Irrigation Scheduling
Workflows
Irrigation scheduling is a decision workflow, not one sensor value or calendar date. It brings together crop stage and condition, soil-water evidence, weather observations and estimates, field variability, irrigation-system capacity and performance, water availability, and local operating authority.

HOW TO READ THIS PAGE
Visual explanationA diagram or operating scene makes the relationship visible.
Structured modelA flow, comparison, capability set, or boundary map organizes the idea.
Guided explanationOriginal prose connects the concept to its operating context.
01 / Overview
Schedule the review,
not just the machine.
University of Minnesota Extension resources on evapotranspiration-based scheduling and irrigation provide a public foundation for viewing scheduling as a recurring evidence cycle. The workflow must remain local because crop, soil, weather, system, water, regulation, and management objectives differ.
World Farm Tech maps the information roles and evidence handoffs. It does not tell a farmer when to irrigate, how much water to apply, or which estimation method is appropriate for a particular field.

constrain, verify.
01OBSERVE / 01Assemble current evidenceCrop and growth context, field observations, soil-water evidence, weather observations, forecasts where appropriate, and data quality

04 / Practice
Keep the schedule
connected to evidence.
Qualify weather and sensor inputs
Record observation sources, forecast status, gaps, timing, spatial relevance, maintenance, and method assumptions.
Use measured system context
Include system capacity, distribution evidence, downtime, maintenance, and water-delivery constraints rather than assuming ideal performance.
Review after operation
Compare the operation record and field response with the assumptions, then document changes for the next decision cycle.
05 / Boundaries
A workflow is
not a water prescription.
No timing, depth, depletion, or threshold is recommended.Use current qualified local agronomic, water, regulatory, and system guidance for field decisions.
Models and sensors are evidence inputs.Each has spatial, temporal, maintenance, method, and uncertainty limits that must remain visible.
Scheduling does not prove delivery or response.System operation, distribution, crop response, and later outcomes require separate observation.

A scheduling workflow can provide authorized timing or target intent while automation retains independent equipment, sensing, interlock, delivery, exception, and operator checks.

Scheduling records can supply planned timing, target, field, zone, assumptions, and authorization context to water accounting, while measured delivery and reconciliation remain separate.
