Interpretive Summary:

Technical Abstract: Commercially available biochar exhibits limited phosphorus (P) adsorption capacity due to the presence of inherent P and oxygen containing negative surface functional groups which impacts their use in controlling P losses from agricultural runoff. This presentation will examine the effectiveness of biochar optimization for controlling phosphorus release dynamics in agricultural systems. The outcome of the study revealed that biochar modification could produce an efficient sorbent material for P. Further study is required to evaluate the cost effectiveness of biochar modification and potential use of modified biochar in agricultural lands to reduce environmental P loss risk during runoff events.
