摘要

In pot experiments, 2-year-old (1 + 1) alder (Alnus glutinosa) and sycamore (Acer pseudoplatanus) trees were grown on mine waste mixed either ammonium nitrate, mineral phosphate, potassium sulfate, calcareous sand, a superexpanding polyacrylamide gel polymer, cake sewage sludge or diatomite. The most successful amendments with regard to tree growth and leaf chemistry effects were cake sludge and diatomite for alder and mineral phosphate, calcareous sand and cake sludge for sycamore. The least successful amendments were ammonium nitrate, potassium sulfate and calcareous sand for alder and ammonium nitrate for sycamore.
