The application of organic amendments into heavy metal contaminated soil is considered as an environmentally friendly technique to promote the potential of phytoremediation. A pot experiment was carried out to evaluate the effect of humic substances on growth, cadmium (Cd) accumulation and phytostabilization potential of the mining ecotype (ME) and the corresponding non-mining ecotype (NME) of Athyrium wardii (Hook.) grown in Cd-contaminated soils. The addition of the humic substances demonstrated great promotion for the growth and Cd uptake of ME. Both plant biomass and Cd concentration significantly increased with the increasing application of the humic substances up to 100 g kg(-1), beyond which no significant change of underground part biomass and Cd concentrations in underground part of A. wardii was observed. The maximum Cd concentration in underground part of ME was 180 mg kg(-1) when 150 g kg(-1) humic substances were applied. The ME showed greater Cd accumulation capability in underground part (0.47-0.68 mg plant(-1)) than that of NME (0.27-0.45 mg plant(-1)). Increasing bioaccumulation coefficient (BCF) values of A. wardii was observed with increasing application of the humic substances. The BCF values of ME were higher than those of NME. However, the use of the humic substances exhibited little impact on translocation factors (TFs) of ME, and the TF values of ME were less than NME. Furthermore, the application of the humic substances improved the remediation factors (RFs) of A. wardii. The RF values in underground part of ME ranging from 0.73 to 0.91 % were apparently higher than those of NME. These results indicated that the humic substances can be a potential candidate for enhancing the phytostabilization of A. wardii grown in Cd-contaminated soils.

“…Meeinkuirt et al indicated that high root biomass and great root length was one of the accepted criteria for plant materials suitable for phytostabilization. In addition, plants with a high capacity for biomass production are beneficial to pollutant removal . The root biomass of ME was observably greater than that of NME, which was much superior to stabilize Pb in the root zone.…”

Research ArticlePb Uptake and Phytostabilization Potential of the Mining Ecotype of Athyrium wardii (Hook.) Grown in Pb-Contaminated Soil Phytostabilization has been proposed as a cost-effective remediation strategy to immobilize metals in heavy metal polluted soils. A pot experiment was conducted to evaluate the Pb uptake characteristics and phytostabilization potential of the mining ecotype (ME) of Athyrium wardii and the corresponding non-mining ecotype (NME) when exposed to the Pb contaminated soils for 40 days. The ME was more tolerant to Pb than the NME when grown in Pb contaminated soil, and the ME demonstrated a greater Pb accumulation ability in roots (30.6-175.45 mg plant À1 ) than the NME (0.85-25.59 mg plant À1 ). The bioaccumulation coefficients of ME ranging from 52.02 to 83.16 were 3.24-8.89 times higher than those of the NME under Pb treatment, and the translocation factors of ME ranging from 0.022 to 0.079 were <1. The ME showed a higher capability in absorbing available Pb in soil than the NME. Furthermore, Pb remediation factors in roots of the ME were 6.93-15.35 times higher than those of the NME, and the plant effective number in roots of the ME ranging from 5.70 to 12.74 were lower than those of the NME. These results indicated that the ME showed a greater Pb uptake and phytostabilization potential than the NME, which enabled it as a worthy candidate for Pb phytostabilization.

“…2), occurred due to the high amount of P added to the soil, the form of P found in the SE and the soil management system. Manures have high concentrations of nutrients, including of P (Guo and Li 2012;Ye et al 2014), contained in manures in an inorganic form (Cassol et al 2001). This form is readily available to plants, and this is the predominant form of P accumulation in manure-fertilized soils (Chardon et al 2007;Adeli et al 2008;Gatiboni et al 2008;Lourenzi et al 2013).…”

Successive swine effluent applications can substantially increase the transfer of phosphorus (P) forms in runoff. The aim of this study was to evaluate P accumulation in the soil and transfer of P forms in surface runoff from a Hapludalf soil under no-tillage subjected to successive swine effluent applications. This research was carried out in the Agricultural Engineering Department of the Federal University of Santa Maria, Brazil, from 2004 to 2007, on a Typic Hapludalf soil. Swine effluent rates of 0, 20, 40, and 80 m3 ha(-1) were broadcast over the soil surface prior to sowing of different species in a crop rotation. Soil samples were collected in stratified layers, and the levels of available P were determined. Samples of water runoff from the soil surface were collected throughout the period, and the available, soluble, particulate, and total P were measured. Successive swine effluent applications led to increases in P availability, especially in the soil surface, and P migration through the soil profile. Transfer of P forms was closely associated with runoff, which is directly related to rainfall volume. Swine effluent applications also reduced surface runoff. These results show that in areas with successive swine effluent applications, practices that promote higher water infiltration into the soil are required, e.g., crop rotation and no-tillage system.
