How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Which method uses channels between crop rows?

Answer: Furrow irrigation. Water flows in parallel grooves carved between planted rows.

Flashcard 2: Which method may require leveling of fields?

Answer: Flood irrigation. Flat fields ensure uniform water distribution across entire area.

Flashcard 3: Identify one advantage of drip irrigation.

Answer: Reduces water waste and evaporation. Delivers water precisely where needed, preventing losses.

Flashcard 4: What is the role of an irrigation controller?

Answer: Automates the timing and duration of watering. Electronic device that schedules irrigation based on programmed settings.

Flashcard 5: Identify a limitation of drip irrigation.

Answer: Can clog and requires maintenance. Small particles block emitters, disrupting water flow patterns.

Flashcard 6: Which irrigation method uses rotating sprinklers?

Answer: Center pivot irrigation. Automated rotating system that moves in circles around a central point.

Flashcard 7: Which method is best for sandy soils?

Answer: Drip irrigation. Sandy soils drain quickly, so precise application prevents waste.

Flashcard 8: Identify a limitation of drip irrigation.

Answer: Can clog and requires maintenance. Small particles block emitters, disrupting water flow patterns.

Flashcard 9: What is localized irrigation?

Answer: Water is applied directly to the plant base. Targets specific plant zones rather than entire field areas.

Flashcard 10: What is center pivot irrigation?

Answer: A sprinkler system that rotates around a central pivot. Automated system that covers circular areas efficiently.

Flashcard 11: What is flood irrigation?

Answer: A method that involves flooding fields with water. Simple but inefficient method, often used for rice cultivation.

Flashcard 12: What is drip irrigation?

Answer: A method where water drips slowly to plant roots. Delivers precise amounts directly to roots, minimizing waste.

Flashcard 13: Identify one cause of irrigation inefficiency.

Answer: Leakage in pipes or fittings. Lost water reduces system efficiency and increases operating costs.

Flashcard 14: What is flood irrigation?

Answer: A method that involves flooding fields with water. Simple but inefficient method, often used for rice cultivation.

Flashcard 15: What is surge irrigation?

Answer: A method using intermittent water applications. Pulses water to improve infiltration and reduce runoff.

Flashcard 16: Which method is most efficient in arid regions?

Answer: Drip irrigation. Conserves water in regions with limited rainfall and high evaporation.

Flashcard 17: Which method is best for sandy soils?

Answer: Drip irrigation. Sandy soils drain quickly, so precise application prevents waste.

Flashcard 18: Which method is most suitable for orchards?

Answer: Drip irrigation. Precise water delivery suits tree spacing and root zones.

Flashcard 19: Which method is often used for rice paddies?

Answer: Flood irrigation. Creates standing water conditions ideal for rice growth.

Flashcard 20: Which method is often used for rice paddies?

Answer: Flood irrigation. Creates standing water conditions ideal for rice growth.

Flashcard 21: Which method uses channels between crop rows?

Answer: Furrow irrigation. Water flows in parallel grooves carved between planted rows.

Flashcard 22: What is one risk of over-irrigation?

Answer: Causes nutrient leaching and water waste. Excess water carries nutrients beyond root zones into groundwater.

Flashcard 23: What is one advantage of subsurface irrigation?

Answer: Reduces evaporation and surface runoff. Underground application minimizes water loss to atmosphere.

Flashcard 24: What is one benefit of sprinkler irrigation?

Answer: Even water distribution. Covers large areas uniformly, unlike localized methods.

Flashcard 25: Which method is most suitable for orchards?

Answer: Drip irrigation. Precise water delivery suits tree spacing and root zones.

Flashcard 26: What is sprinkler irrigation?

Answer: A method where water is sprayed over plants like rain. Covers large areas uniformly but uses more water than drip systems.

Flashcard 27: What is localized irrigation?

Answer: Water is applied directly to the plant base. Targets specific plant zones rather than entire field areas.

Flashcard 28: What is the effect of irrigation on groundwater?

Answer: Can recharge or deplete aquifers. Agricultural water use affects underground water table levels.

Flashcard 29: What is the primary goal of irrigation scheduling?

Answer: Optimize water use based on crop demand. Timing applications to match plant growth stages and weather.

Flashcard 30: What is a tailwater recovery system?

Answer: Captures and reuses drainage water. Recycling system that prevents agricultural water waste downstream.

Flashcard 31: What is one risk of over-irrigation?

Answer: Causes nutrient leaching and water waste. Excess water carries nutrients beyond root zones into groundwater.

Flashcard 32: Which method can cause soil salinization if mismanaged?

Answer: Flood irrigation. Excessive water application can concentrate salts in soil.

Flashcard 33: Identify a drawback of center pivot irrigation.

Answer: High initial costs and energy use. Requires significant investment and electricity to operate.

Flashcard 34: What is a main feature of precision irrigation?

Answer: Applies water based on crop needs and weather. Uses sensors and data to optimize water application timing.

Flashcard 35: What is center pivot irrigation?

Answer: A sprinkler system that rotates around a central pivot. Automated system that covers circular areas efficiently.

Flashcard 36: Which method is most efficient in arid regions?

Answer: Drip irrigation. Conserves water in regions with limited rainfall and high evaporation.

Flashcard 37: What is the primary use of furrow irrigation?

Answer: To channel water through small, parallel channels. Water flows in grooves between crop rows for targeted application.

Flashcard 38: Identify one environmental impact of irrigation.

Answer: Can lead to habitat disruption. Water diversions can alter natural ecosystems and wildlife.

Flashcard 39: What is subsurface irrigation?

Answer: Water is applied below the soil surface. Hidden pipes reduce evaporation and surface runoff losses.

Flashcard 40: What is the main component of a pivot system?

Answer: A central tower with rotating arms. Central structure supports rotating sprinkler arms in circular motion.

Flashcard 41: What is surge irrigation?

Answer: A method using intermittent water applications. Pulses water to improve infiltration and reduce runoff.

Flashcard 42: What is subsurface irrigation?

Answer: Water is applied below the soil surface. Hidden pipes reduce evaporation and surface runoff losses.

Flashcard 43: What is the role of an irrigation controller?

Answer: Automates the timing and duration of watering. Electronic device that schedules irrigation based on programmed settings.

Flashcard 44: Identify a drawback of center pivot irrigation.

Answer: High initial costs and energy use. Requires significant investment and electricity to operate.

Flashcard 45: Identify one disadvantage of flood irrigation.

Answer: Can lead to waterlogging and soil erosion. Excess water saturates soil and washes away topsoil.
