Abstract: Field trials were conducted to evaluate the effectiveness of municipal sludge organic fertilizer on the growth, yield, quality of potato and uptake of heavy metals by plant. The results indicated that, along with application of normal fertilizers, application of sludge organic fertilizer could significantly increase potato yield, commercial class and quality. The contents of Hg, As, Pb, Cd, Cr, Cu and Zn were below the national food and hygiene standard level.
