RNG from Energy Crops

I am examining an AD process that will produce RNG from purpose grown energy crops. I intend on modelling this in the Manure/Grass RNG pathway and will input the feedstock in the corn/soy beans/canola/wheat category. Obviously I will turn off any avoided emissions.

Does this pathway automatically take into account driving the tractor to harvest the crops, fertilizer used to grow them and any land use changes associated with the energy crops? Or are these factors that I should input manually somewhere in the model?

Thanks,
Graham
