The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Crop rotation would allow the farmer to reduce which of the following?
a) Planting seeds.
b) Watering the fields.
c) The use of manufactured fertilizer.
d) The burning of fossil fuels by farm equipment.

Why would nitrogen-fixing plants be plowed under instead of harvested?
a) To increases usable nitrogen in the soil.
b) To increase water retention.
c) Nitrogen-fixing plants are not a food crop.
d) To decrease bacteria in the soil.
What can be concluded from the graph and the description of the experiment?
A) fertilizer b is more expensive than fertilizer a
B) fertilizer a has a slower growth rate effect on the plants compared to fertilizer b
C) plants using fertilizer a were located further away from windows where sunlight was present
D) during a four week period, the plants with fertilizer b received more water than the plants with fertilizer a

There are two-main types of nitrogen-fixing bacteria: free-living (nonsymbiotic) and mutualistic (symbiotic). Describe the mutualistic relationship between Rhizobium and legumes. What is the advantage of using legumes as a cover crop in agricultural systems? A point of interest is that the nitrogenase enzyme complex is highly sensitive to oxygen. This is a major problem for free-living aerobic species such as cyanobacteria and species of the genera Azotobacter and Beiigrinckia.

- A genetically modified corn crop that is resistant to the herbicide glyphosate ("Round-Up") may contribute to conservation agriculture practices because: O The plants would thrive with less water, so they would not need to be irrigated as frequently. O It is not possible for any other organisms, such as weeds, to develop a resistance to glyphosate. O The plants would be resistant to pests, such as the corn borer, so would not need to be treated with pesticides. O All of these answer choices are correct. Because they could be sprayed with glyphosate, the soil would not require tilling to control weeds.
