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.
