How to read this page
Transparent by design
Every indicator separates what it represents, why it matters, the evidence, possible implications, limitations and actions to consider. Missing information is never scored as favourable.
Satellites do not measure soil pH, nitrogen, phosphorus, potassium or overall soil health. Those require local tests.
Vegetation performance
- What it represents
- NDVI: how green and dense the crop canopy looks from space.
- Why it matters
- Shows crop vigor through the season and how it varies between months.
- Evidence
- Peak 0.74 in Jun; lowest 0.21 in Dec.
- Potential implications
- A normal seasonal curve. A weak or early-falling peak would suggest stress.
- Limitations
- Greenness is not yield and does not measure nutrients. One season cannot be tied to a rotation choice.
- Actions to consider
- Compare with the same months in earlier seasons and walk the field where values dip.
Water availability and stress
- What it represents
- Soil moisture (e.g. SMAP-type products) and irrigation access.
- Why it matters
- Low moisture in the growing period limits crop growth.
- Evidence
- Soil moisture reaches its lowest value of 0.11 m³/m³ in Aug. Irrigation: sprinkler.
- Potential implications
- Irrigation can buffer the summer dip; water-hungry crops need planning.
- Limitations
- Satellite soil moisture is coarse and reflects the top soil layer only.
- Actions to consider
- Check moisture on the ground before sowing summer crops.
Temperature and heat
- What it represents
- Land surface temperature (e.g. ECOSTRESS-type products).
- Why it matters
- Heat during flowering and grain fill reduces crop performance.
- Evidence
- Surface temperature peaks at 34 °C in Jul.
- Potential implications
- Heat-sensitive crops (e.g. canola, potato) carry more risk here.
- Limitations
- Surface temperature differs from air temperature.
- Actions to consider
- Consider heat-tolerant crops or earlier sowing dates.
Rainfall patterns
- What it represents
- Monthly precipitation (e.g. GPM IMERG-type products).
- Why it matters
- Determines how much water crops get without irrigation.
- Evidence
- Total 437 mm; driest month Jul (8 mm), wettest month Nov (55 mm).
- Potential implications
- Rain is low in Jul, Aug; plan irrigation or low-water crops for that window.
- Limitations
- Gridded rainfall can differ from rain at the field.
- Actions to consider
- Keep a simple rain gauge log to cross-check.
Season timing
- What it represents
- Your chosen sowing month and the crop sowing windows.
- Why it matters
- A good rotation still fails if a crop is planted outside its practical window.
- Evidence
- Sowing month: April; season preference: Any. Matching crops: April: Barley, Lentil, Canola, Sunflower, Maize, Potato.
- Potential implications
- Use the Best seasons page to compare the full sowing and growing calendar.
- Limitations
- Sowing windows are illustrative and vary by variety, altitude and local frost dates.
- Actions to consider
- Confirm dates with local extension guidance and a field trial.
Crop rotation diversity
- What it represents
- How many crop families appear in the field history.
- Why it matters
- Varied families help break pest and disease cycles.
- Evidence
- 1 crop family across 3 recorded seasons.
- Potential implications
- Low diversity: the history is dominated by one family.
- Limitations
- A short history gives a weak picture.
- Actions to consider
- Consider adding a legume or broadleaf crop to the plan.
Soil properties (local tests)
- What it represents
- Your own soil test results and local notes.
- Why it matters
- Satellites cannot measure pH, nitrogen, phosphorus, potassium or full soil health.
- Evidence
- pH: No data available; organic matter: No data available; local notes: No data available.
- Potential implications
- Without tests, recommendations rely on soil type and crop traits only.
- Limitations
- Missing values are never treated as favorable.
- Actions to consider
- Take a soil sample and enter pH, organic matter and local observations in Farm setup.
