The quality of poultry manure composts obtained from composting heaps were evaluated, in the following treatments: 1) without gypsum and turning; 2) without gypsum and with turning; 3) with gypsum and turning; 4) with gypsum and without turning. The quality of composts was evaluated with the Department of Agricultural (DA) standards established to the occurrence of eggs and grubs of helminthes, Salmonella sp, fecal and total coliforms, Cd, Cr, Ni, Pb, Se, C, N, humidity, C:N and C:CEC rations, and pH. The quality of composts from the turned heaps agrees with the DA standards, except the C content, which was lower. In the composts obtained from heaps with gypsum addition and without turner, the content of this element was higher than the minimum required but the values of N, eggs of helminthes, and water content did not meet the DA standards. The metal content of the composts was low, with the exception of Cd, but it was due to the high content of this metal in the manure used to make the gypsum heaps. This additive decreased the pH value of the composts and increased the N content of the no turned heaps. Considering all evaluated attributes, the best composts were obtained from the turned heaps.
