Worked Solution & Example Answer:Water is the single most important substance for any living being - NSC Agricultural Management Practices - Question 2 - 2021 - Paper 1
Step 1
Step 2
2.1.2 Name FOUR factors that determine the effectiveness of rainfall.
Answer
The effectiveness of rainfall for a farmer can be determined by the following factors:
- Rainfall Intensity: The amount of rainfall and how intense it is can greatly impact its effectiveness.
- Tempo of Evaporation: The rate at which water evaporates can affect how much is retained for crops and soil.
- Soil Condition: The condition of the soil, including its structure and texture, influences water retention.
- Topography: The slope and landscape can affect water distribution and absorption.
Step 3
2.2.1 Explain the effect of trampling of the feed available and the carrying capacity of a camp.
Answer
Trampling can lead to damaged feed resources in a camp, which ultimately reduces the amount of food available for grazing animals. This decreases the carrying capacity since fewer animals can be supported due to the compromised feed quality, affecting overall farm productivity.
Step 4
2.2.2 Name TWO methods that a farmer can use to overcome the required feed for lactating cows during the calving season.
Answer
To overcome the required feed for lactating cows during the calving season, a farmer may:
- Reduce the Number of Breeding Animals: This allows for better management of available feed resources.
- Store Feed: Keeping additional feed in reserve ensures that animals have enough nutrition during critical times such as calving.
Step 5
Step 6
2.3.2 Describe the term marginal yield.
Answer
Marginal yield refers to the additional yield obtained from using one more unit of an input, such as fertiliser. It indicates how much more produce is generated by increasing inputs, and helps farmers assess the efficiency of their operations.
Step 7
2.3.3 Explain the implications of point A on the graph.
Answer
Point A on the graph signifies a stage where increasing the fertiliser input does not result in significant additional income. Beyond this point, the costs of input might outweigh the benefits, indicating that the farmer risks financial loss if additional fertiliser is applied without achieving proportional yield gains.

Step 11
Step 12
2.5.1 Name and explain TWO main sources of capital for a farming business.
Answer
Two main sources of capital for a farming business include:
- Production Capital: This is capital obtained from selling goods produced by the farm which can be reinvested.
- Savings: This consists of accumulated funds from previous seasons, which can be used for operational costs or investments.
Step 13
2.5.2 Give THREE problems related to capital as a production factor.
Answer
Three problems related to capital as a production factor include:
- Scarcity of Capital: Limited funds can hinder growth and operational efficiency.
- High Interest Rates: Costly borrowing can make it difficult to finance necessary investments.
- Over-Capitalisation: Investing too heavily may lead to financial strain and insufficient return on investment.
Step 14
2.6 Compare a conventional planter with a no-till planter based on the following aspects: - Cost of the planter - Cultivation costs - Traction required.
Answer
| Aspect | Conventional Planter | No-Till Planter |
|---|---|---|
| Cost of the planter | Cheaper/Lower cost | Expensive/Higher cost |
| Cultivation costs | High cultivation costs | Lower cultivation costs |
| Traction required | Less traction/smaller tractor | Greater pull/bigger tractor needed |
Step 15
2.7 Name THREE factors that will influence the drift of spray during the application of a pesticide.
Answer
Three factors that influence drift include:
- Droplet Size: Smaller droplets are more prone to drift.
- Wind Speed: Higher winds can carry droplets away from the target area.
- Temperature: Fluctuations may affect the evaporation rate of the spray.
Step 16
2.8 Describe THREE challenges of agritourism in rural areas.
Answer
Three challenges of agritourism include:
- Low Returns on High Development Cost: Initial investment might not lead to expected profits.
- Lack of Essential Skills: Farmers may need training in hospitality and marketing.
- Poor Infrastructure: Inadequate roads and facilities can deter visitors.
Step 17
2.9 Name THREE characteristics of a niche market.
Answer
Three characteristics of a niche market include:
- Small Market Segment: Focuses on specific client demographics.
- Targeted Products/Services: Offers specialized goods that meet unique needs.
- Higher Price Range: Often allows for premium pricing due to specialized offerings.
Step 18
2.10 Name THREE aspects that a farmer must consider when acquiring used (second-hand) implements.
Answer
Three aspects to consider include:
- Condition of the Implement: Ensures that it is still functional and has longevity.
- Cost in Relation to a New One: Evaluate if the savings justify the used option.
- Compatibility with Existing Equipment: Ensures it integrates smoothly into current operations.
