Agricultural Machinery, Tools and Practical Field Operations
What this domain tests
Domain 9 is the practical-operations domain: tractor and implement safety, correct machine setting and calibration, tool hygiene between plants, and the maintenance routines that keep an organic holding compliant (no contamination from conventional inputs, no spilled oil, no burnt plastics).
Core rules and concepts
- Tractor safety: ROPS frame or cab with seatbelt, guards on PTO and belts, hitch only to the drawbar, engine off and key out before servicing, no passengers, stable ballast on slopes; terraced Cypriot fields demand low gears and care on headlands.
- Organic contamination: a sprayer previously used with a prohibited product must be triple-rinsed and preferably kept solely for permitted products; keep a separate sprayer where possible.
- Tool hygiene: disinfect secateurs, saws and grafting knives between trees (70 % alcohol or a permitted disinfectant) against grapevine trunk diseases and Xylella-risk material; clean tyres and implements moving between fields.
- Calibration: sprayers and fertiliser spreaders must be checked at the start of each season and after nozzle changes.
- Residue management: chip or compost prunings instead of burning (fire risk, organic matter loss, and burnt plastic residues); collect and recycle plastic mulch, drippers, bags and containers.
- Maintenance: oil, filters and batteries go to a licensed collector, never to a field corner or a dry riverbed.
Worked example
A boom sprayer has four nozzles, each delivering 1.2 L/min, on a 2 m boom; spraying speed is 5 km/h. Reasoning: total output = 4 × 1.2 = 4.8 L/min. Application rate = (output × 600) ÷ (speed × swath) = (4.8 × 600) ÷ (5 × 2) = 2,880 ÷ 10 = 288 L/ha. If the label allowance is 300 g copper per hectare and the product contains 50 % copper, you need 600 g of product per hectare; at 288 L/ha the tank concentration is 600 ÷ 288 ≈ 2.1 g/L. Now check the annual copper cap: 288 L/ha × 4 applications is fine in volume, but the copper total must stay under 4 kg/ha/year.
Traps that cost marks
- Calibrating with water but spraying a denser suspension without re-checking nozzle wear.
- Using one sprayer for both conventional and permitted products without documented triple rinsing.
- Working under a raised implement or loader without mechanical support.
- Burning prunings in summer, which risks fire and destroys carbon that belongs in the compost heap.
Harvesting, Post-Harvest Handling, Storage and Marketing
What this domain tests
Domain 10 covers the value chain: judging maturity correctly, harvesting without damage, removing field heat, storing under the right conditions, and selling the product legally - including the label and the PDO/PGI dimension that matters for Cypriot products such as Halloumi.
Core rules and concepts
- Maturity indices: Brix and acid ratio for grapes and citrus, oil content and colour change for olives, dry matter for potatoes, firmness and background colour for tomatoes; harvest before over-ripeness, not after.
- Harvest hygiene: clean, stackable, disinfected crates; no produce on the ground; harvest workers with clean hands and no open wounds; respect pre-harvest intervals for copper and sulphur.
- Field heat: move produce to shade within an hour, then pre-cool (forced-air or hydrocooling) where the crop allows; roughly 10 °C of cooling can halve respiration and double shelf life.
- Storage conditions: tomato 12–13 °C (chilling injury below 10 °C), potato 4–8 °C in the dark with ventilation and sprout control by cold and air - CIPC is prohibited; onion and garlic cured and dry-stored; olive oil in stainless steel, dark, 14–18 °C, low oxygen, extracted within 24–48 h of picking at under 27 °C paste temperature, with free acidity kept below 0.8 % for extra virgin.
- Traceability and labelling: lot identification, harvest and input records, EU organic logo, control body code, PDO/PGI names used only by authorised users.
Worked example
A grower delivers 5 t of olives three days after picking, with fruit-fly punctures and fruit warmed in sacks. Reasoning: fly-damaged and crushed fruit raises free fatty acids and peroxide values through lipase and oxidation; a three-day delay at ambient temperature can lift free acidity from about 0.3 % to over 0.8 %, pushing the oil out of the extra-virgin class and cutting the price. The correct operational sequence is: harvest at the right ripeness, keep crates shallow and ventilated, deliver to the mill within 24 hours, mill below 27 °C, store in inert stainless steel under nitrogen, and record the lot so the oil can be traced back to the grove.
Traps that cost marks
- Storing tomatoes with chilling-sensitive crops at 4 °C and calling the resulting pitting a disease.
- Mixing organic and conventional lots in one store or one press.
- Quoting a "sprout inhibitor" for organic potatoes - most are prohibited; use cold, darkness and ventilation.
- Forgetting that the organic label plus the control body code must appear on the final pack.
Occupational Health and Safety in Agricultural Work
What this domain tests
Domain 11 tests whether you can identify hazards in real Cypriot field conditions - summer heat, tractors on slopes, copper and sulphur sprays, livestock handling, ladders in olives - and state the control that actually removes or reduces the risk. Expect short hazard-and-control questions and PPE identification.
Core rules and concepts
- Risk assessment first, PPE last. Eliminate, substitute, engineer (guards, ROPS, ventilation), then administrate (rotation of tasks, signage), then protect.
- PPE for sprays: nitrile gloves, coveralls, goggles/face shield, and an A1P2 respirator for dusts and mists such as copper and sulphur; boots; re-entry intervals observed; no eating, drinking or smoking during work; wash hands and change clothes afterwards.
- Chemical store: locked, ventilated, labelled, on a spill tray, with safety data sheets available, away from feed and seed; empty containers triple-rinsed and returned to collection points.
- Machinery: ROPS and seatbelt, guarded PTO, implement lowered and locked before maintenance, no work under a raised loader.
- Heat stress: in Cypriot summers, schedule heavy work for early morning, provide shade, cool water and electrolytes, acclimatise new workers, and recognise early symptoms (headache, cramps, confusion) before heat stroke.
- Working at height: inspected ladders, three points of contact, no chainsaw above shoulder height, chainsaw trousers and helmet with visor.
- Livestock: zoonoses (brucellosis, Q fever, leptospirosis) - gloves and hygiene at lambing and handling; safe cattle/ram handling; crush and race where needed.
- Noise above 85 dB requires hearing protection; dust requires masks; first-aid kit and emergency number 112 displayed; accidents recorded.
Worked example
A worker must apply Bordeaux mixture to vines in August with a knapsack sprayer. Reasoning: the hazard is not just toxicity but heat and drift. Controls: spray before 10:00 with wind under 3 Beaufort and away from bystanders and watercourses; wear nitrile gloves, coveralls, goggles and an A1P2 respirator; check the copper budget before mixing; carry drinking water and work in pairs; observe the re-entry interval before anyone enters the rows; wash equipment and hands at the end, and record the application. If the temperature passes the agreed threshold, stop - heat illness is the more likely injury than poisoning.
Traps that cost marks
- Equating "organic product" with "harmless": copper and sulphur are irritants requiring full PPE.
- Wearing a dust mask for solvent vapours, or the wrong cartridge for the hazard.
- Ignoring heat stress and dehydration as "not a real safety issue".
- Leaving the tractor engine running or the loader raised during maintenance.
