Textbook Question
Chapter 1, Problem 14CT
The ability of farmers around the world to produce crops such as corn, wheat and rice is often limited by the lack of nitrogen-based fertilizer. How might scientists use Beijerinck’s discovery to increase world supplies of grain?

Miracle RiceRice is a staple food in Asia. In the 1950s, Asia faced food shortages and an impending famine. If you have relatives that lived in Asia during the ’50s and ’60s, they may tell you that due to the rice shortage, many starved and those who were lucky had to supplement their diet with other crops, such as barley. In 1962, an organization focused on research and development of rice called the International Rice Research Institute (IRRI) developed a high-yielding variety of rice by crossing the two types of rice from Indonesia and China. The result was groundbreaking. The new variety called IR8 (India Rice 8) increased its yield as much as 10 times the traditional variety of rice. By the early 1970s, many rice farmers in India, the Philippines, and Vietnam switched to cultivating IR8 rice, making these countries into major rice exporters, preventing a mass famine in Asia, and saving millions of lives.
IRRI is currently in the process of developing a new variety of rice called…
Why is nitrogen used in fertilizer when there's so much N2 in the air
You decide to perform a simple experiment to determine whether nitrogen or phosphorus is a more limiting nutrient in a pond in your backyard. Using a curtain that does not allow water, nutrients, or organisms to pass through, you divide your pond into four equal-sized quadrats (like a pie with four pieces). You randomly apply one of the following treatments to each quadrat: no nutrients (control), nitrogen only, phosphorus only, nitrogen and phosphorus. After 10 days, you measure net primary productivity (NPP) in each quadrat of your pond. You find the following results: Control NPP = 1.2 g C/m2/d; nitrogen only NPP = 1.3 g C/m2/d; phosphorus only NPP = 2.8 g C/m2/d; nitrogen and phosphorus added NPP = 2.8 g C/m2/d. Which is true about nutrient limitation in your pond?
Nitrogen and phosphorus are both limiting nutrients
Nitrogen is the only limiting nutrient
Neither nutrient is limiting
Phosphorus is the only limiting nutrient

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.
