Abstract:

The aim of this research was to examine the spatial and temporal variation in export control points of nitrogen on residential lawns (locations prone to mobilizing nitrogen during a rain event) and to examine if previously measured hydrobiogeochemical properties were predictive of N mobilization in lawns.

This data set contains measurements of saturated infiltration rates, sorptivity, soil moisture, soil organic matter, bulk density, pH, soil nitrate, soil ammonium, N2O, N2 and CO2 fluxes from soil cores, nitrogen mineralization rates and fluxes of N in runoff and leachate from fertilized and unfertilized residential and institutional lawns. Study lawns were located at homes of people who agreed to volunteer their lawn for the study from a door knocking campaign. Four sampling houses were located in an exurban neighborhood in Baisman Run. Five sampling houses were located in a suburban neighborhood in Dead Run. Two sampling locations on institutional lawns were located at University of Maryland Baltimore County. At the exurban study houses and institutional lawns sites, we identified one hillslope to conduct sampling on. At the Dead Run houses we identified one hillslope on the front yard and one in the backyard as there were distinct locations that were not present in the exurban neighborhood. Locations within the yards for sampling were selected based on sampling conducted in October 2017. Locations were grouped into four categories based on have either high or low potential denitrification rates and high or low saturated infiltration rates (n=48). These locations were also distributed across yard types (exurban, suburban or institutional), fertilizer treatments, and hillslope location (top or bottom of hillslope). At each sampling location we ran a Cornell Sprinkle Infiltrometer to generate an experimental rainfall during which we collected runoff and leachate to quantity N flux. We also measure sorptivity and saturated infiltration rates. Volumetric water content was measured before and after infiltrometer runs with a Field Scout TDR 300 with 7.5 cm rods. In addition, at each sampling location we took two soil cores to 10 cm depth to measure gaseous N flux and soil N processes. Soil cores were stored on ice in the field, and then stored at 4°C in the lab until processed for variables mentioned above. Sampling was conducted across four seasons (April 2018, September 2018, November 2018 and March 2019) to capture seasonal variability including the timing of fertilizer applications.

Methods and protocols used in the collection of this data package

Description:

Cornell Sprinkle Infiltrometers were run using the method described in their manual (http://soilhealth.cals.cornell.edu/cornell-sprinkle-infiltrometer/). During the run of the infiltrometers runoff was collected and concentrations of NO3– and NH4+ were measured. These were transformed to fluxes of N/m2/hour. Leachate was also collected during the infiltrometer run using macrorhizons. Leachate flux was calculated for a volume of leachate standardized to initial soil moisture of 25% and rainfall rate of 20 cm/hr. We did this because leachate fluxes were correlated to leachate volume, thus suggesting that changes in initial soil moisture or differences in rainfall rates could affect theses estimates. Soil moisture was determined gravimetrically Soil organic matter was determined by mass loss on ignition for 4 hours at 450°C. Soil NO3- and NH4+ was determined by shaking 7.5 g (wet weight) soil with 30 mL 2M KCl for 1 hour. KCl extract was then filtered through pre-leached Whatman 42 ashless filters and stored at 4°C until analyzed colorimetrically on a Lachat QC8000 flow-injection analyzer. N2, N2O and CO2 fluxes were determined using the nitrogen-free air recirculation method. Net nitrogen mineralization and nitrification were determined by incubation of 10 g (wet weight) soil for 10 days in 946 mL “mason” jars. After the incubation period, soil NO3- and NH4+ were extracted by shaking with 40 mL 2M KCl for 1 hour. KCl extract was collected and analyzed for NO3- and NH4+ as described above. Net nitrogen mineralization was calculated as the change in soil NH4+ plus the change in soil NO3- over the 10 day incubation period. Net nitrification was calculated as the change in soil NO3- over the 10 day incubation. Gas samples were also collected as the start and end of the incubations and were analyzed on a Shimadzu GC2014 gas chromatograph for CO2 concentration. Slope was estimated inside the infiltrometer ring after installation using a smart phone level application. Volumetric water content pre and post infiltrometer runs were measured with a Field Scout TDR 300 with 7.5 cm rods. Bulk density was determined by weighing a dried soil core used for the nitrogen-free air recirculation method and dividing by the volume of the core.
