2.1 Water is the single most important substance for any living being - NSC Agricultural Management Practices - Question 2 - 2021 - Paper 1

1. Rainfall intensity and how frequently it rains.
2. Tempo of evaporation during the day.
3. Seasonal distribution of rainfall.
4. Soil condition, including texture and ability to retain moisture.

Trampling by animals leads to damage of the feed available, which can decrease the total grazing area. This, in turn, reduces the carrying capacity of the camp as fewer animals can be sustained, causing even more strain on the available resources.

1. Provide extra feed supplements to the lactating cows to meet their nutritional needs.
2. Store additional feed during periods of surplus to ensure availability during the calving season.

The agricultural term for the relationship illustrated in the graph is the law of diminishing returns.

Marginal yield refers to the additional output generated from the last unit of input used, demonstrating the profit that can be achieved beyond the normal yield.

Point A represents the stage where any additional fertiliser applied does not lead to any extra profitable income. Beyond this point, the farmer would incur costs without benefitting from increased yields, indicating a need for careful resource management.

1. Production capital, which is capital obtained from selling goods or livestock. This includes savings accumulated from previous earnings.
2. External sources such as loans from banks or investors, providing necessary funds for operations.

1. Capital can be scarce, leading to limited resources for necessary investments.
2. High interest rates can make borrowing challenging and expensive.
3. Insufficient collateral may prevent farmers from obtaining loans.

Conventional planter is cheaper/lower cost compared to a no-till planter, which is more expensive/higher cost.

Conventional planter has high cultivation costs, while no-till planter has lower cultivation costs.

Conventional planter requires less traction, while no-till planter needs a greater number of larger tractors.

1. Wind speed can greatly affect the direction and distance that spray drifts.
2. Humidity levels can influence the droplet size and evaporation rates.
3. The applicator's height from the crop can determine how much drift occurs.

1. Low returns on high development costs can make agritourism unviable.
2. Poor infrastructure may hinder access and convenience for potential tourists.
3. Lack of essential skills among farmers can result in inadequate service delivery.

1. A small market segment that targets specific clients or customers.
2. A higher price range due to the uniqueness of the offered products.
3. Specialized products that meet distinct demands.

1. The condition of the implement in relation to a new one.
2. The price of the implement compared to new options.
3. The cost to repair or maintain the implement for efficient functioning.
