Want to measure pasture quality in real time — not guess it from colour and growth?
In this video, Ben Christensen (GreenMate Agriculture) shows how to do BRIX testing properly, and why most people get misleading results.

BRIX testing gives you a fast snapshot of plant sap sugars and an extra clue many miss: the definition/fuzziness of the line, which can indicate more complex dissolved solids and feed value. We cover how to sample pasture without bias, how to zone a paddock, how many grabs you actually need, and the simple calibration step that protects your data.
This is practical, farmer-to-farmer measurement that helps you track:
pasture nutrition changes through the season
paddock-to-paddock differences
the impact of grazing decisions and fertility programs
stress effects (heat, drought, cloud cover, time of day)
You’ll see the full process using accessible gear: a cheap refractometer, water for calibration, and a basic garlic press to extract sap — plus the common traps that ruin readings (dew, gateways, troughs, “fertility patches”, and sampling at the wrong time).
For more context on why this method matters and how it fits into real farm decision-making, I’ve also written about BRIX testing on my site.
Chapters are below so you can jump straight to calibration, paddock zoning, sampling, or reading the line.
