“…Surprisingly, the slopes of the regression lines between PSI and Mehlich 3 Al were not statistically different in the five different solution treatments (P , 0.05). It is not uncommon for metal oxides to play a strong role in P sorption in noncalcareous soils (Berkheiser et al 1980;Hsu 1964; Van der Zee and Van Riemsdijk 1986), though unlike our study most of these correlations have been observed with oxalate-extractable Al instead of Mehlich 3-extractable Al (Beauchemin et al 2003;Borggaard et al 1990;Borling, Otabbong, and Barberis 2001;Burkitt et al 2006;Kleinman and Sharpley 2002;Pierzynski et al 1990;Traina et al 1986). …”

“…Solution pH has been shown to be an important factor controlling P sorption to soils (Amarasiri and Olsen 1973;Barrow 1983;Traina et al 1986;Violante, Colombo, and Buondonno 1991). Solution pH determines the ratio of the different orthophosphate species, the charge at the soil surface, and the dominant soluble metallic-phosphate complex species (Berkheiser et al 1980). Increased pH can decrease sorption by decreasing the electrostatic potential at the surface ) and neutralizing Fe and Al oxides.…”

“…Important differences between manure and CaCl 2 and KCl solutions expected to affect P sorption to soils include manure organic-matter content, pH, and ionic composition (Berkheiser et al 1980). The presence of organic matter can alter P sorption behavior by competing for sorption sites, causing the dissolution of aluminum (Al) and iron (Fe) oxides, increasing the overall negative charge at the surface, and serving as a site for P sorption (Guppy et al 2005b;Ohno and Crannell 1996).…”

In most phosphorus (P) sorption studies, P is added as an inorganic salt to a predefined background solution such as calcium chloride (CaCl 2 ) or potassium chloride (KCl); however, in many regions, the application of P to agricultural fields is in the form of animal manure. The purpose of this study, therefore, was to compare the sorption behavior of dissolved reactive P (DRP) in monopotassium phosphate (KH 2 PO 4 )-amended CaCl 2 and KCl solutions with sorption behavior of DRP in three different animal manure extracts. Phosphorus single-point isotherms (PSI) were conducted on eight soils with the following solutions: KH 2 PO 4 -amended 0.01 M CaCl 2 solution, KH 2 PO 4 -amended 0.03 M KCl solution, water-extracted dairy manure, water-extracted poultry litter, and swine lagoon effluent. The PSI values for the dairy manure extract were significantly lower than the CaCl 2 solution for all eight soils and lower than the KCl solution for six soils. The PSI values were significantly higher, on the other hand, for poultry litter extract and swine effluent than the inorganic solutions in four and five of the soils, respectively. Our observations that the sorption of DRP in manure solutions differs significantly from that of KH 2 PO 4 -amended CaCl 2 and KCl solutions indicates that manure application rates based on sorption data collected from inorganic P salt experiments may be inaccurate.

“…Sorption is envisioned as a two-step process in which a rapid phase corresponds to initial retention on a surface and a slower phase corresponding to diffusion into a solid phase involved in sorption (Barrow, 1983 a,b;Portielje and Lijklema, 1993). Several reviews have discussed the mechanisms of P sorption in acid soils by Al and Fe and in alkaline soils by Ca and Mg compounds (Syers et al, 1973;Berkheiser et al, 1980;Bostrom et al, 1982;Logan, 1982;Sonzogni et al 1982;Froelich, 1988;Sanyal and DeDatta, 1991). The above reviews indicate that several phosphate minerals regulate the solubility of dissolved P in the interstitial waters, soils, and sediments.…”

Phosphorus (P) is often the key nutrient found to be limiting in both estuarine and freshwater ecosystems. As such, the ability of wetlands and streams to retain P is key to determining downstream water quality. This article reviews the processes and factors regulating P retention in streams and wetlands and evaluates selected methodologies used to estimate P retention in these systems. Phosphorus retention mechanisms reviewed include uptake and release by vegetation, periphyton and microorganisms; sorption and exchange reactions with soils and sediments; chemical precipitation in the water column; and sedimentation and entrainment. These mechanisms exemplify the combined biological, physical, and chemical nature of P retention in wetlands and streams. Methodologies used to estimate P retention include empirical input-output analysis and mass balances, and process kinetics applied at various scales, including micro-and mesocosms to full-scale systems. Although complex numerical models are available to estimate P retention and transport, a simple understanding of P retention at the process level is important, but the overall picture provided by mass balance and kinetic evaluations are often more useful in estimating long-term P retention.

“…A transferência de P para o ambiente hídrico ocorreu tanto nas formas inorgânicas como orgânicas, dissolvidas e particuladas, conforme relatado por MCDOWELL et al (2001) (BERKHEISER et al, 1980;SHARPLEY, 1995;NOVAIS et al, 2007). Essa justificativa é compatível com os resultados de SILVA et al (1997), os quais demonstraram correlação inversa entre a CTC e a MO e direta entre H+Al e a adsorção de P.…”

RESUMOO aporte de fósforo (P) no escoamento superficial em áreas fertilizadas está associado à eutrofização dos corpos de água. Para estudar as transferências de P para o ambiente hídrico foram avaliadoso solo, a água de enxurrada, os sedimentos e o solo de um Latossolo de textura argilosa que tem recebido aplicação de adubo mineral e de lodo de esgoto. Na enxurrada foram determinadas as concentrações de P dissolvido (inorgânico e orgânico), particulado e total. Nos sedimentos, determinaram-se os teores de P disponível e P total. No solo, além do P-Resina, foram avaliados os teores de Al, Fe e P para estimar a capacidade de adsorção de P (CAP) e o grau de saturação de P (GSP) do solo. A aplicação de lodo aumentou os teores de P no solo refletindo no aumento do GSP. Os teores de P detectados na enxurrada não se correlacionaram com o GSP e os altos teores de P no solo que recebeu lodo não contribuíram para aumentar seu transporte. As intensidades das chuvas não influenciaram as concentrações das formas de P na enxurrada onde houve aplicação de lodo de esgoto. As perdas totais de P pela erosão foram maiores na enxurrada do que nos sedimentos arrastados.Palavras-chave: agricultura, eutrofização, resíduo orgânico, qualidade da água. ABSTRACT TRANSPORT OF PHOSPHORUS BY RUNOFF IN A TYPIC HAPLORTOX WHERE SEWAGE SLUDGE WAS APPLIEDThe input of phosphorus (P) in the runoff of fertilized agricultural soils is associated with the eutrophication of water bodies. In order to study P transference from a Typic Haplortox to the water bodies the runoff, sediment, and soil samples of an experimental field were evaluated after application of mineral fertilizer and sewage sludge. The amounts of dissolved organic and inorganic, particulate and total P in runoff were evaluated. Total and available P were measured in sediments. In the soil, besides resin P, the extracted levels of Al, Fe, and P were also evaluated, for estimating P adsorption capacity (PAC) and the degree of P saturation (DSP). The application of sewage sludge increased the levels of P in soil resulting in an increase of DSP. The levels of P detected in the runoff did not correlated to DSP and high levels of P in the soil with sewage sludge do not increased its transportation. Rainfall intensity had no effect on the concentrations of P forms in runoff of soils with application of sewage sludge. The total P losses by erosion were higher in runoff than in sediments.
