Wind and Spraying – Practical Wind Limits and Smart Field Windows
Wind is the most common cause of interrupted or poor spraying. Too much wind leads to drift and poor coverage; too little wind can cause inversion risk. Agdir anchors wind data per field and highlights operational windows that make planning concrete: which hours are safe, which are marginal, and in what order the fields should be treated. With clear wind limits, checklists, and automatic alerts, spraying becomes safer, faster, and more efficient.
Wind in Agdir – from uncertainty to safe spraying windows
Agdir visualizes wind speed and direction on a timeline per field and translates this into green (safe) and yellow (marginal) windows. Combined with temperature and precipitation data, it provides a practical assessment of when spraying is both responsible and effective. The result: fewer wasted trips, less chemical use, and better efficacy per treatment.
Practical wind limits – guidelines for fieldwork
Basic rule
Avoid spraying above X m/s, depending on nozzle type, pressure, and product (adjust to local regulations and practice).
Marginal windows
Short “pockets” of calm wind can be used early morning or late evening if distance to sensitive edges is maintained.
Inversion risk
Very low wind and falling temperature can create poor spray distribution. Prioritize early morning with stable air instead.
Field edges and neighbors
Include safety distances in your checklist and plan spraying order to match sheltered or open edges with the right wind directions.
How to use Agdir for sequencing and prioritization
1. Field-specific wind profiles – take Field A before B when the curve suggests it
View wind curves for each field and sort order based on green windows. A small field with ideal conditions from 05:30–06:30 can be more efficient to spray before a larger one with marginal wind in the evening.
2. Alerts when wind windows open or close
Let Agdir notify you and your team: “Green spraying window – North Field 18:30–20:00.” Add a short note in the task. Everyone gets the same information – no confusion.
3. Journal + inventory = documented compliance
When the spraying task is completed, date/time and weather context are automatically logged – and product use is deducted from inventory. This ensures easy reporting for audits and learning for next season.
Practical tips – less drift, more effect
· Plan nozzle type and pressure in templates/checklists – reduce uncertainty and improvisation in the field.
· Use a “border protocol”: treat sensitive edges in sheltered or open areas during the calmest minutes of the window.
· Prioritize cooler minutes in early morning or late evening for better absorption and lower drift.
· Split the task if needed: treat high-risk zones now, the rest in the next safe window.
Summary
Wind doesn’t have to be a gamble. With field-specific wind windows, clear limits, and structured checklists, spraying becomes safe, efficient, and verifiable. Activate wind profiles per field, set alerts for green windows, and plan your sequence by wind direction – reducing drift and errors while improving results.
