Plant population
Age of plant at start of simulation
Initial residue cover
Number of plants in the community
This number must be consistent with the number of plants listed for the community.
Initial Leaf Area Index
This variable is required for plants that are growing at the beginning of the simulation (lc_status = y).
Initial fraction of plant heat units accumulated
This variable is required for plants that are growing at the beginning of the simulation (lc_status = y).
Plant community name
The name of the plant community is a primary key referenced by plnt_com in landuse.lum. All names in the plant.ini file must be unique.
Plant name as in plant database
The plant name is a foreign key referencing the primary key name in plants.plt.
Initial plant biomass
This variable is required for plants that are growing at the beginning of the simulation (lc_status = y).
Land cover status at start of simulation

n | Plant not growing |
y | Plant growing |
This file stores information about the plants growing in a plant community.
A plant community can consist of plants growing at the same time or plants growing in rotation.
The structure of the file plant.ini is different than that of most other SWAT+ input files. The first line for each plant community specifies how many plants there are in the community and what the initial year of the rotation is. It is followed by one line per plant in the community.
