Abstract

A study was carried out to investigate the effect of biochar produced from the pyrolysis of poultry litter feedstock in some of the physical properties of a Yellow Red Argisol eutrophic typical (Ultisol), located in the municipality Lagoa Seca, State of Paraiba, Brazil, that is, granulometric analysis,  bulk density, porosity and available water capacity. Six doses of biochar (0; 10; 15; 20; 25 and 30 ton ha-1) were incubated into an Ultisol samples during 60 days. All assays were carried out in duplicate. After the incubation period, the soil samples were analyzed in relation to physical properties. The results  of  this  study  confirmed  that  the  biochar prepared  from  the  poultry  litter improved these properties, that is,  modified the granulometric analysis, led to a decrease in bulk density, an increase in total pore volume as well as an increase in water content mainly in matric potential 0.5065 MPa. The biochar dose, 30 ton ha-1 was better in soil density and porosity; in the water retention the best biochar dose was 15 ton ha-1; however, as the biochar effects on the physical properties were very small, it suggests to investigate larger amounts of this material in the application of the soils.
