Energy use in Swedish agriculture
I have done research on the use of energy in agriculture in Sweden. The energy use can be divided into two parts, direct and indirect. The direct energy is the energy used on farms, while the indirect energy is the energy used for producing purchased inputs such as fertilisers.

Direct and indirect use of energy in Swedish agriculture. The total use of energy in Swedish agriculture is estimated to be 9.2 TWh (33 PJ) per year. Diesel and nitrogen fertilisers together represent about 51% of the total energy (from my PhD thesis, 2009 see publication list).

The largest direct energy use is the use of fossil diesel, primarily for tractor fuel. Read more about biofuel for tractors
The largest indirect energy use is the production of fertilisers. Read more about nitrogen fertilisers
