Title:Nutrient analyses of Mesquite tissue in the Jornada Basin, 1987
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data package contains data on measured concentrations of nutrients within various plants’ tissues in four habitat types of the Jornada Experimental Range and New Mexico State University College Ranch. These habitat types include: (1)playa, (2)arroyo,(3)dunes, and (4)grassland. 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, pod total nitrogen, flower total nitrogen, composite pod total nitrogen, composite flower total nitrogen, flower and pod total nitrogen, leaf total phosphorus, pod total phosphorus, flower total phosphorus, composite pod total phosphorus, composite flower total phosphorus, and flower and pod total phosphorus. Data from this study was collected in 1987. Additional data was previously collected in 1986, but had differing attributes and is therefore published in a separate data package (210386009).

Description:

Design, treatments, and vegetation measurements

This study was conducted on the Jornada Experimental Range (JER) in 1987. The objective of this study was to measure plant tissue nutrients at mesquite (Prosopis glandulosa) dune sites of different habitat types. Four habitat types were sampled: (1) playa, within a dense stand

of large (3-5 m tall) mesquite growing along the edge 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 the USDA Jornada Experimental Range, while the other three sites arelocated on the New Mexico State University College Ranch. Mesquite tissues (leaf, stem, flowers, pods) were collected in

conjunction with phenology studies and natural abundance of N15 during 1986 and 1987. These were digested and analyzed for total nitrogen (Kjeldahl) and total phosphorous. Plant tissue was oven-dried at 60o 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).
