Functionalized charcoal (CHox) incorporated into urea is known for its ability to reduce NH3 volatilization and increase agronomic efficiency. However, it is important to optimize the functionalization process and to elucidate its relationship with the physicochemical properties of CHox for N supply. Thus, charcoal obtained from eucalyptus wood was...

High copper (Cu) and zinc (Zn) contents in soil can cause phytotoxicity to plants and contaminate surface and groundwater, with negative effects on agriculture and the environment. Functionalized charcoal (OCh) has high cation exchange capacity (CEC) and the ability to adsorb Cu and Zn and control their availability in the soil and water. An adsorp...

Volatilization losses reduce the efficiency of surface-applied urea for crop N uptake, and can be controlled using urease inhibitors to retard hydrolysis or by the presence of other amendments that enhance retention of NH4+ formed by urea hydrolysis. A greenhouse study was conducted to evaluate the effectiveness of oxidized charcoal (OCh; 150 g kg−...

... However, it can be controlled by retarding hydrolysis using urease inhibitors or enhancing NH 4 + retention formed by urea hydrolysis using amendments with high specific surface area and CEC. This approach does not only enhance NH 4 + retention but it also improves soil buffering capacity to reduce in pH [125]. This strategy was adopted by Paiva et al. [126] to coat fertiliser granules with oxidised charcoal as a fertiliser amendment because during hydrolysis, N fertilisers such as urea must be in the microsite contact with the oxidised charcoal to maximise efficacy. ...
