Coal and Its By-products

The aim of the present experiment was to evaluate the possibility of agricultural recycling of industrial waste, which has Pb and is rich in Fe, Zn, Ca. Chrysanthemum Rage (Dendranthema grandiflora Tzevelev) variety was cultivated in a greenhouse, in a commercial substrate where was added 8 doses of residue: 0.0; 0.38; 0.75; 1.50; 3.0; 6.0; 9.0 and 12.0g.L-1 of substrate. After 12 weeks, the plants were collected and the levels of Fe, Zn and Pb were analyzed in the substrate and on the plant tissues. Symptoms of Zn toxicity were observed, which were confirmed in the plant tissues analysis. The high Zn mobility and concentration in the industrial waste suggests its utilization as a source of Zn. The lower increase in Fe level is due to its lower availability to plants in culture conditions. Symptoms of Pb toxicity were not verified
