Sustainable Agriculture and Environmental Systems Quiz

What is the definition of sustainable agriculture?

• Agriculture that relies heavily on synthetic pesticides and fertilizers for crop production.

• Agriculture that focuses on maximizing crop yields without considering the impact on the environment.

• Agriculture that prioritizes industrial farming methods over traditional techniques.

• Agriculture that fulfills the need for food and fiber while enhancing the quality of the soil, minimizing the use of nonrenewable resources, and allowing economic viability for the farmer.

What is the primary purpose of integrated pest management (IPM)?

• To rely solely on natural sources for pest control.

• To eliminate pests completely from agricultural settings.

• To maximize the use of synthetic pesticides for pest control.

• To minimize pesticide inputs and manage pest damage with the least possible hazard to people, property, and the environment.

What is the main advantage of hydroponic agriculture over traditional irrigation?

• Is more suitable for large-scale crop production than traditional irrigation.

• Is more cost-effective and requires less labor than traditional irrigation.

• Requires little or no pesticide use and uses up to 95 percent less water than traditional irrigation.

• Is less environmentally friendly than traditional irrigation methods.

What is the purpose of crop rotation in sustainable agriculture?

• To improve soil health by planting different crops sequentially on the same plot of land.

• To maximize the yield of a single crop by planting it in the same place every year.

• To reduce the need for irrigation by planting drought-resistant crops.

• To eliminate the need for synthetic fertilizers and pesticides.

What is the primary goal of agroforestry?

• To intentionally, intensively, and interactively integrate trees and vegetables for sustainable agriculture.

• To reduce the use of water for agriculture by planting crops in a greenhouse environment.

• To maximize the production of a single crop by planting it in a forested area.

• To eliminate the need for crop rotation by planting multiple crops in the same field.

What is the main characteristic of no-till agriculture?

• Farmers focus on maximizing crop yields without considering the impact on the environment.

• Farmers rely on traditional irrigation methods for crop production.

• Farmers use excessive amounts of synthetic pesticides and fertilizers for crop production.

• Farmers do not turn the soil between seasons as a means of reducing topsoil erosion.

What is the primary purpose of rotational grazing in livestock farming?

• To maximize the use of synthetic pesticides for pest control in livestock farming.

• To promote healthy regrowth of pastures and decrease erosion by grazing the herd on only one portion of land at a time.

• To reduce the cost of livestock farming by minimizing the use of land for grazing.

• To eliminate the need for pasture rotation by allowing the herd to graze freely.

What is the main advantage of free-range farming over confined animal feeding operations (CAFOs)?

• Free-range farming results in higher yields and better quality meat than CAFOs.

• Free-range animals require treatment and disposal of massive quantities of manure.

• Free-range farming requires less land and is more cost-effective than CAFOs.

• Free-range animals are less likely to spread disease and the use of antibiotics and other medications can be reduced or eliminated.

What is the primary purpose of contour farming?

• To reduce soil erosion by farming with row patterns that run nearly level around the hill.

• To maximize crop yields by farming up and down the hill to ensure even distribution of water and nutrients.

• To eliminate the need for crop rotation by planting different crops sequentially on the same plot of land.

• To promote the use of synthetic pesticides and fertilizers for crop production.

What is the main goal of the Sustainable Fisheries Act passed in 1996?

• To eliminate the need for fishery management plans and international agreements.

• To maximize the catch of fish in a season without considering the impact on fish populations.

• To shift fisheries management from a focus on economic sustainability to a species-sustainability approach.

• To promote the use of synthetic pesticides and fertilizers in fish farming.
