and Poschenrieder, 2002 ; Yu et al., 2016 ). The concurrence of high Al (Al toxicity) and low P (P deficiency) has been widely investigated for many plant species ( Liao et al., 2006 ; Maejima et al., 2014 ; Zheng, 2010 ). Aluminum toxicity is

centrifuged for 15 min at 8000 g n and supernatants reserved. The process was repeated once for seeds and twice for skins, for a total of 4 and 9 mL of solvent, respectively. Bound phenols (those glycosylated to larger molecules or ligans) were extracted

independent transport systems. Whereas the hyperbolic phase at low external sugar concentration is believed to represent a high-affinity, membrane-bound, carrier-mediated component, the linear nonsaturable phase at higher concentrations has been suggested to

specially built airtight 180-L aluminum chambers were constructed for commodity storage. Fig. 1. Schematic design of the research-scale hypobaric system constructed according to Burg (2004) . Chambers were constructed from a 0.9-cm-thick aluminum

covered with aluminum foil with several small holes to prevent light from reaching the moss surface and yet allow for water evaporation. The cultural practices were similar to that of Expt. 1. Pots were fertilized or watered every 6 weeks as a result of

phosphate adsorbed to small particles of aluminum oxide (Al-P) and can be mixed into sand culture to maintain P levels at low concentrations (μmol levels) over an extended period of time ( Coltman et al., 1982 ; Elliott, 1989 ; Lynch et al., 1990 ). The

aluminum, iron, or calcium ( Brix et al. 2001 ; Hsieh and Davis 2005 ), and expanded shales ( Vohla et al. 2011 ) are incorporated. For example, Glaister et al. (2014) demonstrated excellent P removal capabilities of stormwater biofilter columns with a

incorporated before application of CB to soil. Previous laboratory studies indicated aluminum sulfate (Alum) incorporated in biologically derived biosolids at an Al:P molar ratio near one minimized WEP concentration ( Huang and Shenker, 2004 ). Alum effects on

highly acid soils of these beds, generally of pH between 4.0 and 5.0 ( DeMoranville, 2008a ), any free phosphate is readily bound to iron and aluminum. In standard soil tests, this bound P is often detected as available and yet cranberry samples taken
