Compute emitter discharge, application rate, and wetted percentage for a sample lateral layout, showing each step

Build a one-page formula sheet covering depth, volume, application rate, and irrigation interval, and solve five practice problems using it

Design a complete drip layout for a 1-hectare orchard block: choose emitter spacing and discharge, size laterals, submains, and main, and state pipe diameters with justification

Select and size a filter (screen/sand/disc) and a fertigation tank for the designed system, with reasoning tied to water quality assumptions

Prepare a bill of quantities and a simple cost estimate for the designed drip system

List at least eight commissioning and installation checks (flushing, pressure testing, emitter uniformity test) and explain why each matters

Compare drip, micro-sprinkler, and mini-sprinkler systems on wetted pattern, application rate, clogging risk, energy need, and suitable crops, and match each to five given field scenarios

Design a sprinkler layout for a sample field: select nozzle size and spacing, compute application rate and precipitation uniformity, and check against soil intake rate

Calculate sprinkler system head and pump duty requirements including elevation, friction, and operating pressure

Identify causes of poor uniformity in sprinkler systems (wind, spacing, pressure variation) and state a corrective measure for each

Explain layout considerations for both surface and subsurface drip, including depth of placement and salinity concerns

Match pump type (centrifugal, submersible, monoblock) to given water source and head/flow requirements, and read a pump performance curve to select an operating point

Diagnose ten written fault scenarios (low pressure, uneven discharge, emitter clogging, filter backwash failure, pump cavitation) and state the likely cause, a test to confirm it, and the repair step

Describe a preventive maintenance schedule for filters, emitters, valves, and pumps across a season, with frequency and action for each item

Explain fertigation safety and sequencing steps, including injection placement, flushing, and backflow prevention

Outline the main components of an automation setup (controller, solenoid valves, sensors) and describe one simple programming scenario

Interpret a water quality test report (pH, EC, hardness, iron, suspended solids) and state its implications for emitter clogging and treatment choice

Explain how irrigation scheduling and leaching fraction address salinity buildup, and compute a leaching requirement for a sample case

List environmental safeguards for micro-irrigation (preventing runoff, safe chemical handling, disposal of flushed water) and describe one practice for each

Prepare a costing sheet for a small drip system covering capital cost, annual operating cost, and simple payback against conventional irrigation

Summarize (in your own words, without quoting scheme documents) the categories of government support typically available for micro-irrigation and the documents a farmer usually needs to apply

Perform a written emitter uniformity evaluation from given flow measurements and decide whether the system needs cleaning, replacement, or redesign

Revisit weak areas from weeks 1-6 by re-solving missed numerical problems and re-explaining concepts aloud

Explain how to record and present project work: measurements, observations, calculations, and conclusions in a simple report format

Practice explaining one technical concept to a non-technical customer in under two minutes

Complete two full-length timed practice tests under exam conditions and score each by domain

Review every missed question and write a corrected explanation for each, identifying the underlying concept gap

Re-derive the ten most important formulas from memory and check them against your formula sheet

Recite the key facts for each domain (component functions, maintenance intervals, safety controls, scheme categories) in a rapid self-quiz

Finalize a one-page pre-exam summary sheet limited to facts you have personally verified
