Adsorption of prometryn and metolachlor by selected soil organic matter fractions


Soil Science 136(2): 94-101
Adsorption of prometryn and metolachlor by selected soil organic matter fractions
The adsorption of prometryn and metolachlor by different fractions of soil organic matter, including humic substances (humic and fulvic acids), humin, and nonoxidizable soil organic matter was studied. As a measure for adsorption evaluation, a distribution coefficient (Kdfom), calculated per unit of organic matter in each fraction was used. Humic substances showed high affinity for both herbicides. Humin fractions adsorbed significant amounts of prometryn, but not metolachlor.
