From an agronomic perspective, the spreading of manure (sometimes containing antibiotics) onto
agricultural fields is beneficial to the soil as a renewable source of
fertilizer by increasing organic matter and providing nutrient inputs for
crops. However, the use of antibiotics can be excessive, resulting in manures
containing residual antibiotics contaminating soils and waterways. Thus, there
is a need to improve existing or develop new management practices to minimize
the losses of antibiotics from manure entering waterways and groundwater.
Biochar is a carbon-rich material produced from the oxygen-free pyrolysis of
biomass. Generally, biochars have high surface area and sorb organic compounds
and trace metals; thus, it is reasonable to hypothesize that biochars sorb
antibiotics. The main goal of this research was to investigate if incorporated
biochar to soil facilitates the transport of antibiotics under simulated
rainstorm events. The specific objectives were to investigate the losses of
surface-applied antibiotics to soils with different (1) application rates of
biochar and rainfall intensities, and (2) if the losses were antibiotic
type-dependent. <br>
