Field evaluation of passive capillary samplers in monitoring the leaching of agrochemicals

Brandi-Dohrn, Florian M. (1993-11-17)

Soil solution samplers have certain inadequacies that limit their range of possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the soil pore-water via a fiber glass wick, have shown promis ...
Nitrogen scavenging : using cover crops to reduce nitrate leaching in western Oregon

Oregon State University. Extension Service; Sattell, Robert; Dick, Richard; Hemphill, Delbert D.; Selker, John S.; Brandi-Dohrn, Florian M.; Minchew, Hudson; Hess, Marlo; Sandeno, Joan; Kaufman, Susan M. (Corvallis, Or. : Extension Service, Oregon State University, 1999-10)

Willamette Valley field trials have shown that properly managed cover crops can reduce the amount of nitrate (NO3-)
Suction cup sampler bias in leaching characterization of an undisturbed field soil

Brandi-Dohrn, Florian M.; Dick, Richard P.; Hess, Mario; Selker, John S. (American Geophysical Union, 1996-05)

An accurate assessment of leaching losses in the vadose zone requires measurement of both solute and water flux to compute flux concentrations (C[subscript F]). Leachate collected at a depth of 1.2 m in 32 passive capill ...
