Past Questions for WAEC Agric Science Exam
Practicing past questions is one of the most effective ways to prepare for the WAEC Agric Science exam. Below are sample past questions based on the most repeated topics:
Sample Past Question 1:
Question:
Explain the importance of crop rotation in maintaining soil fertility.
Answer:
- Crop rotation helps to reduce the build-up of pests and diseases that affect specific crops.
- It helps to replenish soil nutrients by alternating crops that use different nutrients.
- It reduces soil erosion by maintaining good soil structure and organic matter.
Sample Past Question 2:
Question:
Describe the process of soil erosion and suggest two methods of preventing it.
Answer:
- Soil erosion is the process by which the topsoil is washed away by wind or water, reducing the soil’s ability to retain nutrients and support crop growth.
- Two methods of preventing soil erosion:
- Terracing: Creating steps on hilly terrain to slow down the movement of water.
- Planting cover crops: Such as grasses or legumes, to protect the soil surface from direct rainfall impact.
Sample Past Question 3:
Question:
Identify four breeds of livestock commonly raised in Nigeria for meat production.
Answer:
- Cattle: Such as the White Fulani breed.
- Goats: The West African Dwarf breed.
- Sheep: The Red Sokoto breed.
- Poultry: The Broiler breed of chicken.
Sample Past Question 4:
Question:
What is integrated pest management (IPM), and why is it important in crop production?
Answer:
- Integrated Pest Management (IPM) is an environmentally friendly approach to controlling pests using a combination of methods such as biological control, chemical control, and cultural practices.
- It is important because it helps to control pests effectively while minimizing the impact of pesticides on the environment, human health, and beneficial organisms.
