Abstract:

Soil nutrient distribution in NPP quads in the Mesquite, Grassland, Playa, Creosotebush, and Tarbush plant communities sampled at 3 spatial scales of grids. Soils were sampled from the NPP (biomass plots). Each of the five vegetation types (mesquite, grassland, playa, creosote, tarbush) had three sites (with low, medium, and high production levels). At 14 of 15 sites a grid of 70 by 70 meters was set out. Within this 49 plots of 10 by 10 meters were placed and labeled (numbered) in serpentine design. At the 15th site, Playa College, 48 plots of 10 by 10 meters were laid out in three long rows of 16 plots per row. At all sites the soil sample of 0-10 cm depth was taken 1 meter from the NE marker bar at a diagonal (heading toward the SW marker). At one of each of the five vegetation types another set of 49 soils (#101-149) was taken from within one of the 10 by 10 meter plots. Using a 7 by 7 meter grid (bounded by the southern east-west boundary line and the western north-south boundary line[#149 is in the SW corner]) soils were sampled 1 meter apart using a serpentine design.

This is part of a multi-part data set.

Data Use and Acknowledgement StatementThis dataset is released to the public and may be used for academic, educational, or commercial purposes subject to the following:ObjectivesThe Jornada Basin LTER Information Management System provides protocol and services for data collection, verification, organization, archives, and distribution.Quality Assurance StatementData managers interact with researchers during the entire scientific process--from the initial planning of sampling designs and field data collection to archiving and distribution of long-term data. The goal of data management is to build and maintain an archive of Jornada Basin LTER data files that are fully documented, error free, and organized in useful ways. Our protocol for data collection and processing seeks maximum interaction between researchers and data management personnel to avoid confusion and potential loss of data or problems with integrity of data. The data manager helps researchers to construct data forms that allow convenient data entry and analysis. Data documentation forms are completed by principal investigators prior to data entry. Data are entered into computer data files by data entry personnel using programs that error- check and verify the data as it is entered. Computer files are subjected to further verification by graphing and/or error-checking programs, and/or examination by field investigators. Error-checked data files are stored with associated documentation files on floppy disks and on a hard-disk database. Back-up data files are maintained as "hard-copy," on multiple floppy disks, and on read/write 30- year magneto-optical disks. Various sets of these data are stored at different sites on the NMSU campus. The final responsibility for quality assurance (both in data and documentation content) rests with the principal investigator who submits the data for inclusion in the Jornada Basin LTER Information Management System. To facilitate quality assurance, the data management staff will provide copies of data and documentation submitted by a principal investigator to that investigator upon request.Policy on Submission of DataAll data collected during a calendar year should be submitted to the Jornada Basin LTER data manager prior to July first of the following year. Data must be submitted with standard Jornada Basin LTER forms (both Project Abstract and Data Set documentation) which include objectives of the study, methods, as well as format and content of the data.Data Access PolicyData will be made publicly available no later than 2 years after submission of the data unless an earlier date is specified by the principal investigator. In the event that an extension of the 2 year period is necessary, the principal investigator may petition the Jornada Basin LTER Executive Committee for a longer protected period.Data Acknowledgement PolicyIndividuals and institutions utilizing data from the Jornada Basin LTER database are requested to place the following acknowledgment in any publication in which these data are mentioned: Data sets were provided by the Jornada Basin Long-Term Ecological Research (LTER) projects. Funding for these data was provided by the U.S. National Science Foundation (Grants DEB-92-40261 and DEB 94-11971). Please send 1 copy of any publication that cites Jornada Basin LTER data to: John P. Anderson Jornada Experimental Range P.O.

----------------------------------------------------------------Sampling:Soils were sampled from the NPP or biomass plots. Each of thefive vegetation types (mesquite, grassland, playa, creosote,tarbush) had three sites (with low, medium, and high productionlevels). At 14 of 15 sites a grid of 70 by 70 meters was set out.Within this 49 plots of 10 by 10 meters were placed and labeled(numbered) in serpentine design. At the 15th site, Playa College,48 plots of 10 by 10 meters were laid out in three long rows of 16plots per row. (It could have been 4 long rows of 12 plots perrow-- check with John Anderson). At all sites the soil sample of0-10 cm depth was taken 1 meter from the NE marker bar at a diagonal(heading toward the SW marker).At one of each of the five vegetation types another set of 49soils (#101-149) was taken from within one of the 10 by 10 meterplots. Using a 7 by 7 meter grid (bounded by the southern east-wetboundary line and the western north-south boundary line[#149 is inthe SW corner]) soils were sampled 1 meter apart using a serpentinedesign.Nutrient Analysis:Soils were kept in plastic bags and stored in a partly cooledhousetrailer in New Mexico over a two week period.%H2O--Gravimetric waterIn San Diego, soil subsamples were taken from the plastic bags,placed in soil cans and dried at 105�C for two days.Saturation %Soils were air dried and seived to 2mm. One hundred grams ofsoil was weighed into a disposable drinking cup. Using a 250 mlburet, water was added. The soil was stirred to take up the water,which was added until saturation was attained. The amount of waterrequired was recorded. Saturation %= (mls water/ wt of soil) X 100.One * or two * * in column next to sat% indicates sample was alittle too wet and too wet, respectively. It may be necessary tosubtract 0.5 ml and 1.0 ml from the amount of water. See referencesfor discription of what saturation looks/is like in different soils.References:Rhoades, J.D., 1982.

Amercury-potassium sulfate catalyst was used. The digest went fortwo hours after clearing at 375�C. Digests were analyzedcolorimetrically on a Technicon autoanalyzer.References:Total N by Kjeldahl digestion block techniques.(Bremnerand Mulvaney, 1982) Bremner, J.M., and C.S.
