Research – Chlorophyll


Leaf Chlorophyll Content – University of Portsmouth

  • University of Portsmouth research confirmed that root drenching increased tomato leaf chlorophyll content by 20-50%.
  • A second experiment – using a cotyledon bioassay technique on cucumbers confirmed a 300% improvement in chlorophyll levels six weeks after a root drench.
  • This data is confirmed by a range of independent researchers throughout Europe, using chlorophyll meter tests in crops during periods of active in-season growth.
