Memos

Paper 1

Section A: Multiple Choice

1. (c)
2. (b)
3. (d)
4. (a)
5. (d)

Section B: Short Answer

Answers may vary, but should include the following key points:

• Advantages of monoculture: High yields, efficient use of resources, reduced labor costs.
• Disadvantages of monoculture: Increased risk of pests and diseases, soil depletion, loss of biodiversity.
• Benefits of crop rotation: Reduced pest and disease pressure, improved soil fertility, increased water retention.
• Importance of soil conservation practices: Prevent soil erosion, maintain soil fertility, improve water infiltration.
• Methods of irrigation: Drip irrigation (water-efficient, reduces evaporation), sprinkler irrigation (uniform water distribution), flood irrigation (simple and inexpensive).
• Role of organic matter in soil fertility: Provides nutrients, improves soil structure, increases water retention.

1. (d)
2. (a)
3. (d)
4. (c)
5. (d)

Section B: Short Answer

Answers may vary, but should include the following key points:

• Factors affecting choice of crop: Climate, soil type, market demand, availability of labor.
• Advantages of mixed farming: Reduced risk, improved soil fertility, increased biodiversity.
• Disadvantages of mixed farming: Requires more management, lower yields than specialized farming.
• Importance of animal husbandry practices: Improve animal health and productivity, reduce disease risk, ensure animal welfare.
• Types of livestock management systems: Extensive grazing (low input, large land area), intensive confinement (high input, controlled environment), semi-intensive grazing (combination of grazing and confinement).
• Role of technology in modern agricultural practices: Precision farming, automated irrigation, genetic engineering, improved animal breeding.
