- Abstract:
- ... Hurricane Harvey (Harvey) struck the Texas coast 25–27 August, 2017, and produced massive flooding of the Galveston Bay tributaries. The slow release of floodwaters from the Barker and Addicks Reservoirs, west of Houston, produced a 48-day flood across metro-Houston through via Buffalo Bayou, through the San Jacinto Estuary (SJE), before flowing into Galveston Bay. To quantify the thickness and ma ...

- Abstract:
- ... Experiments were conducted to evaluate the impact of 36 years of no-tillage (NT), compared to conventional-tillage (CT), on soil physical properties in a continuous grain sorghum experiment. Results revealed that long-term tillage treatments had minimal impact on bulk density (BD), total porosity (TP), air-filled porosity (AFP), water-filled pore space (WFPS), and volumetric water content (Θv). Ho ...

- Abstract:
- ... Seagrass meadows are carbon (C) sinks and nitrogen (N)-limited ecosystems that experience degradation from climate change and anthropogenic stressors, including prop-scarring disturbances by boating vessels. To better understand the variability in C and N pools of undisturbed seagrass soils and the recovery of these pools following boat propeller scarring, we quantified organic carbon (Cₒᵣg) and N ...

- Abstract:
- ... Soil organic matter (SOM) accumulation and carbon (C) sequestration are ecosystem services (ESs) provided by urban landscapes that are dominated by continuous grass cover, such as residential lawns. Organic matter and C sequestration are expected to increase over time, but few studies have determined potential soil organic carbon (SOC) accumulation from residential lawns in semiarid climates. The ...

- Abstract:

A field study in Randall County, Texas, was conducted to determine how soil bulk density and plant cover change over time in response to deferment following a high-density, high-intensity, short-term grazing/trampling event. Green Sprangletop (Leptocloa dubia Kunth.) and Kleingrass (Panicum coloratum L.) were broadcasted at 4.5 kg ha⁻¹ pure live seed (PLS) on former cropland that had a partial sta ...

- Abstract:
- ... Adoption of conservation tillage in cotton cropping systems lags well behind other major crops in the United States. The Texas High Plains region is the largest cotton-producing region in the United States and is in an area where soil and water conservation are of utmost importance. There is little information of the impacts of conservation tillage on soil function within this environment, and lon ...

- Abstract:
- ... The spatiotemporal variability of soil water content (SWC) at the remote sensing scale requires dense monitoring for calibration and validation. Here, we present an overview of the Texas Soil Observation Network (TxSON), an intensively monitored area in the semiarid rangelands of the central Texas Hill Country. TxSON is a dense network consisting of 40 in situ locations nested at 36, 9, and 3 km w ...

- Abstract:

Proximal sensing, such as electromagnetic induction, has been used to map the spatial distribution of soil properties; however, the response of these instruments to short-interval variability associated with Vertisols has not been studied. Meter-scale circular landscape features called gilgai, which are associated with surface and subsurface variability, make sampling these soils difficult, especi ...

- Abstract:
- ... Topography exerts critical controls on many hydrologic, geomorphologic and biophysical processes. However, many watershed modelling systems use topographic data only to define basin boundaries and stream channels, neglecting opportunities to account for topographic controls on processes such as soil genesis, soil moisture distributions and hydrological response. Here, we demonstrate a method that ...

The ASD of cropland varies through time primarily due to the effects of management and climatic factors. A method of predicting ASD is needed to make accurate estimates of wind erosion. The effects of tillage on ASD are described and models proposed to estimate chan ...
