Impact of percentage and particle size of sugarcane biochar on the sorption behavior of clomazone in Red Latosol
Abstract Biochar is a carbonaceous material that has excellent potential as a fertilizer and soil conditioner. However, there is a lack of information concerning the effects of the amount and particle size of this pyrogenic material on the soil sorption capacity. In this work, evaluation was made of...
