Increased residential demolitions have made vacant lots a ubiquitous feature of the contemporary urban landscape. Vacant may provide ecosystem services such as stormwater runoff capture, but extent these functions will be regulated by soil hydrology. We evaluated physical and hydrologic characteristics at each low- (backyard, fenceline) high-disturbance (within demolition footprint) positions in 52 Cleveland, OH, which were result different eras process quality (i.e., pre-1996, post-1996)....
Combining horizontal drilling with high volume hydraulic fracturing has increased extraction of hydrocarbons from low-permeability oil and gas (O&G) formations across the United States; accompanied by wastewater production. Surface water discharges O&G centralized waste treatment (CWT) plants pose risks to aquatic human health. We evaluated impact surface disposal CWT upstream Conemaugh River Lake (dam controlled reservoir) in western Pennsylvania. Regulatory compliance data were collected...
Determining the gypsum content in soil is lengthy and cumbersome using methods based on SO 4 determination. Moreover, as these do not strictly titrate gypsum, inaccuracies can be produced by presence of sulfate minerals other than gypsum. The thermogravimetric properties however, allow determination its a rapid easy way sufficiently accurate for many pedologic purposes. Our objective was to expand lower limit detection make test useful classification management. We have refined differential...
Abstract Because of climate change, insufficient soil moisture may increasingly limit crop productivity in certain regions the world. This be particularly consequential for biofuel crops, many which will likely grown drought‐prone soils to avoid competition with food crops. Biochar is byproduct a production method called pyrolysis. If pyrolysis becomes more common as some scientists predict, biochar become widely available. We asked, therefore, whether addition could significantly increase...
The availability of light detection and ranging data (LiDAR) has resulted in a new era landscape analysis. For example, improvements LiDAR resolution may make it possible to accurately model microtopography over large geographic area; however, processing costs versus resulting accuracy be too costly. We examined two datasets differing resolutions, low point density (0.714 points/m 2 spacing) 1 m DEM available statewide Pennsylvania high (10.28 research-grade DEM, compared the calculated...
Worldwide, shale-gas development is becoming a feasible extraction practice and the northern Allegheny Plateau, USA region experiencing such development. We used GIS to investigate topographic soil characteristics across existing permitted pads in Pennsylvania, which could affect infrastructure reclamation success. Results from this analysis, while regionally specific, can contribute knowledge for successful management of all extraction. Approximately 60% occur on slopes at risk some excess...
Amending soils with biochar can sequester C and improve soil properties, such as nutrient holding capacity water retention. While biochars generally have a long residence time in soil, the turnover of be influenced by both characteristics properties. Biochar also potentially alter rate decomposition native organic matter (SOM). The switchgrass (Panicum virgatum L.)-derived was evaluated laboratory using from four marginally productive sites central Pennsylvania. Carbon dioxide emissions...
The evolution of phosphorus (P) management decision support tools (DSTs) and systems (DSS), in food environmental security has been most strongly affected developed regions by national strategies (i) to optimize levels plant available P agricultural soils, (ii) mitigate runoff water bodies. In the United States, Western Europe, New Zealand, combinations regulatory voluntary strategies, sometimes backed economic incentives, have often driven reactive legislation protect Farmer‐specific DSSs,...
Strawberry (Fragaria × ananassa Duch.) has a unique flavor and nutritional value. To investigate the effects of deficit irrigation on growth, yield, quality, water use efficiency strawberries, “Zhangji” “Hongyan” varieties were assessed in greenhouse. Four levels set as 95% (CK), 75% (LS), 55% (MS), 35% (±5%) (SS) field capacity, respectively. Five successive plant growth stages analyzed. The results indicate that plants’ daily consumption intensity, well fruit yield titratable acidity,...
Soil salinization is a difficult challenge for agricultural productivity and environmental sustainability, particularly in arid semi-arid coastal regions. This study investigates the spatial variability of soil electrical conductivity (EC) its relationship with key cations anions (Na+, K+, Ca2+, Mg2+, Cl⁻, CO32⁻, HCO3⁻, SO42⁻) along southeastern coast Caspian Sea Iran. Using combination field-based sampling, laboratory analyses, Landsat 8 spectral data, linear Multiple Linear Regression...
