Abstract:
: Biochar application to agricultural soil is a new management strategy for its potential role in soil
quality improvements. The aim of this study was to evaluate the effects of biochar derived from coffee husk
and corn cob produced at 350 and 500°C pyrolysis temperature on soil quality characteristics. The produced
biochars were applied at rates of 0, 5, 10, 15t ha and mixed with acidic soil then incubated in laboratory for 1
three months at ambient temperature. The treatments were arranged in a completely randomized design with
three replications. Results indicated a significant increase in soil pH, OM, OC, TN, available P, CEC and
basic cations when compared with control. The highest values were recorded when CHB500 applied at a rate
of 15 t ha . In summary, the results of this study highlight biochars improved the quality of soil, with benefit 1
to agriculture
