Explanation The correct answer is "Very large farm holdings." This means that extensive pastoralism involves having farms with a significant amount of land. This is different from small blocks of land, as mentioned in one of the options. The other options, such as excellent road access, high output per hectare, and a lot of cheese products, may be associated with extensive pastoralism but are not the defining characteristic.

Dairy farming is located in areas which are
A.
Hilly/rocky
B.
Lowland/plain
C.
Central to urban development
D.
Stoney
E.
Sandy
Correct Answer
B. Lowland/plain
Explanation Dairy farming is located in lowland/plain areas because these regions provide flat terrain, which is ideal for grazing and cultivating crops for livestock feed. Lowland areas also tend to have fertile soil, access to water sources, and favorable climatic conditions for the growth of forage crops. Additionally, lowland areas are usually closer to markets and infrastructure, making it easier to transport milk and dairy products.

For a dairy farm to run efficiently it requires
A.
Cold temperatures
B.
Close proximity to the sea
C.
Quad-bikes
D.
Fertile soils
E.
Poor acessibility
Correct Answer
D. Fertile soils
Explanation Fertile soils are essential for a dairy farm to run efficiently because they provide the necessary nutrients for the growth of nutritious and abundant pasture. This pasture is then consumed by the cows, resulting in high-quality milk production. Fertile soils also support the growth of other crops and forage that can supplement the cows' diet. Without fertile soils, the farm would struggle to produce enough feed for the cows, leading to lower milk production and potentially higher costs for purchasing feed from external sources.

An example of a natural input is
A.
Water pollution
B.
Effluent
C.
Alluvial, free-draining soils
D.
Calves
E.
The Farmer
Correct Answer
C. Alluvial, free-draining soils
Explanation Alluvial, free-draining soils can be considered as a natural input because they occur naturally in the environment and are not created or influenced by human activities. These soils are formed by the deposition of sediments carried by rivers and are characterized by their ability to drain water easily. As a result, they provide a favorable environment for plant growth and are often used in agriculture due to their high fertility and good water drainage properties.

In a Dairy farming system feedbacks are
A.
Ouputs which are lost from the system
B.
Outputs which are used by the system as inputs
C.
Reports written at each seasonal transition
D.
The actions done by farmers to turn inputs into outputs
Correct Answer
B. Outputs which are used by the system as inputs
Explanation In a dairy farming system, feedbacks refer to the outputs that are used by the system as inputs. This means that the outputs of the system, such as milk or manure, are utilized as inputs for various processes within the farming system. This feedback loop helps in maintaining the functioning and productivity of the dairy farming system.

Friesian's are good for
A.
Their wet noses
B.
Lower fat content, but higher output
C.
Higher fat content, but lower output
D.
Cheese and butter making
Correct Answer
B. Lower fat content, but higher output
Explanation Friesian cows are known for having lower fat content in their milk but higher milk output compared to other breeds. This means that while the milk from Friesian cows may have less fat, they are able to produce larger quantities of milk. This characteristic makes Friesian cows suitable for cheese and butter making, as these products typically require a higher milk yield. The wet noses mentioned in the question are not relevant to the answer.

Correct Answer rotary
Explanation This is a type of milking shed called a rotary.
Rate this question:
11.
In break-feeding
A.
A change of paddock after each milking allows grass to recover before it is grazed again
B.
Movable electric fences allow strict control of grazing
C.
Hay is distributed to cows directly after milking
D.
Calves are weaned off their mothers milk in portions
Correct Answer
B. Movable electric fences allow strict control of grazing
Explanation Movable electric fences allow strict control of grazing by creating temporary boundaries that can be easily adjusted and moved. This allows for rotational grazing, where animals are moved to different paddocks after each milking. By doing so, the grass in each paddock has time to recover before it is grazed again, ensuring a sustainable and healthy food source for the cows. This method also allows farmers to control the amount of grass consumed by the cows, preventing overgrazing and promoting optimal pasture management.

An example of a Dairy farming feedback is _________
Correct Answer manure profits replacement stock hay silage
Explanation Dairy farming feedback refers to the information or results obtained from the various aspects of dairy farming. This includes the use of manure as a natural fertilizer for crops, which helps improve soil fertility and crop yields. Profits are another form of feedback, indicating the financial success of the dairy farm. Replacement stock refers to the process of replacing older or unproductive cows with younger and more productive ones, ensuring the overall health and productivity of the herd. Hay and silage are important feed sources for dairy cows, providing necessary nutrients and sustenance.

Air pollution is an environmental problem caused by Dairy farming
A.
True
B.
False
Correct Answer
A. True
Explanation Air pollution can be caused by various sources, including dairy farming. Dairy farming contributes to air pollution through the release of methane gas from cow manure, which is a potent greenhouse gas. Additionally, the use of machinery and vehicles in dairy farming operations can also release pollutants into the air. Therefore, it is true that dairy farming can be a cause of air pollution.

Algal bloom is caused when
A.
Native flora attempt to attract pollinators
B.
Farmers stop fertilising their land
C.
Excess fertiliser is washed into water-ways
D.
Cows get parasitic infections
Correct Answer
C. Excess fertiliser is washed into water-ways
Explanation Excess fertiliser being washed into waterways is the cause of algal bloom. When fertilisers are used in excessive amounts, they can be carried away by rain or irrigation water, ultimately ending up in rivers, lakes, or other water bodies. These excess nutrients, such as nitrogen and phosphorus, act as a food source for algae, causing their rapid growth and multiplication. As a result, algal blooms occur, leading to the depletion of oxygen in the water, harm to aquatic life, and disruption of the ecosystem.

A solution to waterway pollution would be
A.
Use of races
B.
Use of a feeding pad
C.
Carp ponds
D.
Riparian management
Correct Answer
D. Riparian management
Explanation Riparian management refers to the practice of managing and protecting the vegetation and land along the banks of waterways. This can help to prevent waterway pollution by reducing the amount of sediment, nutrients, and pollutants that enter the water. By maintaining a healthy riparian zone, the vegetation can act as a buffer, filtering runoff and trapping pollutants before they reach the water. This can improve water quality, protect aquatic habitats, and promote overall ecosystem health. Therefore, riparian management is a viable solution to waterway pollution.
