GAP Environmental Impact Assessment 3

Question 1

Which type of erosion assessment method involves measuring the amount of soil lost from a field using established rainfall and soil parameters?

Accepted Answer

Revised Universal Soil Loss Equation (RUSLE)

Answer

RUSLE is a widely used erosion prediction model that estimates average annual soil loss based on rainfall, soil erodibility, slope, cover, and conservation practices.

Question 2

Under GAP certification, which action demonstrates proper environmental stewardship when applying pesticides near waterways?

Accepted Answer

Maintaining a pesticide-free buffer zone adjacent to the water body

Answer

Maintaining buffer zones near water bodies prevents pesticide drift and runoff from contaminating aquatic ecosystems, which is a core GAP environmental requirement.

Question 3

What is 'integrated nutrient management' in the context of environmental impact?

Accepted Answer

Using a combination of organic and synthetic fertilizers to meet crop needs while minimizing environmental losses

Answer

Integrated nutrient management balances crop nutrition needs with environmental protection by combining organic amendments and synthetic fertilizers at optimum rates.

Question 4

Which on-farm practice most directly reduces the risk of groundwater contamination from agrichemicals?

Accepted Answer

Using precision application technology to target specific areas

Answer

Precision application technology reduces over-application by targeting only areas that need treatment, limiting excess chemical movement into groundwater.

Question 5

What is the environmental significance of maintaining a diverse crop rotation system?

Accepted Answer

Reduces pest pressure, improves soil health, and decreases reliance on chemical inputs

Answer

Diverse crop rotation breaks pest and disease cycles, builds soil organic matter, and reduces the need for synthetic pesticides and fertilizers.
