Q: A watershed is the land area from which water drains to …
- a lake
- a river
- the ocean
- the same point
A: the same point

Q: Water quality impacts to watersheds include which of the following?
- industrial waste spills
- nonpoint source pollution
- soil erosion and sedimentation
- all of the above
A: all of the above

Q: The Environmental Protection Agency identifies what as the number one water pollutant?
- agricultural chemicals
- agricultural animal wastes
- sediment
- litter
A: sediment

Q: Agriculture accounts for what percentage of the nation’s consumptive water use?
- 33%
- 59%
- 72%
- 80%
A: 80%

Q: Marginal lands are those not cropped because of what reasons (check all that apply)?
- they are less economically productive than currently cultivated land
- more pesticide and nutrient use is required to gain productivity
- there is greater potential for erosion and nutrient runoff
- they are best suited to other uses
A: they are less economically productive than currently cultivated land; more pesticide and nutrient use is required to gain productivity; there is greater potential for erosion and nutrient runoff; they are best suited to other uses

Q: Which of the following is not likely to happen if more land is needed to grow corn for corn-grain ethanol production?
- marginal land will be brought into production
- land in CRP will increase
- crop rotations will change to support bioenergy demand
- increases in the use of fertilizers and pesticides
- ecological intensification of crop production
A: land in CRP will increase

Q: Converting land from CRP to crop production requires careful planning to achieve these goals (check all that apply)?
- avoid violating CRP contracts by killing grass too early
- provide sufficient nutrients to the crop in the first year after CRP
- remove all grass cover so soil can be worked more easily
- provide a long-term goal of crop productivity and soil and water protection
A: avoid violating CRP contracts by killing grass too early; provide sufficient nutrients to the crop in the first year after CRP; provide a long-term goal of crop productivity and soil and water protection

Q: Where possible, planting soybeans the first year after CRP has which of the following advantages.
- can be planted later in spring, allowing for one more application of herbicide
- seed soil contact is not critical since soybeans compensate well for skips
- little need for nitrogen application if soybeans are inoculated well
- easy to plant no-till
- all of the above
A: all of the above

Q: Which of the following in not a goal of Ecological Intensification?
- producing grain crops nearer their genetic potential yield
- increasing food, feed and fuel supply
- reducing environmental impacts of cultivating marginal lands
- avoiding use of modern technologies
- preserving habitat
A: avoiding use of modern technologies

Q: The need for Ecological Intensification is driven by which of the following
- the increasing global demand for grain
- the demand for biofuels
- the desire to protect the environment
- all of the above
A: all of the above
