Bubble in a drop: Soil herbicide extraction

Date: Aug 11, 2014

Author: Steve Down

The distributions of two common herbicides in agricultural soils from spraying to crop harvesting have been followed using a recently developed extraction procedure in which an air bubble is trapped in a microdroplet of solvent to improve the efficiency.
