Abstract: To achieve satisfactory results with vermiculture, it is important to know how many times to rinse cattle manure to eliminate salts. Treatments under evaluation were 0, 1, 2, 3, 4, 5, 6 or 7 rinses in a tap water: manure ratio of 1 : 1 (v/v). Electrical Conductivity (EC), Biomass of Worms (BW) and Number of Cocoons (NC) were evaluated. The EC ranged from 2.57 to 0.5 dS·m⁻¹ for T0 and T4. The lowest BW (569.33 ± 68.8 mg) and NC (0 cocoon/week) were observed with T0. The highest BW (1218.8 ± 45.28 mg) and NC (3.35 ± 1.05 cocoons/week) were recorded for T5 and T7.
