  2. Liming increases yield and reduces grain cadmium concentration in rice paddies: a meta-analysis

    • Plant and Soil

    • Abstract


      Background and aims

      In China and several other rice growing countries, lime application is a common practice to alleviate soil acidification in rice paddies. Liming may also reduce the concentration of the common toxin Cadmium (Cd) in rice plants. We evaluated to what extent lime application affects rice yield and grain Cd concentration.

  13. Heavy metals accumulation and translocation in native plants grown on tailing dumps and human health risk

    • Plant and Soil

    • The heavy metal concentration in plant tissues of Ranunculus ficaria, Plantago major, Taraxacum officinale, and Achillea millefolium, frequently consumed or used in traditional medicine, collected from one of radioactive area of Romania, not been previously reported by any research group. The content of Cr, Mn, Ni, Cu, Zn, Cd, Pb were determined by ICP-MS.

  14. Exotic grass litter modulates seasonal pulse dynamics of CO 2 and N 2 O, but not NO, in Mediterranean-type coastal sage scrub at the wildland-urban interface

    • Plant and Soil

    • Abstract


      Aims

      Mediterranean shrublands adjacent to urbanization experience nitrogen deposition and exotic grass invasions which likely have downstream consequences for carbon and nitrogen emissions from soils. We tested a hypothesis that soil wetting produces trace gas pulses modified by seasonal wetting history, grass litter availability, and cover type in these systems.
