A paper-filter system to investigate the real micro-environment circuiting plant roots

The micro-environment circling the plant root is an interesting topic for many researchers. Until now there is not an approach to investigate the exact density of chemicals surrounding the plant roots. Here we use a simple paper filter system and gas chromatography to quantify the exact density of chemicals surrounding the plant roots. This can help solve a long-existing doubt about the ‘real micro-environment’ surrounding the plant roots.
