2.1 Describe how strong winds can influence crop production negatively - NSC Agricultural Management Practices - Question 2 - 2020 - Paper 1

The Occupational Health and Safety Act of 1993 (Act 85 of 1993) provides for a safe workplace.

1. Wash hands after using chemicals to prevent contamination.
2. Use protective clothing such as gloves and goggles.
3. Ensure chemicals are stored safely and away from food sources.
4. Be trained to work with chemicals to understand risks and handling procedures.

1. Implementing additional measures for organic material reduction to prevent erosion.
2. Ensuring good ground cover is maintained to protect soil structure.
3. Utilizing minimum tillage practices to minimize soil disturbance.
4. Adopting correct cultivation practices to promote better water retention.
5. Implementing mulching to reduce surface water runoff.

Commercial farming typically employs mechanized methods and advanced technology to maximize productivity, while subsistence farming relies on traditional practices and animal traction.

Commercial farming yields larger outputs intended for sale, while subsistence farming generates smaller quantities primarily for family consumption.

Some camps are larger because they must accommodate livestock with similar dietary needs and palatability of available grazing resources. A larger area also allows for better nutrition consistency when natural resources are more abundant.

1. The water trough's central position optimizes access for livestock.
2. Maintenance is simpler due to fewer fencing requirements.
3. It minimizes labor costs by reducing unnecessary movements for tending livestock.

To manage differing camp sizes effectively, the farmer can adjust the time that animals spend in smaller camps to shorter durations, ensuring adequate grazing for each group.

1. To allow the maximum production of grazing material to occur.
2. To give mature plants a chance to recover and sequester nutrients.
3. To encourage overgrazed areas to regain fertility.

Soil colour often indicates drainage capability; red/yellow soils typically have good drainage, promoting crop growth when sufficient moisture is present. Dark/brown soils usually have organic matter and fertility, which is beneficial for farming.

Soil texture affects water retention and infiltration rates. Sandy soils drain well but can struggle to retain longevity without adequate rainfall, while clay soils can hold water effectively, often yielding better fertility due to retained nutrients.

A high concentration of pesticides can lead to severe soil organism depletion, impacting plant health and biodiversity. It can also lead to areas with bare soil, inhibiting new crop growth.

Pesticides can leach into nearby water sources from the contaminated soil, leading to broader ecological consequences such as harmful effects on aquatic organisms and the disruption of water quality.

1. Plowing fields to prepare the soil for planting.
2. Pulling carts for transporting harvested produce.
