Interpretive Summary:

Technical Abstract: It is important to evaluate agricultural management practices which influence SOM dynamics and pesticide behavior in SE Coastal Plain soils since the soils are inherently sandy and low in OM. The objectives of our study are: 1) to investigate the microbial properties of soils under long-term conservation and conventional tillage, and 2) to establish relationships of these properties with atrazine sorption and soil physico-chemical properties. Composite soil samples were collected from two tillage plots that were under 20 yrs of conservation and conventional tillage in Darlington, SC. The soils were characterized for specific physical, chemical, and microbiological properties. Populations of atrazine-degraders and atrazine sorption coefficients were also determined. The effects of tillage on these chemical and microbial properties and the atrazine degradation potential will be discussed.
