My modification to source code has effects for BGC run but no effects for SP run

Happy new year! Recently I was doing some modifications to the irrigation module in CLM. Here I want to have something special for rice paddies, thus I set the condition as (col%itype(c)==(200+cft_lb+47)), as the 48th cft is irrigated rice. However, in BGC simulations, it works but in SP, it does not work. I am so confused by this result.

To use the full set of crops you need to use the BGC model and turn on the use_crop namelist option to use all prognostic crop types. For SP mode (and when BGC is on, but use_crop is off) it integrates specific crops up into generic crop types. So what you are seeing is completely expected.

For the details it also matters what specific version you are using. But, the above general statement is going to apply for any recent versions.

Hi Eric,
I see. Thanks for your explanation.
Best,
