This study assesses the amount and nature of surfactants present in mineral soils. Soil samples were collected at 0-5 cm and 5-15 cm sampling depth following two different crop rotations. Crop rotation included a two-year corn\soybean, compared to a four-year corn\soybean\spring wheat\field pea. Natural surfactants were extracted from soil using a combination of organic and aqueous solvents and they were characterized by solid state NMR and IR spectroscopy. Data suggests that the type of treatment applied to the soils affects the content and nature of surface active compounds in soils.
