“…The Webster (fine‐loamy, mixed, superactive, mesic Typic Endoaquolls) series consists of very deep, poorly drained, moderately permeable soils formed in glacial till or local alluvium derived from till on uplands (USDA, 1996; Konen et al, 2003; Reuter and Bellb, 2003). Slope ranges from 0 to 3%.…”

A batch reactor was used to determine sorption kinetic parameters (k2, F, and K*) and the equilibrium sorption coefficient (K). The two-site nonequilibrium (TSNE) batch sorption kinetics model was used to calculate the kinetic parameters. Two probe organic pesticides, atrazine [2-chloro-4-ethylamino-6-isopropylamino-s-triazine] and diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea] were studied using three carbonatic soils from South Florida (Chekika, Perrine, and Krome), one noncarbonatic soil from Iowa (Webster), and one organic soil (Lauderhill) from South Florida. Carbonatic soils contained more than 600 g kg(-1) CaCO3. Sorption is initially very fast up to 3 h and then slowly reaches equilibrium. All soil-chemical combinations reached sorption equilibrium after about 24 h and all sorption isotherms were linear. The sorption kinetics data were well described by the TSNE model for all soil-chemical combinations except for the marl soil data (Perrine-Atrazine), which were better described by the one-site nonequilibrium (OSNE) model. Diuron, with higher K, undergoes slower sorption kinetics than atrazine. The Lauderhill soil containing organic carbon (OC) of 450 g kg(-1) exhibited slowest sorption kinetics for both pesticides. An inverse relationship between k3 and K was observed for atrazine and diuron separately in Chekika, Webster, and Lauderhill soils but not in Perrine and Krome soils. The sorption kinetic parameters were used to distinguish the sorption behavior between atrazine and diuron and to identify differences between soils. Normalizing the sorption coefficient (K) to OC showed that atrazine and diuron had K oc values in carbonatic soils that were a third of reported literature values for noncarbonatic soils. Using existing literature K oc values in solute transport models will most likely underestimate the mobility of atrazine, diuron, and other neutral organic chemicals in carbonatic soils.

“…Despite the common occurrence of drained closed depressions and the potential for elevated nutrient loading resulting from their inherent hydrologic connectivity with surface waters, few studies have evaluated rainfall–run‐off response in these landforms. Several studies have reported on relationships between water table fluctuations and soil morphology across soil catena sequences (James & Fenton, ; Khan & Fenton, ; Reuter & Bell, ; Steinwand & Fenton, ), water table fluctuations and depression ponding (Logsdon, ; Logsdon et al, ; Roth & Capel, ; Schilling, Jacobson, Streeter, & Jones, ), and the fill‐spill surface hydrology in both drained (Amado, Politano, Schilling, & Weber, ) and natural (undrained) wetland complexes (Huang, Young, Abdul‐Aziz, Dahal, & Feng, ; Shaw, Vanderkamp, Conley, Pietroniro, & Martz, ). Results from this previous work suggest that antecedent conditions play an important role in regulating depression hydrology, yet experimental evidence of the impact of precipitation inputs and antecedent soil moisture on producing event run‐off and hydrological connectivity in drained landscapes is uncommon (Bauwe, Tiemeyer, Kahle, & Lennartz, ; Heppell, Worrall, Burt, & Williams, ; Vidon & Cuadra, ).…”

Hydrological threshold behaviour has been observed across hillslopes and catchments with varying characteristics. Few studies, however, have evaluated rainfall-run-off response in areas dominated by agricultural land use and artificial subsurface drainage. Hydrograph analysis was used to identify distinct hydrological events over a 9year period and examine rainfall characteristics, dynamic water storage, and surface and subsurface run-off generation in a drained and farmed closed depression in north-eastern Indiana, USA. Results showed that both surface flow and subsurface tile flow displayed a threshold relationship with the sum of rainfall amount and soil moisture deficit (SMD). Neither surface flow nor subsurface tile flow was observed unless rainfall amount exceeded the SMD. Timing of subsurface tile flow relative to soil moisture response on the shoulder slope of the depression indicated that the formation and drainage of perched water tables on depression hillslopes were likely the main mechanism that produced subsurface connectivity. Surface flow generation was delayed compared with subsurface tile flow during rainfall events due to differences in soil water storage along depression hillslopes and run-off generation mechanisms.These findings highlight the substantial impact of subsurface tile drainage on the hydrology of closed depressions; the bottom of the depression, the wettest area prior to drainage installation, becomes the driest part of the depression after installation of subsurface drainage. Rapid connectivity of localized subsurface saturation zones during rainfall events is also greatly enhanced because of subsurface drainage. Thus, less fill is required to generate substantial spill. Understanding hydrologic processes in drained and farmed closed depressions is a critical first step in developing improved water and nutrient management strategies in this landscape.

“…The few studies that have investigated topographically stratified sites (Ball et al, ; Pennock et al, ) have excluded subsurface hydrologic interactions or focused solely on aboveground water movement (i.e., rainfall; Austin et al, ; Silver et al, ; Wood & Silver, ). Topographic uplands—above the riparian zone, and outside the hyporheic zone—tend to have greater fluxes of N 2 O along lower slope positions because they tend to collect water (Yanai et al, ) and generally have increased concentrations of soil N and organic C (Groffman et al, ; Reuter & Bell, ). Denitrification in poorly drained soils, such as those common to valley floor positions, has been shown to generate relatively more N 2 O than in well‐drained soils often found in ridgetop positions (e.g., Groffman et al, ).…”

Nitrogen Budget and Topographic Controls on Nitrous Oxide in a Shale‐Based Watershed

The high spatial and temporal variabilities of nitrous oxide (N2O) emissions from the soil surface have made it difficult to predict flux patterns at the ecosystem scale, leading to imbalances in nitrogen (N) budgets at all scales. Our research sought to quantify topographic controls on the sources or sinks of N2O in the soil profile to improve our ability to predict soil‐atmosphere N2O fluxes and their contribution to watershed N budgets. We monitored surface‐to‐atmosphere N2O fluxes for 2 years in the Susquehanna Shale Hills Critical Zone Observatory in central Pennsylvania. Topographically convergent flow path locations had significantly higher surface N2O flux rates than nonconvergent flow path locations in the summer, but not other seasons. Overall, N2O fluxes were a large percentage (~19%) of total ecosystem N losses, and nearly twice as large as stream N export. Surface N2O fluxes were better correlated with concentrations of O2, N2O, and NO3− in shallow soil layers (<30 cm) than deeper soils. Following decades of anthropogenic atmospheric deposition and additional N from shale weathering, watershed N inputs (~8 kgN ha−1 yr−1) are greater than outputs (~3.7 kgN ha−1 yr−1). Our research revealed patterns of N cycling that are distinct from many other watersheds that have been extensively studied to understand N saturation; despite showing no other symptoms of N saturation, the watershed had high upland N2O losses, especially in convergent flow paths during summer. High upland N gas losses may be a mechanism that maintains N limitation to biota in the Shale Hills catchment.
