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

Creator:

Brandi-Dohrn, Florian M.

Abstract:

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 promising results in preliminary experiments in regard to collection efficiency of water and of bromide tracers. The objectives of...

Long-term fertilizer input influences total and bioavailable metal in agricultural soils and crops

Creator:

Pérez, Angela L.

Abstract:

Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...
