Abstract

Associated with a project that was based upon the assumption that nitrogen may limit net primary plant production in desert grasslands, this project began measuring available inorganic soil N and potentially mineralizable N of soils at two desert grassland locations. Both available N and potentially mineralizable N were greatest following a drought period in 1989, declined during wetter periods that followed and remained relatively stable until another extended drought period. After drought in 1995-6, both forms of soil N increased, indicating the potential for greater NPP following drought and lower potential NPP during periods of normal precipitation.

Spatial coverage

Bronco Well is located near the northern boundary of the Sevilleta NWR, approximately four miles west of the AT&T on the road to Red Tank.Five Points is the area which encompasses the Five Points Black Grama and Five Points Creosote Core study sites and falls along the transition between Chihuahuan Desert Scrub and Desert Grassland habitats. Both sites are subject to intensive research activity, including NPP measurement, phenology observation, pollinator diversity studies, and ground dwelling arthropod and rodent population assessments. There are drought rain-out shelters in both the Black Grama and Creosote sites, as well as the mixed-ecotone, with co-located ET Towers.
