  abstract = {{N}umerous studies have been conducted worldwide and more specifically in {B}razil assessing the consequences of biochar amendments on the soil properties and on the agronomical production. {T}he present study aimed to evaluate the effects of biochar of coffee residues on the physicochemical characteristics of an {E}ntisol and water use efficiency of maize ({Z}ea mays). {T}wo types of biochar were produced with both coffee ground ({CG}) and coffee husk ({CH}) and their physicochemical properties were characterized. {A} greenhouse pot experiment, quantifying the growth of maize, with different rates of biochar amendments and fertilizing procedures was conducted in a completely randomized design. {T}reatments consisted in four replications of (i) control (native soil), (ii) synthetic fertilization and (iii) organic fertilization with cow manure, and (iv) the two types of biochar in four doses (4, 8, 12 and 16 {M}g ha− 1). {S}pecific surface area ({SSA}) of {CH} was significantly higher than {CG} biochar but both types of biochar had higher {SSA} than soil. {N}utrient and water retention properties of soil and maize growth were significantly improved with increasing biochar doses. {T}he water use efficiency was 50% higher for the treatment with the highest dose of biochar. {T}his is a significant found considering the potential of growing maize on a sandy soil in a dry regions of {B}razil. {N}utrient use efficiency as well as the {C} content in {E}ntisol were largely improved by the use of biochar. {D}etermination of {SSA} was a quick and robust method to anticipate the benefits of biochar on water retention of soil.},
