This section should detail the plan for implementing the design solution for requirement XXX. In general, this section is software-centric with a focus on software implementation. Pseudo code is appropriate in this section. Links to actual source code are appropriate. Project management items, such as svn branches, timelines and staffing are also appropriate. How do we typeset pseudo code?Changes to cime are limited to sending the nh3 emissions to the atmosphere model. There is no chemistry performed, but future users will be able to use them if ammonia chemistry is enabled.
There are no changes to cime when coupled to biogeochemistry. Turning on coupling allows FAN manure to be used with crops instead of the default manure read in from the parameter file.
Implementation: Add gridded fertilizer data into the surface data with options to mksurfdat for users to generate any resolution required

This section should detail the plan for implementing the design solution for requirement XXX. In general, this section is software-centric with a focus on software implementation. Pseudo code is appropriate in this section. Links to actual source code are appropriate. Project management items, such as svn branches, timelines and staffing are also appropriate. How do we typeset pseudo code?New gridded fertilizer data comes from Mueller et al., (2012) data at a 5 min resolution for 17 crop types. The data was extrapolated to fill in more area to accommodate potentially expanding crop harvest area for future transient land use cases using a poisson grid fill with zonal average. Not all the crop types in the data are included in the model and some crops in ELM are not in the dataset. Missing crops are currently set to zero fertilizer. Potato in the dataset is used for Roots_Tubers in ELM. A mksrf_fert dataset was created for use in the mksurfdat file to generate surface data at user required resolutions. Updates to mksurfdat include a new subroutine to generate nitrogen and phosphorus fertilizer application which will be added to the surface data. The namelist will need to point to the mksrf_fert data, which should be added to the raw data directory.
