Main menu
What each menu option does
After setup, tap an option in the WhatsApp menu (open View options for longer lists). arandu sends a short answer first and a heatmap image when available. Typing the number still works if you prefer.
Sample reports
Report types and example heatmaps
Each report combines a short WhatsApp explanation with a field image. Use the color legend to read the map, and the trend chart below it to see recent movement. Menus 1–5 use growth-stage thresholds and a 4-week trend—not a 5-year historical benchmark. The image date tells you how recent the satellite or radar data is.
How to read a report message
Most satellite reports follow the same structure so you can scan them quickly in WhatsApp.
- Headline: the colored status icon and short title tell you the urgency first.
- Current State: what the latest image shows now, including crop condition and growth stage when available.
- 4-week trend: whether the field is improving, stable, or declining over the last four weeks.
- Action: one or two practical next steps, such as scouting a weak zone on the map or scheduling irrigation.
- Yield Outlook (menu 8) and Season review (menu 9) compare the season to past years on your field. Menus 1–5 do not use a 5-year historical benchmark.
- Date: the satellite or radar image date, so you know how fresh the observation is.
Nitrogen Status
Highlights chlorophyll and nutrient signals. The sample shows optimal levels across the field, with no immediate action needed.
Water Status
Checks whether plants are holding moisture. In the sample, the field is well-hydrated for its growth stage, with no dry-spell alert active.
Flood Detection
Uses radar imagery to detect standing water even when clouds are present. The sample shows no significant flooding, only about 0.02 hectares of possible standing water.
Erosion Risk
Estimates soil loss risk from slope, rain, cover, and bare soil exposure. The sample shows low erosion risk with protected soil cover.
Extra tools
Photos, weather, and settings
These tools follow the same habit as the satellite menu: tap an option, follow the next prompt, then read the structured answer. Each block below walks through the steps with sample chat bubbles.
Photo analysis
Turn a photo in the furrow into observation, possible causes, scouting ideas, and a quick severity cue.
1
Open photo analysis
When you see the analysis menu, tap Analyze Photo. arandu switches to photo mode and explains how to attach your picture.
📸 Analyze Photo
📷 Send a photo of your crop and a question.
Example: Send photo + “What's wrong with this plant?”
Example: Send photo + “What's wrong with this plant?”
2
Send the image plus one concrete question
Use good light, hold the phone steady, and add text such as What is wrong with these leaves? Close-ups beat distant silhouettes when you need symptom detail.
3
Read the four-part reply
The message summarizes Observation, Possible diagnosis, Recommended actions, and Severity so you can match it with boots-on-the-ground scouting.
- Observation: arandu identifies the crop, visible weeds, leaf damage, yellowing, necrosis, or disease symptoms.
- Possible diagnosis: the sample soybean looks generally healthy, with weed competition and minor insect feeding.
- Recommended actions: scout weeds and insects, check defoliation thresholds, and keep watching for diseases such as rust or leaf spot.
- Severity: arandu summarizes urgency, for example Low when crop health is good and the main risk is weed management.
Weather forecast
One message bundles outlook, rain totals, and farm-planning hints.
1
Request the five-day outlook
Tap Weather Forecast in the analysis menu. arandu answers with a title line, a short conditions summary, and supporting detail when the weather service returns data.
🌤️ Weather Forecast
🌤️ Weather Forecast (5 days)
Dry conditions: 0mm total rain expected over the next 5 days.
- Daily outlook: min/max temperatures and sun, cloud, or rain icons for each day.
- Spray windows: highlights acceptable periods and warns when wind is too high for application.
- Irrigation: tells you when to irrigate now if a dry period is expected.
- Farm planning: use the forecast to plan spraying, irrigation, scouting, and field access.
2
Plan spraying, irrigation, and field access
Scan for spray-safe windows, irrigation timing, wind and temperature alerts, then combine that with what you can see from the field gate.
What to scan first
Start with the headline outlook and total rain, then read spray and irrigation sections before loading equipment.
Settings
Settings stay as the last menu option so the first nine stay focused on agronomy.
1
Open the settings drawer
Tap Change Settings at the end of the analysis menu. That opens field, crop, language, and privacy tools in one place.
