“…However, there was no increase in labile P form (resin-P i plus NaHCO 3 P i and P o ) in the manured soil, indicating P added from manure has entered into relatively more stable forms (moderately labile or stable P) even after only 2 wk of incubation. Transformation of added P (phosphate) from labile to stable P fractions is commonly observed (Hooker et al 1980;Ryan et al 1985a,b;Afif et al 1993;Castro and Torrent 1995). Application of P into the soil may lead to surface adsorption and precipitation of P, which depresses the availability of applied P (Samadi and Gikes 1999).…”

Qian, P. and Schoenau, J. J. 2000. Fractionation of P in soil as influenced by a single addition of liquid swine manure. Can. J. Soil Sci. 80: 561-566. Limited information exists as to the short-term effect of liquid swine manure on P distribution in soil. To address this issue, forms and distribution of inorganic P (P i ) and organic P (P o ) at 2 wk and 16 wk after manure addition were investigated through a sequential extraction procedure. An Orthic Black Chernozem was sampled from a field research plot (Dixon, SK) without previous manure and urea additions. Liquid swine manure and urea were applied at rates of 0, 100 and 400 mg N kg -1 , corresponding 10 and 40 mg P kg -1 from manure. Manure addition did not increase the most labile P fractions in soil. Instead the initial fate of the P from the manure was mainly to enter moderately labile and stable fractions such as calcium phosphate and organic P forms. This is consistent with observations in the field that a single application of swine effluent does not have a large impact on extractable "available" P in the soil. Further studies are needed to determine how much manure P loading is required for saturation of the "fixed pool" of P in Saskatchewan soils.Key words: Phosphorus fractions, sequential P extraction, incubation, urea, swine manure, anion exchange membrane Qian, P. et Schoenau, J. J. 2000. Répartition des formes de P dans le sol après un simple apport de lisier liquide de porc. Can. J. Soil Sci. 80: 561-566. Il existe peu de données sur les effets à court terme du lisier liquide de porc sur la répartition du phosphore (P) dans le sol. Nous avons donc examiné, par une technique d'extraction séquentielle, les formes et la répartition du P minéral (Pm) et du P organique (Po), 2 et 16 semaines après l'épandage du lisier. Nous utilisions un chernozem noir orthique, faisant partie d'un champ expérimental (Dixon, Saskatchewan) n'ayant reçu auparavant ni fumier ni urée. Le lisier de porc et l'urée étaient apportés aux doses de 0, 100 et 400 mg N kg -1 de sol, correspondant à 10 et 40 mg P kg -1 dans le cas des traitements avec lisier. L'apport de lisier ne causait pas d'augmentation des fractions P les plus labiles. Le sort initial du P provenant du lisier était de se lier aux fractions modérément labiles ou stables, comme le phosphate de calcium et les composés organiques de P. Ceci concorde avec les observations faites au champ montrant qu'un apport unique de lisier de porc n'a pas d'impact considérable sur le P «disponible» extractible dans le sol. Il reste à déterminer quelle charge de P sous forme de fumier il faudrait pour saturer le pool fixé de P dans les sols de la Saskatchewan.

“…Soluble P compounds when added to soil react rapidly with various compounds like CaCO 3 (Bertrand et al, 2003), sand (Leclerc et al, 2001), clay (Johnston et al, 1991;Toor et al, 1997), organic matter (Daly et al, 2001), iron and aluminum oxides (Toor et al, 1997) and are quickly converted to slowly available forms (Castro and Torrent, 1995). In addition to these properties, adsorption also depends on contact time between soil and P with temperature (Indiata et al, 1999).…”

“…Surface adsorption and precipitation are the major P retention processes limiting the availability of applied P. However, the need for caution is stressed in interpreting correlation between P retention capacity (Bertrand et al, 2003) and soil properties because of the inter correlations among soil properties (Torrent, 1995). A simple correlation analysis may not be sufficient in evaluating direct influence of soil properties on P retention capacity (Zhang et al, 2005).…”

Phosphorus (P) is the most important element after nitrogen but P sorption properties are poorly documented in many soils. In this study, P sorption capacity in relation to incubation period and temperature under various P levels were determined for two different soil series (Rustam and Miani). Phosphorus was added at 5, 10, 25, 50, 100, 250, 500 and 1000 µg g −1 to the soils and incubated for the period of 1, 3, 7, 15, 30 and 60 days at 25 and 35±1°C temperatures. Phosphorus sorption was significantly influenced by the temperature, added P and incubation period. Clay content has major influence on P sorption. Rustum Series adsorbed more P than that of Miani Series. The P sorption was faster at high temperature (35°C). At the end of period in the Rustum Series with added 2.5 and 1000 µg g −1 P level, P sorption were found 0.7 and 943 µg g −1 , respectively, at 25±1°C temperature, whereas at 35±1°C temperature the respective P sorption for same P levels were 1.8 and 987.0 µg g −1 . In the Miani Series at 25±1°C temperature, P sorption was 0.7 and 941 µg g −1 , while at the temperature of 35±1°C, P sorption were 1.0 and 986 µg g −1 soil. Increasing P levels, temperature and incubation, resulted in higher P sorption. Hence, high clay in combination with calcium carbonate contents enhanced P adsorption, while high organic matter and high native soil P resulted in lesser P adsorption.

“…The reaction of phosphate in calcareous sediments involves complex adsorption and precipitation processes (Delgado et al 2000;Pena and Torrent 1984;Castro and Torrent 1995;Cole et al 1953;Kuo and Lotse 1972). The interaction of phosphate with calcite surfaces consists of rapid monolayer sorption.…”

SummaryThe Hanford Site is a former nuclear defense production facility. A groundwater plume containing uranium, originating from a combination of purposeful discharges of wastewater to cribs, trenches, and ponds, along with some accidental leaks and spills related to nuclear fuel fabrication activities, has persisted beneath the Hanford Site 300 Area for many years. Despite the cessation of uranium releases and the removal of shallow vadose zone source materials, the remedial action objective to lower the concentration of groundwater uranium to the U. S. Environmental Protection Agency maximum contaminant level concentration of 30 µg/L has not been achieved within the anticipated 10-year time period. Some unknown amount of contamination remains in the vadose zone beneath the lower extent of the excavation activities. Additional contamination also may remain beneath buildings and facilities in the southern portion of the 300 Area, which has not been decontaminated and decommissioned. The use of polyphosphate technology for source treatment in the vadose zone and capillary fringe is expected to accelerate the natural attenuation of uranium to thermodynamically stable uranium-phosphate minerals. This effort will complement the current 300 Area treatability test being conducted within the saturated zone (e.g., 300 Area aquifer) for in situ treatment of uranium-contaminated groundwater.Polyphosphate technology has been demonstrated for in situ precipitation of phosphate phases to control the long-term fate of uranium. A critical component of the development and testing is detailed evaluation to determine if polyphosphate technology could be modified for infiltration from ground surface or some depth of excavation to stabilize source uranium phases. This report presents results from bench-scale treatability studies conducted under site-specific conditions to optimize the polyphosphate amendment for implementation of a field-scale technology demonstration to stabilize uranium within the 300 Area vadose zone and capillary fringe of the Hanford Site. Documented in this report are data related to 1) the retardation of polyphosphate as a function of water content and pore water velocity, 2) the reaction between uranium-bearing solid phases and aqueous polyphosphate remediation technology as a function of polyphosphate composition and concentration, 3) the mechanism of autunite formation via the reaction of solid-phase calcite-bound uranium and aqueous polyphosphate remediation technology, 4) the transformation mechanism and reaction kinetics between uranyl-carbonate and -silicate minerals with the polyphosphate remedy under advective conditions, and 5) the extent and rate of uranium released and immobilized as a function of polyphosphate composition and the infiltration rate of the polyphosphate remedy. Kinetic rate law parameters were determined from single-pass flow-through experiments. Pressurized unsaturated flow tests were used to determine the effect of polyphosphate composition, concentration, and infiltration rate...
