Agriculture and Environment Sustainable Agriculture & Environmental Conservation 2 — Questions and Answers
Question 1: What is the primary purpose of riparian buffer strips in agricultural landscapes?
- Providing additional cropland along waterways
- Filtering agricultural runoff and protecting stream banks from erosion (Correct answer)
- Creating habitat for pest insects
- Increasing irrigation efficiency
Correct answer: Filtering agricultural runoff and protecting stream banks from erosion
Riparian buffers are vegetated strips along waterways that filter sediment, nutrients, and pesticides from runoff before they reach streams.
Question 2: Which sustainable farming certification is administered by the USDA and prohibits synthetic pesticides and fertilizers?
- Fair Trade Certified
- USDA Organic Certification (Correct answer)
- Rainforest Alliance Certified
- Non-GMO Project Verified
Correct answer: USDA Organic Certification
USDA Organic Certification prohibits synthetic pesticides, fertilizers, and GMOs, requiring adherence to National Organic Program standards.
Question 3: What is 'precision agriculture' and how does it support sustainability?
- Farming small plots by hand
- Using GPS, sensors, and data to apply inputs precisely where needed, reducing waste (Correct answer)
- Growing only precision-bred crop varieties
- Farming using traditional heritage methods
Correct answer: Using GPS, sensors, and data to apply inputs precisely where needed, reducing waste
Precision agriculture uses technology to optimize input application, reducing excess fertilizer and pesticide use while maintaining yields and minimizing environmental impact.
Question 4: What is eutrophication, and what agricultural practice primarily causes it?
- Soil carbon sequestration caused by cover cropping
- Excessive algae growth in water bodies caused by nutrient runoff from fertilized fields (Correct answer)
- Soil acidification caused by acid rain
- Biodiversity loss caused by monoculture farming
Correct answer: Excessive algae growth in water bodies caused by nutrient runoff from fertilized fields
Eutrophication occurs when excess nitrogen and phosphorus from agricultural runoff enter water bodies, triggering algae blooms that deplete oxygen and harm aquatic life.
Question 5: Which federal program helps farmers implement conservation practices by providing technical and financial assistance?
- Supplemental Nutrition Assistance Program (SNAP)
- Environmental Quality Incentives Program (EQIP) (Correct answer)
- Federal Crop Insurance Program
- Market Access Program (MAP)
Correct answer: Environmental Quality Incentives Program (EQIP)
EQIP, administered by NRCS, provides financial and technical assistance to agricultural producers to implement conservation practices that address natural resource concerns.
Question 6: What is carbon sequestration in agriculture?
- Releasing carbon from soil through tillage
- Capturing and storing atmospheric carbon in soil and plant biomass through farming practices (Correct answer)
- Burning crop residues to reduce carbon in fields
- Measuring carbon emissions from farm equipment
Correct answer: Capturing and storing atmospheric carbon in soil and plant biomass through farming practices
Agricultural carbon sequestration stores atmospheric CO2 in soil organic matter and plant biomass through practices like cover cropping, no-till, and agroforestry.
