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
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

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
kill
Plant in the plant community (plant.ini) to be killed
