Describe the jоurney оf а N аtоm thаt travels through a cropping system. (7 pts) Starting as N2 gas, it first interacts with a crop that eventually dies and decomposes, resulting in a transformation to NH4+. Describe the two processes involved in the transformation and the main group of organisms involved in each of these transformations. (11 pts) As a NH4+ molecule, this N atom can now be affected by multiple processes. Describe the microbial process that convert it to NO3- and how one controlling factor affects that process, in addition to two other important products of that reaction - one is a gas, one is not. Alternatively, NH4+ may be affected by three other processes (excluding crop uptake) – describe two of these processes and how one controlling factor affects each process. (7 pts) As a NO3- molecule, the N atom now faces two opposite paths (excluding crop uptake). Describe these two processes, including how one controlling factor affects each process, and a potential environmental impact for each of these two processes.
