Getting Started

  1. Open the Brix Tracker from the Tools page or bookmark it on your phone for quick field access.
  2. On first use, enter your Farm Name, Assessor Name and Email. These are saved automatically for next time.
  3. The app works offline — you can record data without signal and it will sync when you are back online.

Recording a Measurement

  1. Select the Block / Field and Crop Type you are assessing.
  2. Tap Get GPS to capture your location (optional but recommended for mapping).
  3. Enter the Number of Trees Sampled — this is the count of trees you measured to get your averages.
  4. Fill in the Brix measurements below. EC and pH are optional but recommended.
  5. Optionally add Weather, Recent Treatments and Notes.
  6. Tap Save Record. A results summary appears confirming your data.

How to Take Each Measurement

MetricUnitHow to Measure
Brix%Select fully expanded, mature leaves from the current season’s growth. Crush or press the leaf to extract sap and place a drop on the refractometer prism. Close the cover plate and read the Brix scale at the boundary line. Average readings across sampled trees.
ECmS/cmUsing the same leaf sap, apply a drop to a portable EC meter (or use a digital refractometer with EC function). Record the electrical conductivity reading. Higher EC generally indicates greater mineral density in the sap.
pH0–14Place a drop of leaf sap onto pH test strips or into a portable pH meter. Healthy leaf sap typically ranges between 6.2 and 6.8. Readings outside this range may indicate nutritional imbalances.
Tip: Consistency matters more than precision. Always sample the same trees, same leaf position (4th or 5th fully expanded leaf from the tip), and at the same time of day so your trend data is comparable. Early morning readings (before 10am) tend to be most stable.

Understanding Your Readings

Brix RangeInterpretation
0 – 6Poor — low sugar and mineral content. Plant is likely under significant nutritional or environmental stress.
6 – 10Below average — room for improvement through nutrition and biology.
10 – 14Good — healthy range for most orchard crops. Adequate photosynthesis and mineral uptake.
14 – 18Very good — strong plant health. Often correlated with improved pest and disease resistance.
18+Excellent — exceptional mineral density. Typically seen in well-managed biological systems.
Why track Brix? Brix is a quick, inexpensive way to measure the sugar and dissolved mineral content of plant sap. Rising Brix readings over a season indicate that your nutrition programme and soil biology are working. Falling readings signal a need to investigate and adjust.

Syncing & the Data Tab

  1. When online, records sync automatically. You can also tap Sync Now in the header bar.
  2. Switch to the Data tab to view, filter and manage all saved records.
  3. The Charts tab plots Brix, EC and pH trends over time — filter by block and crop to compare seasons.

Email, Print & Export

  1. Email Report — sends a formatted HTML report to your email address via the server. A copy is also sent to Succession Soils.
  2. Print — opens a landscape-formatted print view showing all records in a table. Use your browser’s print or “Save as PDF” option.
  3. Export CSV — downloads all records as a CSV file you can open in Excel or Google Sheets for further analysis.
Offline workflow: Record data in the field without signal. When you return to Wi-Fi, open the app — it will sync automatically. Then use Email, Print or Export from the results view or Data tab.
