2-Inch Disc Filter Sizing: Why Connection Diameter Does Not Determine Capacity

Two filters with identical connections can produce different operating limits. Use a worked pressure worksheet and a one-unit-offline check to compare complete assemblies.

Effective Rainfall for Irrigation: Decide How Much Rain Reaches the Root Zone

A field worksheet separates gauge rainfall from retained root-zone water, tests three storm cases and shows how to revise an irrigation account without double counting.

IoT Irrigation Connectivity: Compare LoRaWAN, Cellular, and Farm Wi-Fi

Choose farm connectivity using tested coverage, command timing, power and service costs, with explicit payload, battery and on-time delivery calculations.

Agricultural Sprinkler Uniformity: Design and Run a Catch-Can Test

An original catch-can map shows how to calculate sprinkler CU and low-quarter DU, distinguish collector opening from represented field area, and interpret uneven application.

Technical2026-08-28

Irrigation Lateral Line Length: Check Friction, Elevation, and End Pressure

A segment-by-segment example shows how outlet withdrawals and terrain change lateral pressure, including a case where end pressure passes and midpoint pressure fails.

Technical2026-08-27

Orchard Irrigation Expansion: Add Emitters as Young Trees Establish

Use root-zone observations to expand young-tree irrigation in stages, then check outlet flow, zone limits and event volume with a clearly stated example.

Technical2026-08-26

Drip Irrigation for Corn: Match Lateral Layout to Rows and Field Operations

A corn lateral-layout decision record with original row and tubing calculations, machinery checks and separate wetting and establishment evidence.

Technical2026-08-25

Remote Irrigation Alarm Design: Choose Thresholds Farmers Can Act On

A practical alarm worksheet links state-specific flow limits, pressure, valid measurements, persistence and operator response, with a worked timing trace.

Technical2026-08-24

Fertigation Tank Dilution: Why Nutrient Concentration Changes During Injection

A worked dilution curve separates tank concentration, instantaneous mainline concentration and total nutrient dose, with explicit mixing and flow assumptions.

Technical2026-08-23

Sand Media Filter Backwashing: Verify Flow, Pressure, and Bed Expansion

A backwash acceptance worksheet with area-based flow calculations, pressure comparisons, an expansion example and a separate media-carryover sample check.

Technical2026-08-22

PVC Pipe Sizes for Irrigation: Nominal Size, Outside Diameter, and Pressure Class

A primary-source dimension table, three hypothetical quotations and a complete-assembly pressure check show how to specify compatible irrigation PVC pipe and fittings.

Technical2026-08-21

Evapotranspiration for Irrigation: Convert Reference ET into a Field Water Budget

A three-day example reconciles crop ET, rainfall and root-zone depletion before converting retained irrigation depth into metered volume and runtime.

Technical2026-08-20

Greenhouse Irrigation Zoning: Separate Crop Stage, Container Size, and Substrate

A greenhouse zoning matrix with an original three-group delivery calculation, capacity and timing checks, nutrient-path boundaries and acceptance records.

Pressure-Compensating Drip Tape: Read the Operating-Pressure Range Correctly

A real manufacturer-sheet review and an original pressure-window calculation show why compensation range, tape limits and field pressure variation must be checked together.
