Description :
This study evaluates the influences of biochar made from the waste wood of white lead trees on the physicochemical and biological properties of long-term cultivated, acidic Ultisol. The AA. used 3 application rates of the biochar with the same incubation time. A simulated rainfall event was performed to estimate soil loss for all treatments at the end of the incubation time. Experimental results indicate that applying biochar improved the physicochemical and biological properties of the highly weathered soils. A 5% application rate of biochar is considered as suitable for highly weathered soil because this application rate efficiently improves soil physicochemical properties and reduces soil loss.
