How does the plant get the copper?

Posted on Oct 20, 2012 in

The Copper in MicroKote is absorbed by the plant roots and held by the root tip. The plant actually “mines” the copper out of the coating. Because the copper is mined the longevity of the coating is determined by the root density adjacent to the container wall. When the plant root tip make contact with MicroKote the root tip dissolves a tiny amount of the coating & copper. The copper is absorbed, root elongation stops, apical dominance is broken and lateral root growth is initiated.
