Nothing here is saved. Leave the app and this field is gone. Pomarium GAIA keeps every block and collects it night after night — years of canopy, weather, bloom dates and yield forecasts. See what an account adds →
Read one of your Pomarium blocks here. It stays in GAIA — nothing is copied into AGER, and nothing you draw here is added to your orchard.
Takes about ten seconds. You only do it once.
Each reading is a different way of looking at the same satellite image. You do not need all five — start with NDVI, which is what the free app shows. The other four come with AGER Saved.
The workhorse. It rises as the canopy fills and falls when trees are stressed, losing leaves, or thin. A mature orchard in full leaf usually sits around 0.7–0.9; young or sparse plantings read lower simply because there is less canopy, which is not a fault.
The mirror image of NDVI. High early in the season and falling as the canopy closes. A rise in mid-season means canopy you had is no longer there.
In a dense canopy NDVI flattens out — it cannot tell a good canopy from a very good one. These two still can. NDRE picks up nitrogen and stress earlier; CCCI asks whether the leaf area you have is actually green and working, rather than how much of it there is.
Behaves like NDVI but keeps its resolution where the canopy is dense and NDVI has saturated.
Look at the map, not the graph. A healthy block is close to one colour. Patches, stripes or a wedge reading lower than the rest mean something local — and local problems have a cause you can go and find.
Use 4 weeks or 8 weeks. If the whole field moved together, that is usually weather, irrigation, or the season moving on. If one part dropped while the rest held, that is a fault, and it is worth walking.
Water problems follow the pipe, so they show up as straight lines and blocks rather than soft patches. A dry wedge usually points to a valve or pressure; a dry strip along a row to a blocked line; scattered dry spots to emitters. Compare with 4 weeks ago to tell a new fault from one that has been there all season.
Last year compares the same field on the same date a year ago. Below last year at the same point in the season means a slower canopy — check water, nutrition and crop load. The shape of the curve usually tells you more than any single number.
Before you act on a low reading: check the date and the % clear under the map. Thin cloud reads as a dip that is not real. One low point is not a problem — a trend is. And the satellite tells you where to walk, not what is wrong; confirm it on the ground before you change anything.
Agricultural Geospatial Evaluation & Remote-sensing — ager is Latin for a field.
Stand in the block, trace it, and AGER fetches the most recent cloud-free Sentinel-2 image — the same satellite data the full Pomarium platform runs on — and reads the canopy for you.
Keep it to hand: add AGER to your home screen and it opens full-screen, like any other app — the button below shows how, in three steps.
One field at a time, up to 150 ha (371 acres). Nothing is stored — no account, no history. GAIA is the version that remembers.
