The floor soil ground is used in most of the Brazilian poultry farms due to the high cost of the construction of concreted floors. The presence of organic matter on the surface of the soil hinders its disinfection, due to the reduction of the antimicrobial action of disinfectants and the tests accomplished in vitro to verify the effectiveness of the disinfectants do not contemplate the adverse conditions found at poultry farms. Thus, the present work intended to determinate the volume of disinfectant solution required to be used on m² floor and the counting of total and fecal coliforms in floor soil ground. Presence of total and faecal coliforms was detected in the depth of 0.5cm with 1100NMP g-1 e 460NMP g-1, respective. The volume of disinfectant solution defined to saturate 1m² to 1cm of depth was of one liter.
