The study was carried out to examine the effects of soil conditioner application on the soil reclamation and growth response of Artemisia princeps and Helianthus annuus in the vicinity of heavy metal-contaminated abandoned zinc mine area. The efficiency of soil conditioners on soil reclamation was evaluated based on the degree of plant growth in the contaminated soils. The growth of A. princeps and H. annuus was promoted by the treatment of phosphorus and organic matters, and dolomite, respectively. Phosphorus increased the total chlorophyll content of A. princeps and H. annuus, while the plants treated with dolomite had 10 to 20% higher chlorophyll fluorescence. The results obtained in the present study could provide basic information about eco-engineering through soil reclamation.
