“…For example, in China, poplar (Populus deltoides × Populus nigra) grown in Cd-contaminated purple soil and alluvial soil accumulate 542 and 577 g·Cd per plant and Cd concentration in poplar was increased with the increase of Cd concentration in both soils [24]. Also, similar decreases in N and P originated from contaminated sources have previously been reported following cultivation of poplar and willow [25]: poplar and willow grown in lysimeters are able to retain 66% and 82% respectively for total N and 80% and 99% respectively for total P, following the application of landfill leachate containing 378 kg·N·ha −1 ·year −1 and 19 kg·P·ha −1 ·year −1 .

Phytoremediation is a promising technology to remediate carcass burial sites where deep soil layers are contaminated with nitrogen (N), phosphorus (P) and other potential contaminants by leachate. The current study was conducted to examine the remedial efficiency of two different woody plants, poplar (Populus euramericana) and willow (Salix alba), by employing the deep-planting technique for the enhanced removal of N and P for the soil affected by leachate. For this, pot trials to assess N and P removal efficiency of poplar and willow in liquid manure-applied soil, and pilot-scale column experiments to evaluate the suitability of the deep-planting technique for the enhanced phytoremediation of deep soil layer were conducted. The results of this study showed that poplar and willow removed N and P from soils effectively while surviving under deep-planting conditions. Notably, compared to the surface planted roots, the roots of the deep-planted poplar and willow could transfer significant amounts of N and P leachate from the deep soil layer to the rhizosphere, from where it can be absorbed by the plants. For the first time, the use of poplar or willow plants are recommended by employing the deep-planting technique for the successful remediation of carcass burial sites.

“…Willows are known to have several characteristics that make them ideal plant species for phytoremediation application, including easy propagation and cultivation, large biomass, fast growth, deep root systems, a high transpiration rate, tolerance to hypoxic conditions, and high metal accumulation capability [15][16]. S. babylonica is a species of willow that has adapted to waterfront and wet environment with a great potential for restoration of soil environments or contaminated water, and is one of the most widely distributed and commonly cultivated willow species in China [17].…”
