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 two main groups of organisms involved in this part of the journey. (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 two controlling factors of that process. Describe two other important products (or byproducts) of that reaction - one is a gas, the other is not. Alternatively, NH4+ may be affected by three other processes (excluding crop uptake) – describe these three processes and one controlling factor for each. (7 pts) As a NO3- molecule, the N atom now faces two main opposite paths (excluding crop uptake), both of which result in N loss from the system. Describe these two processes, including one controlling factor for each process, and a potential environmental impact for each process.
