Study context

One pond, recorded by Blueweight's technical team during routine use. With no untreated comparison pond, the change cannot be attributed to the product alone.

How it was measured

  • Depth measured with a graduated PVC pole at five central points of the pond.
  • Readings recorded by Blueweight R&D/technical staff during the 2023 crop.
  • Source: internal Ecofresh test report, pp. 11–15.

What this does not show

  • No untreated comparator pond.
  • Single pond; other management practices also influence sludge.
  • Internal observation — not independent, not peer reviewed.
