资源简介：
This data package contains data on soil nitrogen mineralization
potential in a variety of grass and mesquite habitats during the early
years of the Jornada Basin LTER project (I-II). Soil cores were
collected from Jornada Experimental Range and Chihuahuan Desert
Rangeland Research Center (CDRRC) lands in May 1986, and observed in a
leaching incubation study. The purpose of this study was to measure
inorganic soil nitrogen in the context of the shift from grasslands to
mesquite dominated ecosystems. Sites include fluff grass (Dasyochloa
pulchella), black grama (Bouteloua eriopoda), Sporobolus/Gutierrezia,
playa mesquite (Prosopsis glandulosa), and arroyo mesquite ecosystem
types. Soil samples were collected on May 12-13, 1986 within the
clumps of grass or beneath mesquite at each site, generally 20 cm deep
or to the hard pan (whichever came first). During the incubation
study, inorganic nitrogen leaching was measured for 28 weeks for each
sample. This study is complete.
