GAP Conservation & Sustainability 2

Question 1

Which cover crop practice best reduces soil erosion between growing seasons on a GAP-certified farm?

Accepted Answer

Planting winter rye or cereal crops

Answer

Winter rye and other cereal cover crops establish quickly to hold soil in place and reduce erosion during the off-season.

Question 2

A farm's nutrient management plan should be based primarily on which of the following?

Accepted Answer

Soil and tissue test results

Answer

Soil and tissue test results provide the scientific basis for accurate nutrient applications, preventing over-application and reducing runoff risk.

Question 3

What is the primary purpose of a riparian buffer on a GAP-certified farm?

Accepted Answer

Filtering runoff before it enters waterways

Answer

Riparian buffers are vegetated strips along waterways that filter sediment, nutrients, and pathogens from agricultural runoff.

Question 4

Under GAP principles, integrated pest management (IPM) prioritizes which intervention first?

Accepted Answer

Biological and cultural controls before chemicals

Answer

IPM follows a hierarchy that begins with prevention and biological controls, using chemical pesticides only when other methods are insufficient.

Question 5

Which water conservation technique is most efficient for irrigating vegetable crops under GAP standards?

Accepted Answer

Drip or micro-irrigation

Answer

Drip irrigation delivers water directly to the root zone, dramatically reducing evaporation and runoff compared to other methods.
