Hydrology natural runoff plots - runoff

NAL Geospatial Catalog

    OVERVIEW This is the Jornada Long Term Ecological Research site data base for the 2 x 2 meter natural rainfall-runoff plots. There are 4074 plot-events or observations in the data set.

    Hydrology plot surface runoff water chemistry

    NAL Geospatial Catalog

      The data consists of chemical analyses of dissolved ions in samples of surface runoff from natural rainfall events collected from experimental hydrology plots in creosotebush scrub and grass- land areas of the New Mexico State University Ranch and

      Plant phenology transect at NPP sites

      NAL Geospatial Catalog

        The phenological stage of all perennial plant species on the 15 NPP sites is recorded on a monthly basis. This allows us to track the influence of weather and of site differences on plant reproduction.

        Fluffgrass cation exchange resin bags for NH4

        NAL Geospatial Catalog

          An ion exchange resin bag technique (Binkley 1984, Lajtha 1988) was used to determine N availability in the rhizosphere of fluffgrass. Ion exchange resin bags were used to determine NH4.

          Fluffgrass anion exchange resins bags for NO3

          NAL Geospatial Catalog

            An ion exchange resin bag technique (Binkley 1984, Lajtha 1988) was used to determine N availability in the rhizosphere of fluffgrass. Ion exchange resin bags were used to determine NO3.

            Fluff grass mesocosm: mites and nematodes

            NAL Geospatial Catalog

              A mesocosm experiment was conducted on fluff grass (Erioneuron pulchellum) plants to look at the effect of exclusion of mites (with chlordane), nematodes (NEMACUR), mites and nematodes, on soil available, total and microbial nitrogen.
