Abstract:	This data package contains data on measured concentrations of nutrients in mesquite tree tissues collected from four habitat types at the Jornada Basin LTER site. These habitat types include: (1)playa, (2)arroyo,(3)dunes, and (4)grassland and samples were collected in conjunction with phenology studies and natural abundance of N15 sampling during 1987. Leaves, stems, flowers, and pods were collected from mesquite sample tissues and individually digested and analyzed for total nitrogen (Kjeldahl) and total phosphorus. This data set consists of the date of collection, collection site, leaf total nitrogen, stem total nitrogen, flower total nitrogen, pod total nitrogen, leaf total phosphorus, stem total phosphorus, flower total phosphorus, and pod total phosphorus. Data from this study was collected in 1987. Prior data was collected in 1986, but had differing attributes and is therefore published in a separate data package (knb-lter-jrn.210386008).

Description:

Sampling design and laboratory analysis

This study was conducted in 1987 as part of the Jornada Basin LTER program. The objective of this study was to measure plant tissue nutrients at mesquite (Prosopis glandulosa) dune sites of different habitat types. Mesquite tissues (leaf, stem, flowers, pods) were collected in conjunction with phenology studies and natural abundance of N15 during 1986 and 1987. This data package has only 1987 data; 1986 data are in EDI package knb-lter-jrn.210386008.

Four habitat types were sampled: (1) playa, within a dense stand of large (3-5 m tall) mesquite growing along the edge of of a large playa; (2) arroyo, with widely spaced mesquite trees (3-5 m tall) along the margin of temporary water courses; (3) dunes, which are dominated by low-growing coppice mesquite, and (4) grassland, at the base of a watershed with widely scattered mesquite, 2-3 m tall, many of the plants being multiple-stemmed. The dune site is located on theJornada Experimental Range (JER), while the other three sites are located on the NMSU Chihuahuah Desert Rangeland Research Center (CDRRC).

Mesquite tissue samples were digested and analyzed for total nitrogen (Kjeldahl) and total phosphorous. Plant tissue was oven-dried at 60 degrees C and ground to 20 mesh in a Wiley mill. One-tenth gram samples were weighed into 75ml Kjeldahl tubes and digested on a block digestor (40 tubes at a time). The digest was a micro- Kjeldahl sulfuric acid digest (Hg catalyst). An autoanalyzer was used to determine NH4 (TKN-Total Kjeldahl Nitrogen) and PO4-P (TP-Total Phosphorus). The method is described in Bremner et al. 1982.
