Orphaned or abandoned sulphide tailing disposal sites pose significant environmental hazards, including eolian dispersion, water erosion, acid mine drainage, and heavy metal mobility. Phytostabilization, an eco-friendly strategy, entails the use of alkaline amendments alongside non-native plant species capable of thriving in environments with high concentrations of heavy metals. A greenhouse experiment was conducted to assess the effect of a commercial cement which contained 46.3% sand, applied alone or combined w...

Repeated application of phosphorus (P) fert ilizer in soils, in excess of crop removal rates, may increase the concentration of P in soil solution and conse quently the transfer of soluble P to streams. Excess P in natura l aquatic systems can promote eutrophication of lakes and rivers. The application of calcareous sorbent in the adsorptive removal of P from soil solution could be a suitable technique. The objective of the experiment is to evaluate the sorption of P in a marginal coarse-textured soil (pH 5.5) ame...
