Phosphate adsorption in Virginia Piedmont ultisols under long-term phosphorus applications


, : Phosphate adsorption in Virginia Piedmont ultisols under long-term phosphorus applications. Tropical Agricultural Research 9: 261-275

Phosphorus (P) adsorption is a determinant in agricultural production and environmental quality. Phosphorus adsorption behaviour was studied with the Langmuir and two-site Langmuir models in two soil series that received P applications for over three decades, namely, Davidson clay loam (clayey, kaolinitic, thermic, Rhodic Paleudults), and Tatum silt loam (clayey, mixed, thermic, Typic Hapludults) selected for study from Virginia Piedmont soils in the eastern USA.

Modelling faults from seismic data for a 3D depth model is a difficult task because of the multiple sources of uncertainty. The uncertainty may be attributed to migration velocities, picking of faults and organization of the fault network in 3D. F...
