Description : A soil plant atmosphere system model
Daisy is a mechanistic simulation model of the physical and biological
processes in an agricultural field. It traces the fate of water, energy,
carbon, nitrogen, and pesticides, both above and below ground. The model
is able to predict production, environmental impact in the form of
leaching, and change in soil (carbon) quality over time. Another common
use is as an upper boundary for a groundwater model.
The input to Daisy is daily or hourly weather data (at least
precipitation, global radiation, and temperature, much more can be used
if available), management information (sow/harvest, tillage operations,
as well as data and amounts of irrigation, fertilizer and pesticide
applications), and finally soil quality (texture, humus content).
The timescale go from hourly fluxes to changes in soil carbon pools over
centuries.
The default one dimensional Daisy transport model assumes homogeneous
fields, with no significant horizontal transport. An optional two
dimensional transport model exists is included, and has been used for
simulating row crops and drain pipes. To model larger areas, Daisy
should be coupled with a GIS system.
The input to Daisy is through text files. Output is also text files,
with the exception of simple progress messages during the simulation.
The code can be accesses from a command line utility, a simple GUI (Qt
based), or from another program through C, C++, C# or OpenMI interfaces.
Daisy is developed by members of the Agrohydrology group at Department
of Basic Sciences and Environment, Faculty of Life Sciences, University
of Copenhagen. The primary responsible scientist is Søren Hansen.
