Name of the management schedule
The name of the management schedule is a primary key referenced by mgt in landuse.lum. All names in the management.sch file must be unique.
This file is used to schedule management operations.
Management operations can be scheduled by heat units/dates or by Decision Tables.
The structure of the management.sch file is different than that of most other SWAT+ input files. The first line for each management schedule specifies the name of the schedule and the number of scheduled and/or automatic operations. When using scheduled operations, it is followed by one line per operation listing operation-specific data. The operations must be scheduled by date (Heat Unit scheduling must be done using a Decision Table) listed in chronological order. For automatic operations, the names of the Decision Tables in lum.dtl are listed (one name per line). Behind the name of a Decision Table, the user may list the crop(s) used in the Decision Table, which can be useful when the same Decision Table is used for different crop rotations (see xxx in yyy).
The user may use both scheduled operations and Decision Tables for the same land use. If doing so, the names of the DTs should be listed first.

Type of management operation
| Code | Operation | Description |
|---|
pcom | Plant community | This operation initializes the plant community in the HRU |
plnt | Planting/beginning of growing season | This operation initializes the growth of a specific land cover/plant type in the HRU |
harv | Harvest | This operation harvests the portion of the plant designated as yield and removes the yield from the HRU, but allows the plant to continue to grow (e.g. hay cuttings) |
hvkl | Harvest and kill | This operation harvests the portion of the plant designated as yield, removes the yield from the HRU and converts the remaining plant biomass to residue on the soil surface |
kill | Kill | This operation kills the plant and converts the plant biomass to residue on the soil surface |
till | Tillage | This operation mixes the upper soil layers and redistributes the nutrients/chemicals within those layers |
irrm | Scheduled irrigation | This operation applies water to the HRU on the specified day |
fert | Fertilizer application | This operation adds nutrients to the soil in the specified day |
pest | Pesticide application | This operation applies a pesticide to the plant and/or soil on the specified day |
graz | Grazing | This operation removes plant biomass at a specified rate and allows simultaneous application of manure |
burn | Burning | This operation records the biomass, residue and phosphorus that is burned |
swep | Street sweeping | This operation removes sediment and nutrient build-up on impervious areas in the HRU; can only be used when the urban build-up/wash-off routines are activated for the HRU |
skip | Skipping | This operation skips to the end of the year |
