Trace Organic Chemicals in Biosolieds-Amended Soils: State-of-the-Science Review
Christopher P. Higgins,Jonathan O. Sharp,Jennifer G. Sepulvado,BobbiJo Littrell,George A. O'Connor,Erin Snyder,Drew C. McAvoy +6 more
TL;DR: The presence of trace organic chemicals (TOrCs) in municipal biosolids in the U.S. has received considerable attention by the public and scientific community over the last several years as mentioned in this paper.
Journal ArticleDOI
Variation of forage and extractable soil minerals over two grazing seasons in North Florida
TL;DR: A two-year experiment was conducted at a north Florida farm to evaluate the mineral status of bahiagrass forages and soils as mentioned in this paper, where forage samples were collected every 28 d throughout the grazing season, and soils evaluated twice yearly.
Journal ArticleDOI
Runoff and Leachate Phosphorus and Nitrogen Losses from Grass-Vegetated Soil Boxes Amended with Biosolids and Fertilizer
Maria L. Silveira,George A. O'Connor,Yanyan Lu,John E. Erickson,Carolina B. Brandani,Marta M. Kohmann +5 more
TL;DR: Results demonstrate the value of water-extractable P (WEP) as an indicator of biosolids P loss potential and identify and thoroughly characterize the main biosolid sources routinely applied in the region.
Journal ArticleDOI
Effects of aluminum from water-treatment-residual applications to pastures on mineral status of grazing cattle and mineral concentrations of forages
R. K. Madison,Lee Russell McDowell,George A. O'Connor,N.S. Wilkinson,P. A. Davis,Adegbola T. Adesogan,Tara L. Felix,Meghan Brennan +7 more
TL;DR: In this article, the effects of water treatment residuals (WTR) applications to pasture on mineral status of cattle and bahiagrass (Paspalum notatum) were investigated.
Journal ArticleDOI
Biochar impacts on nutrient dynamics in a subtropical grassland soil: 2. Greenhouse gas emissions.
Yanyan Lu,Maria L. Silveira,Michel A. Cavigelli,George A. O'Connor,Joao M. B. Vendramini,John E. Erickson,Yuncong Li +6 more
TL;DR: Data suggested that environmental conditions played a more important role on GHG fluxes than nutrient additions, and biochar reduced CO2 emissions modestly but had no effects on N2 O and CH4 emissions.
