Pressure-Reducing Irrigation Valves: Minimum Flow and Stable Regulation

A duty matrix checks low-flow and pressure limits before valve approval, with guidance for zero demand, unstable readings and field commissioning.

Technical2026-08-17

Irrigation Flow Meter Pulses: Convert Counts into Litres, Gallons, and Alarms

A pulse-to-volume worksheet with reciprocal factors, timed flow calculations, sparse-pulse alarms, counter continuity and an independent volume check.

Technical2026-08-16

Irrigation Pump Curves: Find the Operating Point as Zones Change

Calculate pump and system-curve intersections as irrigation zones change, then check branch delivery, efficiency, source level and the limits of speed scaling.

Technical2026-08-15

Irrigation Automation Interlocks: Stop the Pump When No Valve Is Open

A state-transition worksheet for irrigation pump automation, with physical delivery checks, a sector-overlap calculation and functional acceptance tests.

Technical2026-08-14

Irrigation Water Testing: Build a Filtration Specification from Lab Results

Translate water-quality laboratory reports into a treatment specification, with sampling questions, an incoming-solids calculation and an acceptance worksheet.

Technical2026-08-13

Fertigation Stock Solutions: Check Solubility and Mixing Compatibility

A stock-solution worksheet connecting product specifications, water analysis, storage temperature and two separate compatibility checks, with an illustrative concentration calculation.

Technical2026-08-12

Drip Irrigation Pressure Budget: Account for Every Loss from Pump to Emitter

A worked pressure-head ledger with named test points, regulator inlet requirements, emitter limits and a loaded-filter sensitivity check.

Technical2026-08-11

Drip Irrigation Uniformity: Run a Field Catch Test and Interpret the Results

A practical emitter sampling worksheet with an original 36-reading example, flow conversions, low-quarter DU calculation and pressure-based diagnostic checks.

Technical2026-08-10

Irrigation Controller Wiring: Build a Station and Common-Wire Test Map

Create a station-to-valve wiring map with labelled common branches, reproducible de-energized resistance checks and a record of which physical valve each station operates.

Technical2026-08-09

Irrigation Solenoid Valve Troubleshooting: Electrical Fault or Hydraulic Fault?

Trace a failed irrigation zone from its command to the coil and water path, using two diagnostic tables, a worked resistance example and a return-to-service record.

Technical2026-08-08

Remote Moisture Monitoring: Where to Place Soil Sensors in a Drip-Irrigated Field

Map representative soil zones, root depths and drip emitter wetting patterns, then commission each remote moisture monitoring station with a documented irrigation event.

Technical2026-08-07

Irrigation Filter Pressure Loss: Set a Backwash Trigger from Measurements

Use paired pressure readings, measured flow and a clean-filter baseline to build a backwash setting record that protects downstream irrigation pressure.

Technical2026-08-06

Fertigation System Calculations: From Nutrient Target to Injection Rate

Convert an approved nutrient target into fertilizer mass, stock volume and injection rate, then verify delivery with a timed calibration and operating record.
