Worked Solution & Example Answer:2.1 Describe how strong winds can influence crop production negatively - NSC Agricultural Management Practices - Question 2 - 2020 - Paper 1
Step 1
Describe how strong winds can influence crop production negatively.
Answer
Strong winds can have several negative impacts on crop production:
-
Damage to Plant Structures: High winds can cause physical damage to leaves, flowers, and fruits, resulting in reduced photosynthesis and lower yields.
-
Increased Evaporation: Strong winds can accelerate transpiration, leading to higher water loss from crops. This can stress plants and hinder growth.
-
Soil Erosion: Winds can uproot plants and erode the topsoil, leading to nutrient loss and a decrease in soil fertility, ultimately affecting overall production.
Step 2
Step 3
Name FOUR protective measures that workers must consider when working with dangerous substances.
Answer
- Proper Protective Clothing: Workers should use protective gear such as gloves and masks when handling chemicals.
- Washing Hands after Contact: It's essential to wash hands thoroughly after using chemicals to prevent contamination.
- Correct Handling Procedures: Follow chemical manufacturer instructions for safe handling and application.
- Training: Workers should receive proper training on how to handle chemicals safely.
Step 4

Step 8
Discuss FIVE ways of protecting soil fertility against erosion and loss of nutrients.
Answer
-
Cover Cropping: Planting cover crops can reduce soil erosion while improving soil health.
-
Crop Rotation: Rotating crops helps maintain soil fertility by preventing nutrient depletion.
-
Conservation Tillage: Reducing tillage minimizes soil disturbance, preserving soil structure and nutrients.
-
Use of Organic Matter: Adding organic materials like compost improves soil structure and fertility.
-
Water Management: Implementing proper irrigation techniques minimizes water runoff and erosion.
Step 9
Distinguish between commercial farming and subsistence farming with regard to the following aspects: Use of technology.
Answer
Commercial farming often employs advanced technology for efficiency and productivity, while subsistence farming typically relies on traditional methods and minimal technology.
Step 10
Distinguish between commercial farming and subsistence farming with regard to the following aspects: Volume of output.
Answer
Commercial farming focuses on producing large quantities of crops for sale, while subsistence farming aims to produce just enough for the farmer's family and local community.
Step 11
Give an explanation of why some camps are bigger than others.
Answer
Some camps are larger due to the need for more grazing area to support a larger herd or to accommodate the nutritional requirements of livestock. Additionally, larger camps might be necessary if the grazing land has varying vegetation types.
Step 12
Discuss the advantages of the wagon wheel layout (A).
Answer
- Centralized Water Access: The water trough is centrally located, ensuring easy access for all animals.
- Reduced Labour Costs: Less movement is required to manage livestock, leading to lower labour costs.
- Easier Maintenance: The layout minimizes infrastructure maintenance, as everything is centralized.
Step 13
Step 14
Give THREE reasons why it is necessary to give camps a resting period in a rotational grazing system.
Answer
- Improved Regrowth: Resting allows grass to regrow, enhancing overall pasture quality.
- Soil Recovery: A resting period helps in soil rejuvenation and water retention.
- Pest Management: Resting reduces the risk of pest and disease build-up in overgrazed areas.
Step 15
Discuss the influence of the following TWO properties on the production capability of the soil: Soil colour.
Answer
Soil colour can indicate its nutrient content and drainage capabilities. For example, red or yellow soils are often well-drained and fertile, while dark soils may indicate high organic matter content beneficial for crop production.
Step 16
Discuss the influence of the following TWO properties on the production capability of the soil: Soil texture.
Answer
Soil texture affects water retention and nutrient availability. Sandy soils drain quickly and can be less fertile, while clay soils retain water and nutrients better, making them usually more fertile.
Step 17
Discuss the effect of soil pollution that occurs due to the incorrect application of pesticides, under the following headings: Soil degradation.
Answer
Soil degradation through pesticide overuse can harm beneficial organisms, leading to reduced soil fertility. This can contribute to barren areas and a loss of vegetation, harming ecosystems.
Step 18
Discuss the effect of soil pollution that occurs due to the incorrect application of pesticides, under the following headings: Water pollution.
Answer
Improper pesticide application can lead to runoff, contaminating nearby water bodies. This can affect fish and other organisms, thereby disrupting entire ecosystems.
