Abstract

Background and Objectives: Application of SEWAGE SLUDGE as a cheap and waste material is increasing for supporting plant essential elements especially in the soils of arid and semiarid regions. The results of various researches have shown that application of SEWAGE SLUDGE increased the content of ORGANIC CARBON (OC), N, P and K in soil and plant and the yield of grain and straw in WHEAT, barley and corn plants. The effect of sludge on the improvement of above cited attributes mostly depends on the origin (urban or industrial) and used rate of sludge and also plant type. Therefore, this study was conducted to investigate the effects of Ardabil municipal SEWAGE SLUDGE at the used rates on some MACRONUTRIENTS and heavy metal concentrations in soil and plant and also some agronomic traits of WHEAT.Materials and Methods: The examined soil and sludge were prepared from a bare land in Ardabil plain and waste-water refinery of Ardabil city, respectively. The pot study was carried out as a randomized complete block design with 5 treatments and 4 replications. Treatments were: zero (control), 30, 60, 120 and 180 tons of air-dry sludge/ha. Spring WHEAT was sown in pots (diameter 20 cm and height 25 cm) then the soils were incubated at the temperature of 22±4oC and moisture of 60 to 80 percent of field capacity for 100 days. The yield of grain and straw and also the concentration of N, P and K were determined in WHEAT components at the end of growth season. Also, the values of soil electrical conductivity (EC), OC, N, P, K, Pb, Cr, Ni and Cd were measured according to the standard methods.Results: The results showed that application of sludge at the rates of 30 to 180 tons/ha significantly increased OC (21.94 to 176 percent), total N (81 to 310.34 percent), extractable P (16.7 to 123 percent) and extractable K (5.34 to 117.8 percent) in the soil under growth of WHEAT. The concentration of N, P and K in grain increased significantly in 180 tons/ha treatment about 36.04, 112.34 and 86.64 percent compared with control, respectively. Sewage application increased grain yield and WHEAT growth indices such as shoot dry weight, height and grain weight and leaf area. The effect of sludge application rates on the concentration of Pb, Cr, Ni and Cd was not significant in soil.Conclusion: The best improving effect of sludge on soil and plant attributes was obtained for 120 and 180 tons/ha treatments and significant difference was not observed between these treatments. Therefore, with consideration of the high EC of used sludge, the 120 tons/ha treatment can be recommended as suitable application rate for improving chemical quality of the soil. Conducting field experiments is necessary for confirming the results of this study especially with different soils and plants.
