📅 Irrigation Scheduling Calculator

Calculate irrigation frequency and depth based on soil type and crop water use.

Soil Available Water (mm/m)Available water capacity from soil test

Management Allowed Depletion (%)Irrigation trigger point

Root Depth (cm)Active root zone depth

Crop ET (mm/day)Daily crop water use

📐 How It Works

Total Available = AWC × (Root Depth ÷ 100) | Depletion = Total Available × (MAD ÷ 100) | Days = Depletion ÷ ET
