Irrigation planning made easy. Choose crop and soil, enter ETo/rain, then get water volume, timing, and a clear schedule, with history and pro analytics.
Irrigation Calculator Pro helps farmers, gardeners, and agriculture pros plan watering with confidence, even without internet. Pick a crop, set your soil, enter ETo and rainfall, and the app calculates how much water you need, how often to irrigate, and the next irrigation date. Simple inputs, accurate results.
Why it’s different
• Works fully offline: no accounts, no APIs, no syncing required.
• Scientifically grounded: uses FAO-standard formulas and effective rainfall.
Key features
• Smart Calculator: Supports 58+ crops with verified Kc values, 6 soil types (AWC-based), crop-specific root depth, and manual ETo/rainfall. Instantly see water volume, frequency, and timing.
• Units your way: Full metric/imperial support (mm/in, L/gal).
• Scheduling made clear: Get the next irrigation date and alerts when soil deficit reaches the MAD threshold.
• History & Records: Save calculations by field/crop; search and review past runs.
Pro tools
• Analytics Dashboard: Track water use trends, compare crop efficiency, view soil water deficits, and estimate costs.
• Custom Crops: Add your own crops with custom Kc and root depth (with validation and helpful ranges).
• Seasonal Planning: Guidance for spring, summer, autumn, and winter to save water while protecting yield.
How it works
• Select crop and soil.
• Enter field size, ETo, and recent rainfall.
• Get required water volume, irrigation frequency, and next date, ready to act.
Designed for
• Professional farmers, consultants, and landscapers who need quick, reliable decisions.
• Serious home gardeners and students learning irrigation science.
