For ammonia production, hydrogen source is methane which is available in natural gas 90-96% approx.

For cracking of methane, steam reforming process is used.

The Reaction of steam and methane at temp 750 degrees C using nickel catalyst gives hydrogen and carbon monoxide.

This is not cracking its reforming. Cracking is a different process and gives H2, CO, CO2.
