Does this account for the massive amount of energy we 'cheat' out of natural gas derived fertilizer? If we eliminate natural gas, the energy costs of fertilizer

  Yes, it includes the energy used in making fertilizer. It also includes all the fuel used on farms. Here's a link for the numbers from 2014. https://www.ers.usda.gov/amber-waves/2017/januaryfebruary/energy-consumption-and-production-in-agriculture/ https://www.ers.usda.gov/amber-waves/2017/januaryfebruary/en... In that year, ag used 1.74% of US energy consumption. 29% of that was for fertilizer. As I said, the absolute amount of energy used in farming is really rather small, even for "energy intensive" agriculture. That's because the ag sector is such a small part of the US economy (< 1% of GDP).
