“…The rinsing water was not analyzed for P content because this was a quick procedure of just a few seconds and we did not expect large amounts of P to be removed from the soil samples. Although no other study has sequentially extracted P from soils used in sorption studies, research on the sequential fractionation of animal manure has shown that a significant amount of P can be lost during the washing of the residue between extractants (Turner and Leytem 2004;He et al, 2009;Pagliari and Laboski 2012).…”

This study was developed to provide initial information on the chemical distribution of P into the different soil P pools after a soil sample underwent P sorption using 17 soil samples from the united States (13) and Brazil (4). During the sorption phase, soil samples were equilibrated with solutions containing increasing P concentrations (0-75 mg P l -1 ) following standard procedures. Following the sorption phase, the soil samples were allowed to air dry for 72 h and underwent a chemical fractionation (in water, anionic resin, 0.5M NahCo 3 , 0.1M Naoh, and 1.0M hCl). A wide range of sorption strength ranging from 0.043 to 0.289 l kg -1 and a maximum sorption ranging from 189 to 789 mg kg -1 were observed. More than 59% of the sorbed P was found in the water + resin fraction, which is considered the most labile pools where the binding energy is assumed to be low. In contrast, less than 25% of the sorbed P was found in the nonlabile pools where the binding energy is assumed to be the greatest. Although less than 25% of the sorbed P was found in the non-labile pools, the Naoh+hCl fraction contributed 2 to 61% of the overall sorption strength estimated for the soils studied. The results of this study suggest that sorption strength calculated from sorption studies are heavily skewed toward the nonlabile fraction, which was found to constitute a very small portion of the binding sites occupied during sorption studies.Abbreviations: b, the sorption maximum; ICP-OES, inductively coupled plasma optical emission spectroscopy; b f , sorption maximum determined using the sequential fractionation data; b i , sorption maximum estimated using the method of Nair et al.

W hen P is added to soils in the form of fertilizer, a series of reactions takes place, ranging from diffusion of P from the fertilizer granules into the soil solution, sorption of P into soil particles, and, with time, P precipitation (Hedley and McLaughlin, 2005). In the soil, inorganic P (P i ) will adsorb or precipitate by chemically binding with Al, Fe, or Ca (Lombi et al., 2006;Khatiwada et al., 2012;Eriksson et al., 2015). The solubility of phosphorus in soil is controlled by several factors, including how much P is originally adsorbed in the soil, how much P is precipitated in the soil, the soil pH, clay mineralogy, organic matter content, what types of minerals were formed during P precipitation, and the concentration of Ca, Al, Fe, and other cations in solution (Delgado and Torrent 2000;Violante and Pigna, 2002;Shigaki and Sharpley 2011;Weng et al., 2012;Eriksson et al., 2015;Gérard, 2016). McLaughlin et al. (2011) has shown that the amount of Ca...

“…2015;Schoumans et al 2014). Also phosphorus bound in organic matter may be released by hydrolysis by reducing the pH (Chen et al 2007;Pagliari and Laboski 2012 (Schoumans et al 2014). This leads to a relatively small volume of highly concentrated P-rich precipitates that can be easily exported or used as secondary resource for fertiliser P industries (Ehman et al 2017;VCM 2015).…”

Chemical phosphorus recovery from animal manure and digestate; Laboratory and pilot experiments.Wageningen, Wageningen Environmental Research, Report 2849. 114 pp.; 43 fig.; 37 tab.; 41 ref.Since a number of decades the Netherlands faces manure surpluses, because the amount of phosphate produced in animal manure is larger than the amount that can be applied on agricultural land according to the application limits. This surplus needs to be exported from the Dutch agricultural sector. The costs of manure export are however high, and therefore new, simple and cheap innovative techniques are needed to recover phosphate from fresh or digested manure (digestate). The relative small amount of concentrated recovered P can be transported more economically for use outside the Netherlands or can be utilized as secondary P resource for industries, e.g. for the production of fertiliser. We report laboratory and pilot experiments that were carried out in search for cheap and innovative techniques of phosphorus recovery. The main goal of the experiments was to reduce the P-content in pig slurry or digested pig slurry by 25% to 75%. If this goal can be reached with -recovery, in principle all manure including its valuable components (organic matter and other nutrients) can be applied sustainably on agricultural land in The Netherlands. The results show that both on laboratory scale and pilot scale 25-75% of P can be technically recovered with the so called 'acid-base approach'. From a sustainability point of view the impact is positives in terms of energy savings, CO 2 -savings, phosphorus savings and also nitrogen savings. The economical perspective is also positive but will strongly depend on the disposal prices of treated pig slurry with a reduced P content and its value as substitute for mineral N fertiliser and value in terms of organic soil improver on the manure market.Keywords: phosphate, manure, digestate, intensive livestock production, phosphate recovery, pig slurry, manure treatment, manure separation. • Acquisition, duplication and transmission of this publication is permitted with clear acknowledgement of the source.• Acquisition, duplication and transmission is not permitted for commercial purposes and/or monetary gain.• Acquisition, duplication and transmission is not permitted of any parts of this publication for which the copyrights clearly rest with other parties and/or are reserved. New innovative approaches are needed to close the phosphorus (P) cycle in The Netherlands because the agricultural sector currently produces about 25% more P, in the form of manure, than can be applied on land. One promising solution to deal with the surplus amount of P in manure is to recover the surplus of P in the form of a mineral P product for use as a P fertiliser (for export) or as a raw P feedstock for the P fertiliser industries. This idea for 'closing the manure P cycle in The Netherlands' has been circulating for a while, but was never thought well over until in 2013 a Public Private Partnership (PPP) was set up with t...

“…Total P concentrations vary largely among the different organic manures, depending on the livestock and livestock management. The P concentrations in cattle manure usually range from 4.5 to 14.2 and 2.8 to 15.0 g kg -1 P for the meat and milk production managements, respectively (Pagliari and Laboski, 2012).…”

Inorganic phosphorus (Pi) usually controls the P availability in tropical soils, but the contribution of organic P (Po) should not be neglected, mainly in systems with low P input or management systems that promote organic matter accumulation. The aims of this study were to evaluate the changes in the Po fractions over time in soil fertilized and not fertilized with cattle manure and to correlate Po forms with available P extracted by anion exchange resin. The experiment was carried out under field conditions, in a sandy-clay loam Haplustox. The experimental design was a 2 × 9 randomized complete block factorial design, in which the first factor was manure application (20 t ha -1 ) or absence, and the second the soil sampling times (3, 7, 14, 21, 28, 49, 70, 91, and 112 days) after manure incorporation. Labile, moderately labile and non-labile Po fractions were determined in the soil material of each sampling. Manure fertilization increased the Po levels in the moderately labile and non-labile fractions and the total organic P, but did not affect the Po fraction proportions in relation to total organic P. On average, 5.1 % of total Po was in the labile, 44.4 % in the moderately labile and 50.5 % in the non-labile fractions. Available P (resin P) was more affected by the manure soluble Pi rather than by the labile Po forms. The labile and non-labile Po fractions varied randomly with no defined trend in relation to the samplings; for this reason, the data did not fit any mathematical model.
