This study aimed to evaluate the effect of the application of biochar in soil physical properties. The experiment was arranged in a randomized block design with 6 treatments: 1-without biochar (control); 2-biochar coconut; 3-sludge biochar; 4-biochar coconut + sludge (1:1); 5sludge biochar + raw sludge (1:1); 6-biochar + coconut raw sludge (1:1). The amount of biochar was applied 30 t.ha -1 , with 4 repetitions, and a total of 24 plots. The plots consisted of crop lines with areas of 1.05 m 2

Biochar is produced in a furnace adapted based on the model developed by IBI (International Initiative biochar) and used as biomass residue of coconut production (dried coconut shells). The coconut shells were put in the oven internal chamber to the pyrolysis process. The plots consisted to sites with areas of 16 m 2 each, which was grown okra. Soil moisture was monitored using tensiometers installed at depths of 10 cm and spread in the experimental area. The parameter evaluated were soil moisture. The results showed that the moisture had little variation among the treatments.
