Answer Details

(a) Five reasons why the government should enact laws to regulate the use of land for agriculture are:

1. Environmental protection: Agriculture practices can have significant impacts on the environment, including soil erosion, pollution of waterways, and loss of biodiversity. Laws can ensure that farming practices are conducted in a sustainable manner that minimizes harm to the environment.

2. Food safety: Laws can ensure that the food produced by farmers is safe for human consumption by regulating the use of pesticides, herbicides, and other chemicals.

3. Land use planning: Laws can help to ensure that land is used efficiently and that there is enough land available for agriculture.

4. Animal welfare: Laws can regulate the treatment of animals on farms to ensure that they are treated humanely.

5. Economic benefits: Laws can create a level playing field for farmers by regulating the use of subsidies, price controls, and other measures that can distort markets.

(b) (i) The most appropriate type of farm power to use for tillage operations on a 10-hectare cocoa farm is a tractor.

(ii) Four reasons for using a tractor for tillage operations on a cocoa farm are:

1. Efficiency: Tractors are faster and more efficient than manual labor or animal-drawn implements, allowing the farmer to cover more ground in less time.

2. Power: Tractors have greater power and traction than animal-drawn implements, allowing them to work in tougher conditions and handle heavier loads.

3. Versatility: Tractors can be used for a range of farming operations beyond tillage, including planting, spraying, and harvesting.

4. Cost-effectiveness: Tractors can be expensive to purchase or hire, but their increased efficiency and productivity can lead to long-term cost savings for the farmer.

(c) One function of each of the following parts of a seed planter are:

(i) Seed tube: The seed tube delivers the seed to the furrow created by the furrow opener.

(ii) Furrow opener: The furrow opener creates a shallow trench in the soil for the seed to be planted in.

(iii) Hopper: The hopper holds the seed until it is dropped into the furrow by the seed metering device.

(iv) Seed metering device: The seed metering device measures out the correct amount of seed to be dropped into the furrow.

(v) Furrow wheel: The furrow wheel closes the furrow over the seed after it has been planted.

(d) Three machines used in processing crops after harvesting are:

1. Combine harvester: A machine that cuts, threshes, and cleans grain crops such as wheat, barley, and corn.

2. Thresher: A machine that separates grain from the straw and chaff of cereal crops such as rice, wheat, and oats.

3. Winnowing machine: A machine that separates the grain from the chaff by blowing air over the mixture, allowing the lighter chaff to be blown away while the heavier grain falls to the ground.
