5.15 - Sustainable Agriculture Quiz

What is the purpose of crop rotation in sustainable agriculture?

• To limit the variety of crops and increase the reliance on chemical pesticides

• To decrease soil fertility and promote the spread of pests and diseases

• To improve soil fertility, control pests and diseases, and reduce the need for chemical fertilizers and pesticides.

• To reduce water usage and increase the need for chemical fertilizers

How does crop rotation help in reducing the need for chemical fertilizers and pesticides?

• By attracting more pests and diseases to the crops

• By depleting the soil nutrients and making it more reliant on chemicals

• By causing soil erosion and reducing its fertility

• By naturally replenishing the soil nutrients and disrupting pest and disease cycles.

What are the benefits of agroforestry in sustainable agriculture?

• Improving soil fertility, conserving water, providing habitat for wildlife, and diversifying income sources for farmers

• Causing deforestation

• Reducing crop yield

• Increasing air pollution

How does agroforestry contribute to biodiversity conservation?

• Agroforestry provides diverse habitats for various species of plants and animals.

• Agroforestry only benefits a single species of plant or animal.

• Agroforestry has no impact on biodiversity conservation.

• Agroforestry destroys habitats for plants and animals.

What is integrated pest management (IPM) and how does it promote sustainable agriculture?

• IPM promotes sustainable agriculture by reducing reliance on chemical pesticides, minimizing environmental impact, and preserving natural resources.

• IPM promotes sustainable agriculture by depleting natural resources and causing environmental damage

• IPM promotes sustainable agriculture by increasing the use of chemical pesticides and harming the environment

• IPM promotes sustainable agriculture by encouraging the use of genetically modified organisms and increasing pollution

How does IPM differ from traditional pest control methods?

• IPM uses only chemical pesticides

• IPM does not consider long-term prevention

• IPM focuses on eradicating pests completely

• IPM focuses on long-term prevention of pests through a combination of techniques.

What are some common soil conservation practices in sustainable agriculture?

• Using synthetic fertilizers

• Overgrazing by livestock

• Clear-cutting forests

• Crop rotation, cover cropping, no-till farming, contour plowing, and terracing

How does soil conservation help in preventing soil erosion and maintaining soil fertility?

• By implementing practices like contour plowing, terracing, planting cover crops, crop rotation, organic farming, and minimizing tillage.

• By using chemical fertilizers and pesticides

• By overgrazing the land and removing all vegetation

• By cutting down all the trees and vegetation

What are the key principles of water management in sustainable agriculture?

• No water conservation practices, inefficient irrigation techniques, and improper drainage systems

• Excessive use of water, poor irrigation techniques, and inadequate drainage systems

• Efficient irrigation techniques, water conservation practices, and proper drainage systems

• Limited use of water, lack of irrigation techniques, and no need for drainage systems

How does efficient water management contribute to sustainable agriculture?

• By using more water than necessary for irrigation

• By using outdated and inefficient irrigation methods

• By allowing water to run off without being absorbed by the soil

• By conserving water resources, reducing water wastage, and ensuring proper irrigation for crops.
