Which animal is primarily raised for wool production on a typical farm?
Sheep
Goat
Cow
Pig
Sheep are domesticated ruminants that are primarily raised for their fleece, which is sheared and processed into wool for textiles. Their wool fibers are high in keratin, making them ideal for clothing and insulation. Other animals like goats can produce fibers such as cashmere, but sheep are the most common source of commercial wool.
What is the name of the process by which green plants convert sunlight into chemical energy?
Photosynthesis
Transpiration
Fermentation
Respiration
Photosynthesis is the biochemical process in which plants use chlorophyll to capture sunlight and convert carbon dioxide and water into glucose and oxygen. This reaction is essential for plant growth and forms the basis of most food chains. It differs from respiration, which breaks down sugars to release energy.
Which common farm crop is a staple cereal grain used in bread and pasta?
Soybean
Oats
Wheat
Barley
Wheat is one of the most widely cultivated cereal grains in the world and is the primary ingredient in bread, pasta, and many baked goods. Its gluten content gives dough its elasticity and chewiness. Other grains like barley and oats are important but are not as integral to pasta production.
In farming, what is the primary purpose of a plow?
To shear wool
To break up soil and prepare seedbed
To harvest crops
To irrigate fields
A plow is a farm implement designed to cut, lift, and turn over soil, creating a loose seedbed for planting. It helps incorporate crop residues and manage weeds. Plowing also improves soil aeration and water infiltration.
Which fruit grows on an apple tree?
Peach
Cherry
Apple
Pear
Apple trees (Malus domestica) produce apples, a pome fruit that is one of the most widely cultivated tree fruits. Pears, cherries, and peaches grow on different species of fruit trees. Apples are harvested in late summer to autumn, depending on the variety.
What is the primary material added to make compost?
Synthetic pesticide
Organic plant waste
Chemical fertilizer
Plastic mulch
Compost is made by decomposing organic materials such as plant residues, kitchen scraps, and yard waste under controlled conditions. Microorganisms break down the material into a nutrient-rich soil amendment. Chemical fertilizers and plastics are not compostable.
Which ruminant animal is commonly raised for beef and dairy products?
Duck
Cow
Pig
Chicken
Cows are ruminant mammals with a four-compartment stomach specialized for digesting fibrous plant material and are raised worldwide for beef and milk production. Chickens, pigs, and ducks are monogastric and are raised for meat and eggs but not dairy.
What do bees primarily collect from flowers?
Sap
Nectar
Pollen
Resin
Bees collect nectar, a sugar-rich liquid produced by flowers, which they convert into honey. They also gather pollen as a protein source, but nectar is their primary energy resource. Sap and resin are collected by other insects but not typically by bees.
What method is used to preserve forage crops through fermentation under anaerobic conditions?
Haymaking
Mulching
Silage
Composting
Silage is forage (such as corn or grass) harvested and stored in silos or pits where anaerobic fermentation preserves it. Lactic acid bacteria ferment the sugars, lowering pH and preventing spoilage. Haymaking instead dries the forage, and composting breaks down waste for soil amendment.
In the "Three Sisters" companion planting method, which of the following sets of crops are planted together?
Corn, beans, and squash
Wheat, barley, and oats
Potato, tomato, and onion
Tomato, lettuce, and carrot
The Three Sisters is a traditional Native American technique where corn, beans, and squash are interplanted. Corn provides a trellis for beans, beans fix nitrogen, and squash covers the soil to suppress weeds. This synergy boosts yield and soil health.
Ideal soil pH for most crops ranges between:
4.5 to 5.5
3.0 to 4.0
6.0 to 7.5
8.0 to 9.5
Most agricultural crops thrive in slightly acidic to neutral soils, with pH between 6.0 and 7.5. This range optimizes nutrient availability and microbial activity. Soils below pH 5.5 can lead to aluminum toxicity, while above pH 8 can cause micronutrient deficiencies.
Which irrigation technique delivers water directly to the plant roots using flexible tubing and emitters?
Drip irrigation
Flood irrigation
Furrow irrigation
Sprinkler irrigation
Drip irrigation uses a network of tubes and emitters to supply water drop by drop at the plant's root zone. This system conserves water and reduces evaporation and runoff. Flood and furrow methods deliver water less precisely.
Which genetically modified crop is engineered for pest resistance using Bt toxin?
Golden Rice
Roundup Ready alfalfa
Herbicide-tolerant soybean
Bt corn
Bt corn is genetically engineered to express Bacillus thuringiensis (Bt) toxins that target specific insect pests, reducing the need for chemical insecticides. Herbicide-tolerant crops resist specific herbicides but do not produce Bt toxins. Golden Rice is modified for provitamin A content.
What certification must farms obtain to label their products as organic in the United States?
Rainforest Alliance
Non-GMO Project Verified
Fair Trade
USDA Organic
The USDA Organic seal indicates that a farm complies with federal standards for organic production, including soil management, pest control, and no synthetic fertilizers or GMOs. Fair Trade and Rainforest Alliance are social responsibility certifications, while Non-GMO verifies absence of genetic modification only.
What grazing system involves rotating livestock between pastures to allow forage regrowth?
Rotational grazing
Continuous grazing
Silvopasture
Strip cropping
Rotational grazing moves livestock through a series of paddocks, allowing grazed areas to recover and regrow. This improves forage quality, soil health, and pasture longevity. Continuous grazing keeps animals in one area, often leading to overgrazing.
Which of the following crops uses the C4 photosynthetic pathway and is more water-efficient in hot climates?
Wheat
Soybean
Rice
Maize
Maize (corn) employs the C4 pathway, which minimizes photorespiration and conserves water under high light and temperature conditions. Rice, soybean, and wheat are C3 plants and are generally less efficient under hot, arid conditions. C4 photosynthesis allows stomata to open less, reducing water loss.
Leguminous plants like clover improve soil nitrogen through a symbiotic relationship with which type of bacteria?
Rhizobia
Nitrosomonas
Clostridium
Azotobacter
Rhizobia bacteria form nodules on the roots of legumes and convert atmospheric nitrogen into ammonia through nitrogen fixation. This process enriches soil fertility without synthetic fertilizers. Azotobacter is free-living, while Nitrosomonas and Clostridium have different roles in the nitrogen cycle.
Methane emissions from livestock largely result from which biological process in ruminants?
Denitrification
Nitrification
Enteric fermentation
Manure composting
Enteric fermentation is the digestive process in ruminants where microbes break down feed in the rumen, producing methane as a byproduct. This methane is expelled by belching. Manure can also emit methane but enteric fermentation is the primary source in livestock.
Monoculture farming is primarily characterized by:
Growing multiple crops in the same field
Integrating livestock and crops
Using biological pest control
Cultivation of a single crop species over a large area
Monoculture refers to growing one crop species on a large scale, which can simplify management but may increase vulnerability to pests and diseases. Polyculture involves multiple crops, and integrated approaches combine crops with livestock or use biological controls.
One benefit of no-till farming is:
Elimination of cover crops
Reduced soil erosion
Higher soil compaction
Increased diesel use
No-till farming leaves crop residues on the field and avoids plowing, which significantly reduces soil erosion and water runoff. It can also increase soil organic matter over time. Diesel use and compaction effects vary, but soil protection is a core benefit.
Integrated Pest Management (IPM) emphasizes:
Exclusive use of pesticides
Combining biological, cultural, and chemical controls in a sustainable way
Organic certification only
Single-crop focus
IPM is a holistic approach that integrates biological controls (like beneficial insects), cultural practices (crop rotation), and judicious pesticide use to manage pests with minimal environmental impact. It is not limited to organic or chemical methods alone.
Which dairy cattle breed is known for high butterfat content in milk?
Jersey
Angus
Hereford
Holstein
Jersey cows produce milk with higher butterfat and protein content compared to other common dairy breeds. Holsteins yield larger volumes of milk but with lower fat content. Angus and Hereford are beef breeds.
In precision agriculture, NDVI sensors are used primarily to assess:
Irrigation pump efficiency
Plant health and biomass density
Soil pH levels
Livestock weight
Normalized Difference Vegetation Index (NDVI) sensors measure light reflectance to estimate plant vigor, chlorophyll content, and biomass. This data helps farmers apply inputs variably across fields. NDVI does not directly measure soil pH or equipment performance.
Which hydroponic technique involves a thin film of nutrient-rich water flowing over plant roots?
Ebb and Flow
Aeroponics
Deep Water Culture
Nutrient Film Technique (NFT)
The Nutrient Film Technique (NFT) uses a continuous, shallow stream of water containing dissolved nutrients that flows over the roots of plants in a slightly tilted channel. Roots absorb nutrients directly, and excess solution recirculates. Deep Water Culture submerges roots entirely, and Aeroponics mists roots in air.

Cheat Sheet

  1. Photosynthesis Pathways in Crops -

    Understand the C3, C4, and CAM photosynthetic pathways - C3 plants (e.g., wheat) fix CO₂ via the Calvin cycle, C4 plants (e.g., maize) use a CO₂-concentrating mechanism, and CAM plants (e.g., pineapple) open stomata at night. The general photosynthesis equation (6CO₂ + 6H₂O → C₆H₝₂O₆ + 6O₂) appears in USDA crop reports; use the mnemonic "Six Six to Sugar and Air" to recall it.

  2. Ruminant Digestion in Livestock -

    Ruminants like cattle and sheep have a four-chambered stomach: rumen, reticulum, omasum, and abomasum (University of California Davis Extension). Remember "Really Really Odd Animals" to recall the order. Efficient fiber breakdown by rumen microbes supplies up to 70% of energy needs for milk and meat production.

  3. Soil Texture and pH Management -

    Use the soil texture triangle (NRCS, USDA) to classify soils by sand, silt, and clay percentages for water retention and aeration. Aim for a neutral pH of 6.0 - 7.5 in most crops; test kits or lab analyses from extension services can guide lime or sulfur applications to adjust acidity.

  4. Crop Rotation and Nitrogen Fixation -

    Rotating cereals with legumes (e.g., soybeans) breaks pest cycles and enriches soil nitrogen - legumes supply up to 100 kg N/ha via symbiotic Rhizobium bacteria (FAO). A simple "Cereal - Legume - Cereal" three-year rotation is widely recommended by land”grant universities for sustainable yields.

  5. Irrigation Methods and Efficiency -

    Compare drip (up to 90% water-use efficiency) versus sprinkler systems (around 75%), according to FAO irrigation guidelines. Use the memory aid "Drip Dazzles" - precision delivery reduces evaporation and runoff, boosting crop water-use efficiency and lowering energy costs.
