APES Sustainable Agriculture Practices
36 flashcards covering APES Sustainable Agriculture Practices for the AP-ENVIRONMENTAL-SCIENCE Unit 5 section.
Sustainable agriculture practices encompass methods that aim to meet current food needs while preserving the environment for future generations. This topic is defined by the College Board's AP Environmental Science curriculum, which emphasizes the importance of environmentally sound agricultural techniques, soil management, and biodiversity conservation. Understanding these practices is crucial for addressing challenges such as soil degradation, water scarcity, and climate change.
On practice exams and competency assessments, questions about sustainable agriculture often focus on specific techniques, such as crop rotation, agroforestry, and organic farming. These questions may require you to analyze case studies or evaluate the effectiveness of various methods. A common pitfall is misinterpreting the benefits of monoculture versus polyculture; many candidates overlook the long-term ecological advantages of diverse cropping systems.
One practical tip is to consider local ecosystems when implementing sustainable practices, as what works in one region may not be suitable in another.

Which practice helps reduce water usage in sustainable agriculture?
Drip irrigation is a practice that helps reduce water usage by delivering water directly to the plant roots, minimizing evaporation and runoff (College Board AP CED).
- 10
What is the benefit of using native plants in sustainable landscaping?
Using native plants in sustainable landscaping enhances local biodiversity, requires less maintenance, and reduces the need for chemical fertilizers and pesticides (College Board AP CED).
- 11
How often should farmers rotate their crops to maintain soil health?
Farmers should rotate their crops annually or every growing season to maintain soil health and prevent pest and disease buildup (College Board AP CED).
- 12
What is one benefit of using integrated pest management (IPM)?
One benefit of using integrated pest management (IPM) is that it reduces reliance on chemical pesticides, promoting environmental sustainability and reducing health risks (College Board AP CED).
- 13
What is the impact of monoculture on soil health?
Monoculture can lead to soil degradation, reduced biodiversity, and increased vulnerability to pests and diseases due to the lack of crop diversity (College Board AP CED).
- 14
Which agricultural practice enhances carbon sequestration?
Agroforestry enhances carbon sequestration by integrating trees and shrubs into agricultural landscapes, capturing carbon dioxide from the atmosphere (College Board AP CED).
- 15
What is the significance of permaculture in sustainable agriculture?
Permaculture emphasizes designing agricultural systems that mimic natural ecosystems, promoting sustainability, resilience, and resource efficiency (College Board AP CED).
- 16
How can cover crops benefit soil during the off-season?
Cover crops can benefit soil during the off-season by preventing erosion, suppressing weeds, and adding organic matter when they decompose (College Board AP CED).
- 17
What is the role of crop diversity in sustainable agriculture?
Crop diversity plays a crucial role in sustainable agriculture by enhancing ecosystem resilience, improving pest management, and increasing overall farm productivity (College Board AP CED).
- 18
What is a common method for reducing soil erosion in sustainable farming?
A common method for reducing soil erosion is the use of contour farming, which involves plowing and planting across the slope of the land (College Board AP CED).
- 19
What is the purpose of sustainable livestock management?
The purpose of sustainable livestock management is to balance animal welfare, environmental health, and economic viability while minimizing the ecological footprint (College Board AP CED).
- 20
How does agroecology contribute to food security?
Agroecology contributes to food security by promoting diverse, resilient farming systems that can adapt to changing environmental conditions and climate variability (College Board AP CED).
- 21
What is the main focus of sustainable aquaculture?
The main focus of sustainable aquaculture is to produce fish and seafood in ways that minimize environmental impact and ensure the health of aquatic ecosystems (College Board AP CED).
- 22
