“…Similar increases were also observed for Fe. The release of Al and Fe into solution has been attributed to the dissolution of metal oxides by organic matter (Bhatti, Comerford, and Johnston 1998;Bolan et al 1994;Fox, Comerford, and McFee 1990) and is supported by our observation of minimal release of Fe and Al for the CaCl 2 solution, which lacked DOM, and the swine effluent solution, in which minimal DOC sorption was observed. The greater release of Al in the KCl solution as compared to the CaCl 2 solution was likely due to the higher concentration of K and the fact that K has been shown to be more effective than Ca in displacing Al from soils (Chung, Zasoski, and Burau 1994).…”

“…For the most part, the amount of DOC sorbed to the soils was similar between the dairy and poultry extracts and with little or no DOC sorption occurring with the swine effluent (Figure 3).The large amount of sorption of DOC in the dairy manure solution may explain why DRP sorption was much lower in this solution compared to the CaCl 2 and KCl solutions. Organic matter has been shown to reduce P sorption to soils by competing with P for sorption sites as well as complexing with metal oxyhydroxides (Bhatti, Comerford, and Johnston 1998;Ohno and Crannell 1996;Ohno and Erich 1997;Singh and Jones 1976;Violante, Colombo, and Buondonno 1991). On the other hand, studies have also reported increased P sorption due to the presence of organic matter (Guppy et al 2005a;Harter 1969;Redding, Shatte, and Bell 2006; Sanyal, De Datta, and Chan 1993).…”

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.

“…In a recent study of German forest soils performed with P K-edge XANES spectroscopy, Prietzel et al (2016b) reported the presence of crystalline AlPO 4 in the bedrock of, e.g., BBR (24% AlPO 4 ) and MIT (35% AlPO 4 ). During pedogenesis, the adsorbed P inorg can be desorbed through displacement of other soil 30 solution anions (Bhatti et al, 1998;Violante and Pigna, 2002). The spatial pattern of P ox.inorg at BBR, CON, MIT illustrates this desorption during early and intermediate stages of pedogenesis (Fig.…”

Abstract. The stage of pedogenesis is a crucial indicator describing phosphorus (P) distribution, but also governing spatial 10 P distribution patterns. Here, we assessed spatial patterns of P fractions and major P binding partners (e.g. organic C, pedogenic Fe and Al minerals) in a geosequence to describe spatial and pedogenetic changes of P distribution and to identify mechanisms for these changes. We found, that the distribution of total P was generally best matched by the distribution pattern of organic P, both showing decreasing content from the top-to the subsoil. Inorganic P was mainly ascribed as bound in unweathered rock at all sites, but with decreasing importance in later stages of pedogenesis. The pedogenetically young 15 soil at Bad Brückenau also showed adsorbed inorganic P in the topsoil, probably due to high mineralization of organic P.Soil organic matter (SOM)-sesquioxide-complexes, as well as Al and Fe oxyhydroxides were identified as main binding partners of organic P at all stages of pedogenesis. With depth, the correlations of various P fractions with SOM decreased, whereas those with pedogenic Fe and Al oxyhydroxides increased. The change of sorbent is due to the mobilization of first Al, and in later stages of pedogenesis, of Fe in the topsoil. Both metals and its oxyhydroxides (Al(OH) i , Fe(OH) i ) probably 20 formed strong complexes with SOM and therefore retained P in the pedon. Due to the heterogeneous P distribution, our results suggest a differing ecosystem P nutrition strategy at each of our sites: from acquiring inorganic P from weathered primary rock to minimizing loss of organic P by recycling. We argue that even in early stages of pedogenesis, P recycling is a major driver of ecosystem P nutrition, however not as important as in later stages. We conclude that the stage of pedogenesis in silicate soils, as e.g. visible in degree and state of podzolization, serves as predictor for plant and microbial P 25 nutritional strategies.

“…The phenomenon that adsorbed As(V) were more easily desorbed in the presence of oxalate or HA could be attributed to the reduction in sorption sites because of the effects of oxalate or HA on the soil surface characteristics (Kaiser and Guggenberger, 2003). In addition, the oxalate or HA sorbed on the subsamples could be released into the solution in the desorption process (Sibanda and Young, 1986;Bhatti et al, 1998a;Violante and Pigna, 2002) and thus would also facilitate As(V) desorption.…”

Abstract. Studies on arsenate (As(V)) sorption and desorption have been mainly limited to soil minerals and sorption and desorption reactions in whole soils are poorly understood. In this study the sorption of As(V) by and phosphate-induced desorption from a Chinese red soil were studied in the presence of oxalate and humic acid (HA). Arsenate was strongly sorbed mainly through ligand exchange reactions on the soil. Arsenate sorption decreased in the presence of oxalate or HA. Oxalate and HA influenced As(V) sorption mainly by competing for sorption sites and reducing sorption sites, and oxalate could also decrease sorption through dissolving clay minerals. Oxalate and HA could also facilitate As(V) desorption from the soil. Both sorption and desorption kinetics were two stage processes. Sorption kinetics conducted from 0.2-840 h showed that As(V) sorption increased with increasing residence time. Sorption equilibrium was retarded and the maximum sorption decreased in the presence of oxalate or HA. Phosphate-induced desorption kinetics conducted on the soil with 24 h and 840 h of sorption equilibrium time showed a significant effect of equilibrium time on As(V) desorption. The presence of oxalate or HA during the sorption process resulted in more As(V) desorption. Due to the degradation of oxalate, soil treated with oxalate and with a sorption equilibrium time of 840 h showed no significant difference in desorption kinetics from untreated soil.
