From:Agricultural Research (Vol. 44, Issue 12) Peer-ReviewedPlant geneticist Victor Raboy of the US Dept. of Agriculture's Agricultural Research Service has discovered that mutations lower phytic acid in corn without altering the total amount of phosphorus in the plant. Phytic...

From:The Biological Bulletin (Vol. 203, Issue 2) Peer-ReviewedPhytoplankton growth requires nitrogen (N) and phosphorus (P) in an approximate molar ratio of 16:1 (the Redfield ratio; 1). N or P limitation in an aquatic system is considered to occur when the availability of N...
-
From:PLoS ONE (Vol. 11, Issue 11) Peer-ReviewedAgricultural production can be limited by low phosphorus (P) availability, with soil P being constrained by sorption and precipitation reactions making it less available for plant uptake. There are strong links between...
-
From:PLoS ONE (Vol. 13, Issue 8) Peer-ReviewedPhosphorus (P) is arguably more limiting than nitrogen for forest ecosystems being free of disturbances for lengthy time periods. The elucidation of multivariate relationships between foliar P and its primary drivers...

From:Australian Journal of Soil Research (Vol. 38, Issue 2) Peer-ReviewedThe brown kandosol soils at Weipa, North Queensland, contain little soil phosphorus (P). Plant-available fractions (considered in this study to include resin, hydroxide, and dilute acid extractable P) approximate 85...

From:Indian Journal of Pharmacology (Vol. 43, Issue 3) Peer-ReviewedByline: Anupama. Mauskar, Kunal. Mehta, Leena. Nagotkar, Preeti. Shanbag We report a case of three year old girl, who was brought to hospital for accidental consumption of rat-poison (3% phosphorus). The patient was...

From:Science (Vol. 223) Peer-ReviewedOf the six major plant nutrients, phosphorus is typically one of the most tightly conserved within forested ecosystems. Hydrologic exports of dissolved inorganic phosphorus (DIP) with stream water and deep seepage...
-
From:Canadian Journal of Civil Engineering (Vol. 36, Issue 7) Peer-ReviewedIn-line addition of alum and ferric chloride was conducted at a hollow-fibre immersed ultrafiltration (UF) membrane pilot plant, using secondary effluent from a municipal wastewater treatment plant (WWTP) as the feed....
-
From:Biogeosciences (Vol. 14, Issue 2) Peer-ReviewedThe balance in microbial net consumption of nitrogen and phosphorus was investigated in samples collected in two mesotrophic coastal environments: the Baltic Sea (Tvärminne field station) and the North Sea...
-
From:Soil Research (Vol. 49, Issue 3) Peer-ReviewedThis paper describes the effects of chemical fertiliser and pig manure application on the phosphorus (P) balance and changes of soil organic P ([P.sub.o]) fractions in a Mollisol following 14 years of...
-
From:Journal of Soil and Water Conservation (Vol. 60, Issue 4) Peer-ReviewedIrrigation of agricultural land is important for food production in the United States. Only 15 percent of the harvested cropland in the United States is irrigated, but almost 40 percent of the crop value is produced...
-
From:Agricultural Research (Vol. 54, Issue 8) Peer-ReviewedLagoons are commonly used to store wastewater from confined-feeding operations for dairy and swine. The wastewater is generally applied to land as fertilizer. But if the waste is not applied properly, excess nitrogen...
-
From:Chemical EngineeringPeer-ReviewedBy the end of this year, a demonstration plant will start up in the U.S. that uses an electrochemical process to recover phosphorus from wastewater, producing a fertilizer as struvite (NH4MgPO4*6H2O). Although the...

From:Science (Vol. 305, Issue 5690) Peer-ReviewedEvery summer, death stalks the waters of the northern Gulf of Mexico. A New Jersey-size swath of sea becomes depleted of oxygen, suffocating millions of crabs and other denizens of the sea floor. In 1999, the federal...
-
From:Ecological Applications (Vol. 9, Issue 3) Peer-ReviewedAbstract. We analyzed management policies for ecosystems subject to alternate states, thresholds, and irreversible changes. We focused on the problem of lake eutrophication by excessive phosphorus (P) input. Eutrophic...
-
From:Canadian Journal of Forest Research (Vol. 46, Issue 5) Peer-ReviewedMasson pine caterpillar (MPC, Dendrolimus punctatus Walker) outbreaks periodically occur in Masson pine (Pinus massoniana Lamb.) plantations in southern China; however, their effects on nutrient cycling remain unclear....
-
From:Canadian Journal of Forest Research (Vol. 36, Issue 8) Peer-ReviewedAbstract: Phosphorus (P) availability was investigated in rhizosphere soils under 4- to 5-year-old, second-rotation Pinus radiata D. Don and understorey grass (browntop, Agrostis capillaris L.) in two P-deficient...
-
From:Canadian Journal of Chemistry (Vol. 95, Issue 11) Peer-ReviewedAbstract: A solution method was developed to synthesize reduced graphene oxide (RGO)--red phosphorous (RP) composites. The uniform distribution of RP particles into tliree-dimensional conductive RGO network was...

From:Chemical EngineeringPeer-ReviewedA project has been announced to demonstrate Microvi's (Hayward, Calif.; www.microvi.com) pollutant-removal-and-recovery technology for phosphorus in water. The objective of the demonstration is to reduce total...
