Project Summary:
The inactivation of herbicides in soil is
largely attributed to rapid decomposition of
thesubstrate. However for many herbicide, inactivation is
not necessarily due to decomposition but to
reversible sorption of the compound to soil solids.
Hence repeated applications of a particular herbicide,
may lead to a buildup of the active compound in the
sorbed state in soil. This investigation examines
how temperature and repeated application of
glyphosate affects the sorbed state of this compound in soil.
