“…Simultaneously, various crop yields such as wheat (Triticum L.) (Mackowiak et al, 2001;Tahir et al, 2011) and corn (Zea mays) (Sharif et al, 2002) were enhanced with HA amendments. The water treatment residuals (WTR) were tested for reduction in (i) contamination of P in sandy and other soils (Ahmad et al, 2012;Ippolito et al, 2011;Miller et al, 2011;O'Connor et al, 2005;O'Rourke et al, 2012;Oladeji et al, 2008;Oladeji et al, 2009;Oliver et al, 2011;Ulen et al, 2012) and (ii) heavy metals (Fan et al, 2011;Mahmoud, 2011). However, except for few occasions (Hsu and Hseu, 2011;Mahdy et al, 2009;Oladeji et al, 2009;Park et al, 2010;Titshall and Hughes, 2009), they were rarely used as soil amendment to test for its ability to alter soil physical properties.…”

While biochar research has progressed, there is relatively little field-scale data over time, which constrains our understandings of biochar's "true" effects on soil quality and our ability to make appropriate recommendations to users, especially in comparison to other amendments. Thus, this study compares 2 successive years' field-scale soil data with biochar and other amendments added to a scalped silty clay loam soil at an application rate of 0.5%. None of the amendments significantly affected any of the measured soil physicochemical properties and greenhouse gas emissions even after 1.5 years of field aging. However, some of the measured soil properties were significantly changed after the second year compared with those of the first year. On temporal scale, soil electrical conductivity and penetration resistance significantly increased under most treated soils, and soil available water capacity significantly increased only under biochar. Although no differences in soil properties were detected, there was a trend toward higher corn dry grain and biomass yields under biochar compared with those of the control. Biochar was able to reduce N 2 O emissions from soil, only in the first year, whereas gaseous emissions were not different from control in the rest of the experiment. Thus, the findings of this study suggest that the improvements in soil fertility due to biochar amendment were not because of changes in most of the observed physical properties of the soil, but some other effects (changes in microbial community or nutrient additions) may have controlled the crop yield. In addition, these data demonstrate that selected amendment application rate of 0.5% (wt/wt) was not sufficient to cause significant changes in most observed physical properties beyond 1.5 years of field aging, suggesting additional research using higher rate of application.

“…Transforming DP in manures into PP by adding amendments either directly to manures or to soils is a management practice that has shown great potential for reducing DP leaching (Moore et al 1994;Miller et al 2011;Chardon et al 2012). Chemically speaking, an ideal amendment for manures would rely on a mechanism that (1) showed rapid removal of DP and (2) provided for long-term fixation (an irreversible process) under potential environmental conditions.…”

The effect of rare earth elements on phosphorus leaching in intact soil columns

Phosphorus (P) has been linked to eutrophication in surface waters because it is a limiting nutrient for algal growth, and recent studies have shown that P transport through subsurface flow is of growing concern. In this study we amended dairy and poultry manures with lanthanum (La) and ytterbium (Yb) chlorides to assess the efficacy of using rare earth element (REE) chloride amendments in reducing P leaching through intact soil columns and to determine the major pathways of applied P leaching. Significant reductions in dissolved P (DP; 56% to 64%), particulate P (PP; 22% to 36%), and total P (TP; 41% to 51%) in leachate were seen when dairy manure was amended with REE-chlorides, but no significant reductions in these P fractions were seen in amended poultry litter. Differences in P leaching losses between the two REE-amended manures were likely due to better mixing and dissolution of the REE-chlorides and better precipitation of an insoluble particulate REE-phosphate salt in the liquid manures prior to being applied. Very little vertical transport of REEs was observed in soil leachate over repeated events. Elevated concentrations of REEs along soil macropores at depths greater than 15 cm (5.9 in) suggest the importance of this pathway. However, due to the extremely low concentrations of REEs found at depth and the much higher values of soil P, the ability to "label" the manures with REEs to track P through macropores in the soil was only suggestive and by no means conclusive. Results point to the efficacy of REE-chlorides in lowering P solubility in liquid manures but limited potential in tracking subsurface transport pathways of applied manure P in soils.Key words: dairy manure-leaching-lysimeters-phosphorus-poultry litter-rare earth elements Once relegated as a marginal pathway of agricultural phosphorus (P) loss, leaching of P through soils has increasingly been associated with some of the world's most prominent examples of eutrophication (Sharpley et al. 1994). From Lake Erie, to the Chesapeake Bay, to the Baltic Sea, P leaching through the profile of agricultural soils fertilized with either mineral or manure sources of P has been tied to surface water P loadings. An increase in the enrichment of ground waters with P has been attributed to surface applications of P in agriculture (Holman et al. 2008;Domagalski et al. 2011). Increasingly, demand has grown for techniques that elucidate the mechanisms of subsurface agricultural P losses (Djodjic et al. 2002) and opportunities for controlling these losses .It is widely recognized that subsurface P transfers occur through macropore pathways in which P in leachate bypasses sorption sites within the matrix of a soil (Djodjic et al. 2002; Sørensen and Jensen 2013). While leaching of dissolved P has been the overwhelming focus of many studies, a consistent observation is that substantial fractions of particulate P can be leached. In soils with artificial drainage (e.g., tile drainage), observations of turbid drainage discharge are common (Frey et al. 201...

“…Permeable reactive barriers (PRBs) are also listed as an active barrier system [19], permeable reactive interceptors [20], a structure lime drainage system [8] or permeable drainage filters [21]. This method has been developed over the past decade and is used to treat groundwater and subsurface runoff from inorganic constituents such as P [22,23], ammonium [23], and heavy metals [24]. The main advantage of PRB is in situ treatment of contaminated groundwater which significantly reduces the treatment costs [25].…”

“…Some attempts have previously been made to apply RMs into PRBs as a method to increase P removal efficiency in agricultural areas. Some studies have been based on simple batch tests [22,23,30], laboratory scale experiments [20] and even full-scale working system applications [31][32][33].…”

This paper aims to examine the potential of permeable reactive barriers (PRBs) as an in-situ removal approach for phosphate polluted agricultural runoff. Four different reactive materials (RMs) of: autoclaved aerated concrete (AAC), Polonite®, zeolite and limestone were tested. The study was conducted as a column experiment with a sandy loam soil type charging underlying RM layers with phosphorus (P) and a soil column without RM as a reference. The experiment was carried out over 90 days. During this time the P-PO4 load from the reference column equaled 6.393 mg and corresponds to 3.87 kg/ha. Tested RMs are characterized by high P-PO4 retention equaling 99, 98, 88 and 65% for Polonite®, AAC, zeolite and limestone, respectively. At common annual P loss rates of 1 kg/ha from intensively used agricultural soils, the PRB volume ranged from 48 to 67 m3 would reduce the load between 65 and 99% for the RMs tested in this study.
