Assuming that you can still feed the numbers required. OTOH
if you don't use all the chemferts that require energy to
manufacture then you are saving some at that end.
You probably already know that nitrogen production uses natural gas as
its feedstock...
Yes. The Haber process produces greenhouse gases as a by-product and it is
a factor in the overall energy economy as that natural gas could be used
(for example) to generate electric power or to run cars. The process can
also use other hydrocarbons or none at all.
The haber process can be run from hydrogen produced electrolytically which
doesn't generate GHG if you get your electricity from renewable sources but
that would increase the price of fertiliser at current renewable electricity
prices.
