Abstract This study was undertaken to
study the effects of different amounts of kiln dust mixed with soil on the
seed germination, plant growth, leaf area and water content of Vicia faba
cv. Eresen. The reason for this was that cement kiln
dust generated as a by-product from the cement factories is rich in
potassium, sulfate and other compounds.
This product becomes a serious problem when it comes in contact with
water. The dust was collected from a cement factory located in Çanakkale. Various elements such as Al, Co, Mo, Ca, B, Cd, Cr, Cu, Fe, K, Mg, Mn, Na,
Ni, P, Pb, S, Se and Zn were determined both in
soil as well as kiln dust. Kiln dust was mixed with soil in pots (20 cm
diameter) to make seven different treatments varying from 15 to 105 g kiln
dust kg-1 of soil. The experiment lasted for 4 months. Seeds of V.
faba were sown in the pots filled with mixtures
of preanalysed kiln dust and soil. Germination was
high in the pots with a lower treatment of cement kiln dust. However, lower
germination rates were observed in the pots mixed with the highest and the
medium amounts of cement kiln dust. Plants growing in the soil including 15 g
kiln dust showed better performance in length as compared to control. Leaf
area increased with
increase in cement kiln dust content up to 60 g kiln dust kg-1
of soil, but declined after 75 g kg-1. Water content of leaves (mg
cm-2 leaf area) was found to be constantly decreasing with respect
to increasing cement kiln content in the pots. Differences between the
averages were evaluated by Tukey test and results
were found to be significant. Key
words Cement kiln dust, Vicia faba,
Plant growth, Air and soil pollution |
