Which of the following is the correct order of soil particles in order of increasing size?

Clay—silt—sand

A farmer grows several crops on a farm that has mostly shallow, sandy soil. Which of the following irrigation methods would be the best suited for this farm?

Drip irrigation

Which of the following statements correctly pairs an irrigation method with an advantage or disadvantage?

Flood irrigation is often used in agricultural fields, however, it increases surface erosion and salinization of the soil.

Which of the following irrigation methods is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight?

Furrow irrigation

Which of the following best describes a disadvantage of using genetically engineered crops over crops that are not genetically modified?

Genetically engineered plants can decrease the genetic diversity of the crop.

Based on the data in the graph, which of the following proposed solutions would have the greatest effect on reducing global water withdrawals?

Government grants to assist farmers with the up-front installation costs of drip irrigation systems.

Which of the following is the best illustration of the pesticide treadmill?

Increased use of pesticides to eradicate genetically resistant pests

Which of the following statements best identifies the author's perspective in terms of government funding for future agricultural research?

More funding is continually needed because the agricultural research programs have never been completely financially supported.

Soil conservation

No till farming which disturbs the soil minimally keeping it intact from wind and water erosion Contour farming where the farming is gently swiped to slow water runoff

Which of the following techniques is a realistic solution for farmers to decrease the amount of fertilizer and sediment runoff into aquatic ecosystems?

Practicing crop rotation

Based on the data in the table above, which of the following samples would be the most prone to becoming waterlogged?

Sample D

Which of the following soils is best suited to grow corn?

Sandy loam because it has large amounts of sand and less than 20%20% clay.

Which of the following is the best method for preventing soil erosion in an agricultural area?

Terrace farming

Which of the following is the dependent variable in the study?

The density of a species of algae growing along the bottom of the river

Which of the following statements is best supported by the data in the table?

The greatest effect of integrated pest management was seen in lower levels of endosulfan in both tomatoes and cucumbers.

Which of the following statements best identifies the author's perspective in terms of utilizing science technology for future agricultural advances?

The only way to meet the global demand for more food is to fully utilize new science technologies to advance agriculture.

Which of the following best describes the independent variable in this research design?

The sample of material chosen as the potential container material is the variable being tested, so it is the independent variable.

Which of the following statements best explains the relationship shown on the graph?

The use of glyphosate has selected for herbicide resistance in weed populations.

Which of the following is the most likely result from clearing mature, forested land and converting it into agricultural land that would be used for cattle grazing?

There will be a reduction in the uptake of atmospheric carbon dioxide.

Which of the following claims would be the best solution to the pest problem, based on the data in the graph?

Use of Integrated Pest Management techniques is the most successful method because the sources for food, water, and shelter for pests are disrupted, leading to a reduced number of pests in the area.

A farm is experiencing extensive crop loss due to high rains causing overly saturated soils. Which of the following approaches would best help the farmer alleviate the problem?

amending the soil with sand to increase the permeability of the soil

A major environmental problem caused by using the agricultural practice of tilling is

eutrophication from excessive fertilizer use

An advantage of using synthetic fertilizer instead of organic fertilizer is that

synthetic fertilizer can provide more targeted macronutrients to the crops
