Phosphorus lability across diverse agricultural contexts with legacy sources
Journal of Environmental Quality, EarlyView.Abstract The buffering of phosphorus (P) in the landscape delays management outcomes for water quality. If stored in labile form (readily exchangeable and bioavailable), P may readily pollute waters. We studied labile P and its intensity for >600 soils and sediments across seven study locations in the United States. Stocks of labile P were large enough

A 500 kpc HI Tail of the Virgo Pair NGC4532/DDO137 Detected by ALFALFA [PDF]
, 2007 HI observations of the Virgo Cluster pair NGC 4532/DDO 137, conducted as part of the Arecibo Legacy Fast ALFA Survey (ALFALFA), reveal an HI feature extending ~500 kpc to the southwest. The structure has a total mass of up to 7 x 10^8 solar masses, equivalent to 10% of the pair HI mass.

Journal of Environmental Quality, EarlyView.Abstract Quantification of Escherichia coli in water is commonly used to understand a surface source's suitability for produce irrigation. Location, season, and physicochemical water quality impact the levels of E. coli in irrigation ponds. Water samples were collected periodically at three ponds in Southeast Georgia along a sampling grid from July ...

Effect of Replacing Alfalfa Hay with Alfalfa Silage in High Performance Dairy Cattle Diets
پژوهشهای علوم دامی ایران, 2014 Four-handed fifty lactating Holstein cows with mean body weight of, 597± 40 and 50±20 and days in milk body Condi from sure of 3.1±0.4 were blocked by parity and randomly assigned to 3 treatments. Each treatment had 3 pens and each pen had 50 cows.

The Effect of Halo Mass on the HI Content of Galaxies in Groups and Clusters [PDF]
, 2015 We combine data from the Sloan Digital Sky Survey (SDSS) and the Arecibo Legacy Fast ALFA Survey (ALFALFA) to study the cold atomic gas content of galaxies in groups and clusters in local universe. A careful cross-matching of galaxies in the SDSS, ALFALFA and SDSS group catalogs provides a sample of group galaxies with stellar masses $10^{8.4} M_{\odot}

Evaluating the potential for snowmelt phosphorus losses from perennial forage crops
Journal of Environmental Quality, EarlyView.Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...
