This study aimed to evaluate the speed of manure decomposition at different depths. Donkey, cow, goat, and sheep manure was used after stove drying at ± 65 °C. 20 g of each manure was wrapped in nylon bags and applied superficially or buried at 10.0 cm depth. Monthly, a nylon bag/plot was collected. The material was cleaned to evaluate decomposition, oven-dried and weighed to determine the loss percentage in relation to the initial weight. Decomposition was slow in the first thirty days when ± 95 % of the manures remained in the nylon bags. The manure decomposition rate was strongly influenced by rain in the experimental period. It was observed that donkey manure was more resistant to decomposition and the decomposition speed was higher in the manures applied 10.0 cm deep.
