Abstract: 

This data set was collected to provide data for comparison of the losses of dissolved nitrogen and phosphorus in the runoff from grass- and shrub- dominated plots in the Jornada Basin of southern New Mexico. This summary dataset contains the following columns for the shrub plots: Plot: the identification number for the 6 grassland plots.

Q: the mean rate of discharge during the entire experiment, obtained by dividing the total runoff by l800 sec. The units are cubic centimeters per second. Total N yield: the total yield of dissolved nitrogen discharged from the plot during the duration of the experiment. The units are grams per square meter per l800 sec. This yield has been adjusted, by subtracting the content of total dissolved N applied in the simulated rainfall. Organic N yield: the yield of dissolved organic N, as above. Inorganic N yield: the yield of NH4-N plus NO3-N discharged from the plot during the duration of the experiment, as above. Total P yield: the yield of total dissolved P discharged from the plot during the duration of the experiment. The units are grams per square meter, per l800 sec. Organic P yield: the yield of dissolved organic P, as above. Inorganic P yield: the yield of PO4-P discharged from the plot during the duration of the experiment. Fines: the percent of the plot surface covered by materials < 2.0 mm diameter Gravel: the percent of the plot surface covered by materials > 2.0 mm diameter Vegetation: the percent of the plot surface covered by vegetation. Litter: the percent of the plot surface covered by plant litter. Slope: it was not possible to measure slope in plots with a shrub in them, since the mound dominated the slope in the plot.

Abstract: 

This data set was collected to provide data for comparison of the losses of dissolved nitrogen and phosphorus in the runoff from grass- and shrub- dominated plots in the Jornada Basin of southern New Mexico. This dataset contains the following columns: Plot: the identification number for the plots, which are grouped for grass, shrub or intershrub areas.

Fill Time: the time in seconds used to collect an individual sample of discharge from the plot. Time: the time in minutes (from the beginning of the rainfall simulation) at which each individual collection of discharge began. In each case, the first time listed is the time at which discharge was first observed. Time b/w samples: the time in seconds between the beginning the collection of a given sample of discharge and the beginning of the next collection. Q: the rate of discharge during each collection, in cubic centimeters per second. AveQ/time: the total discharge during an interval in cubic centimeters. For example, the discharge between 16 and 20 minutes is calculated as the mean of the discharge at l6 and 20 minutes multiplied by 4 minutes. InorgN-rain (adjusted inorganic N): the concentration of NH4-N + NO3-N in the discharge sample collected, corrected for the sum of the concentration of these ions in the simulated rainfall applied. Concentration is given in milligrams per liter for N contained in the sum of these forms. Analysis for NH4-N and NO3-N was performed using the Bran-Luebbe Traacs 800 Autoanalyzer, as detailed in Schlesinger et al. (l999). Total N-rain (adjusted total N): the concentration of total dissolved N in the discharge sample collected, corrected for the concentration of total dissolved N in the simulated rainfall applied. Concentration is given in milligrams per liter of total dissolved N in the sample. The concentration of total dissolved N was performed using the Traacs 800 Autoanalyzer, following a persulfate digestion of the sample, as detailed in Schlesinger et al. (l999). OrgN-rain (adjusted organic N): the concentration of N contained in dissolved organic forms, corrected for the concentration of dissolved organic N in the simulated rainfall applied. Dissolved organic N is calculated as the difference, in any sample, between the total dissolved N and the sum of NH4-N and NO3-N. Values are in milligrams per liter. Total P-rain (adjusted total P): the concentration of total dissolved phosphorus, corrected for the concentration of total dissolved phosphorus in the simulated rainfall applied, both in milligrams per liter. Org-P-rain (adjusted org P): the concentration of dissolved organic phosphorus, corrected for the concentration of dissolved organic phosphorus in the simulated rainfall applied, both in milligrams per liter. Inorg-N-rain (adjusted inorganic N), the yield in grams of NH4-N plus NO3-N in the discharge collected. TotalN-rain (adjusted total N), the yield in grams of total dissolved N in the discharge collected. OrgN-rain (adjusted organic N), the yield in grams of forms of dissolved organic N in the discharge collected. Total P-rain (adjusted total P), the yield in grams of total dissolved phosphorus in the discharge collected. OrgP-rain (adjusted organic P), the yield in grams of forms of dissolved organic phosphorus in the discharge collected. InorgN-rain (adjusted inorganic N) load, is the rate of loss, in grams per second, of the sum of NH4-N plus NO3-N during the period of the sample collection. Total N-rain (adjusted total N) load, is the rate of loss, in grams per second, of total dissolved N during the period of the sample collection. OrgN-rain (adjusted organic N) load, is the rate of loss, in grams per second, of dissolved organic N during the period of the sample collection. Total P-rain (adjusted total P) load, is the rate of loss, in grams per second, of total dissolved P during the period of the sample collection. Org-P-rain (adjusted organic P) load, is the rate of loss, in grams per second, of dissolved organic P during the period of the sample collection.

This dataset quantities vegetation cover at experimental hydrology plots on the New Mexico State University Ranch and USDA Jornada Experimental Range. Plots were located in a zone dominated by creosotebush and a zone dominated by grassland. The goal was to compare nutrient losses between shrublands and grasslands. Plant Cover was measured on 20 2 x 2 m hydrology run off plots using quadrats with 10 x 10 cm units. The number of 10x10cm squares occupied each by plant species was counted and scaled up to determine the total percent cover of each species per plot. Best available judgement was used. For instance, dense grass cover of Bouteloua eriopoda was measured while a thin cover of leaves and stems that may have been present over an area was not. With the annual grasses that were inherently sparse, cover was estimated measuring across the width of the plant. However, the central portion of the bunch grasses were measured as cover and not the scraggly leaf/stem material. Nutrient data can be found in package 210001003. This data collection is complete.

This dataset quantities dissolved nutrients in water surface runoff from natural rainfall events at experimental hydrology plots on the New Mexico State University Ranch and USDA Jornada Experimental

This dataset quantities dissolved nutrients in water surface runoff from natural rainfall events at experimental hydrology plots on the New Mexico State University Ranch and USDA Jornada Experimental Range. Chemical analyses include F, Cl, NO3, SO4 by ion chromatography, NH4 by autoanalyzer, Ca, Mg, Na, K by atomic absorption spectrophotometry, and total N and P by auto- analyzer.  Nutrient losses from shrubland plots were greater than from grassland plots. The greater nutrient losses in shrublands were due to higher runoff, rather than higher nutrient concentrations in runoff. This study is complete. Refer to:

Abstract: 

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. Of those 4074 observations, 2745 contained precipitation values greater than zero or contained precipitation values greater than runoff values.

Very few observations showed runoff values greater than precipitation. All values are included here for completeness of the data set. These data were collected and analyzed in the laboratory under the supervision of John Anderson (primarily). Dr. Susan M. Bolton and Dr. Tim J. Ward compiled and checked the data. Tim J. Ward is responsible for the final input, checking and presentation of the data set presented below. Questions about the data should be directed to Tim J. Ward through the Jornada LTER.
