure nodulating rhizobia of honey mesquite shrubs (Prosopis glandulosa) of irrigated treatments and non-irrigated controls. Precipitation is 230mm/yr, with half occurring during the summer. The vegetation is coppice mesquite dunes (30% cover) with scattered shrubs of saltbush and snakeweed. Five mesquite dunes were irrigated by pumping water from storage tank located 200 m from the site. Water was applied to the dunes with an overhead sprinkler (later replaced by a drip irrigation system to minimize wind drift) located at the apex of each dune. Irrigation began in March with approximately 2.5 cm applied 2-3 times/week for 6 weeks to initially wet the dry soil. Thereafter high water availability was maintained by weekly irrigation. Five non-irrigated dunes served as control. Soil samples were collected with hand augers under each mesquite to three depths, 0-50 and 50-100, and 100-150cm. Soil samples were placed in plastic bags, tied, and stored in portable coolers. Concentrations of mesquite-nodulating rhizobia in field-moist soil samples were estimated using the plant-infection, most probable number (MPN) technique (Vincent 1970).
