Start with an irrigation observation.
Build a record that makes water decisions easier to discuss and review.
General educational information, not a diagnosis or a farm-specific treatment plan. Conditions vary by climate, variety and growing system.
Look at the growing context
Water needs vary with crop, stage, soil and weather. A fixed schedule alone cannot describe those changing conditions.
Record what you can verify
Note the date, irrigation duration, growing area and soil or substrate observations. Include measured amounts when available and distinguish measurements from estimates.
Review with local context
Use these records when discussing irrigation with an agricultural specialist. The reference below covers vegetable production in Minnesota; local greenhouse and UAE conditions require adaptation.
