Contrast soil tests that measure the “total” versus “available” concentration of a nutrient. What do we mean by total and available. How do we determine what the “available conc” corresponds to (in terms of plant performance)? 9. Contrast organic and mineral (inorganic) fertilizers. What are some of the farm management implications of these differences? 10. What are the major types of organic fertilizers? What determines the availability of the nutrients in these fertilizers to plants? How do the concentrations of different nutrients in organic fertilizers compare to those in inorganic (mineral) fertilizers? List two advantages of synthetic and two advantages of organic fertilizers. 11. What is integrated soil fertility management? 12. Why might promoting immobilization of nitrogen be a good thing for the environment? 13. Discuss some approaches to increase nutrient use efficiency and reduce nutrient “loss” in cropping systems. 14. How does timing and spatial placement of fertilizer play a role in crop nutrient efficiency (and reducing losses to environment)? What are some strategies/technologies to help with this? 15. How can farmers use less and leak less fertilizer? 16. What are two global environmental consequences of fertilizer use?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
