چکیده
to evaluate the impact of the application of thehran municipal solid waste compost (mswc) on zinc and copper concentrations in the soil under maize (zea mays. l.) cultivation, a factorial experiment in base randomized complete block design (rcbd) with two different amounts of municipal solid waste compost (zero, 30.15 and 60 t ha-1) and time (compost applied once or twice) was performed with three replications. the results showed that mswc has a significant effect on reducing of ph and increasing of cation exchange capacity and organic carbon (p≤0.01). mswc significantly increased soil total and dtpa extractable zn and cu. (p≤0.01). the highest amount of dtpa extractable zinc and copper respectively observed 10.82 and 9.29 mg kg-1, in the 60 t ha-1 second year of treatment, as compared with control for zn 97.94 and copper 110.02 percent was increased. results showed that mswc has a significant effect on increasing zn and cu concentration in roots and shoots (p≤0.01). the highest amount of zinc and copper uptake was observed in the 60 t ha-1 second year of treatment, as compared with control respectively 92.36 and 70.26 percent for zinc and 73.87 and 118.62 percent for copper in root and shoot increased. mswc for both zinc and copper caused an increase in bioavailable factor, although this was more pronounced for copper. there were significant positive correlation between total and dtpa-extractable zn and cu and concentrations of these elements in root and shoot.
