  abstract = {{B}iochar has been used to reuse the agro-industrial wastes and improve soil quality. {S}everal studies have been carried out to show the impact of biochar on physical and chemical soil attributes. {H}owever, there are still gaps regarding the effects on as microbial biomass and enzymatic activities that are important to determine sensitive indicators to evaluate changes in management practices. {T}he objective of this study was to assess the effect of two biochars on the chemical, microbial biomass carbon, and the enzymatic activities in an {E}ntisol cultivated with bean. {W}e evaluate two types of coffee biochar: ground and husks, four doses (4, 8, 12, and 16 {M}g ha(-1)) and control. {A}ll treatments received organic fertilization with cow manure. {H}usks biochar increase the soil p{H}, {C}a, and {K}, also contributing to the reduction of toxic aluminum contents and raising the concentrations of {P} labile. {T}he treatments that received ground biochar showed higher soil organic carbon, microbial biomass, beta-glucosidase, and fluorescein diacetate. {B}iochar produced from coffee residues increased sandy soil quality. {W}e showed the first report on the beneficial impact of coffee biochar on enzymatic and microbiological quality of sandy soil cultivated with the bean.},
