Particulate transport of pesticides, heavy metals, and phosphate in soil is of interest when evaluating water contamination risk; however, researchers differ in their view of how and where the contaminated particles are mobilized. The main line of th

Desorption kinetics of chemical compounds can be important both for their mobility in soil and for the significance of particle-facilitated transport. We studied desorption of glyphosate [N-(phosphonomethyl)glycine] on mobilized particles from two so

Dye-tracer studies in the field using Brilliant Blue FCF as tracer were performed to investigate the effect of irrigation intensity and soil heterogeneity on preferential flow. In two fields, both level and newly tilled in terms of seed bed preparati

Because dissolved organic matter (DOM) plays an important role is terrestrial C-, N- and P-balances and transport of these three components to aquatic environments, there is a need to include it in models. This paper presents the concept of the newly
