Figure 1

Example of the horizontal and vertical spatial distribution of pesticide degradation as affected by agricultural practices and soil structure. This sketch presents the distribution of MCPA degraders in a soil treated with MCPA and where MCPA is mainly transported through subsoil via wormholes, as observed by rensen and Aamand (Badawi et al., 2013a,b). Surface soil, which receives MCPA application, hosts a relatively abundant and spatially homogeneous degrading population, while degraders in the subsoil cluster around preferential flow paths.
