Characterization of pesticide sorption and degradation in macropore linings and soil horizons of Thatuna silt loam

Characterization of pesticide sorption and degradation in macropore linings and soil horizons of Thatuna silt loam

Journal of Environmental Quality 25(2): 227-235

The authors describe the characterization of soils from the surface A horizons, argillic Bt horizons, albic E horizons, and surface linings of macropores in the argillic horizons (Bt-M) of a Thatuna silt loam for their chemical, physical, and microbiological effects on adsorption, desorption, and mineralization of 2,4-D, carbofuran, and metribuzin. Distinct differences in the physical, chemical, and microbiological characteristics of the soil materials show that macropore linings in the argillic Bt horizon have a large resistance to desorb, a large potential to adsorb, and a large potential to mineralize pesticides. Results indicate that the adsorption potential of Bt-M soil material was comparable to that in A horizon soil, but that it had greater desorption partition coefficients than any other horizon.
