IMPORTANT NOTE: It is highly recommended that you upgrade your APSIM Next Gen version to at least version 2023.2.7164.0 or later.
In this exercise you will observe the growth of a crop over a single season. You will learn a bit more about how to use APSIM to do a ‘what-if’ experiment with fertiliser rates. These skills can not only be used to experiment with sowing fertiliser rates but also variables such as:
open an example menu item
Dalby.met is the selected met file under the weather node.
1/01/1989 - 31/12/1989 under the
initial values column of both
SowingRule management node.
Amount of fertiliser to be applied (kg/ha) to
Wheat yield time series graph.
Experiment node to the
Simulations node at the top of the simulations tree.
Experiment node will be added to the bottom of the tree, hold
ctrl key and press
up arrow several times until it is directly below the
Factors node to this experiment.
Factor node to the
Wheat simulation to the experiment as a child node.
Wheat simulation node onto the
Wheat simulation that is not a child of the experiment node.
[SowingFertiliser].Script.Amount = 0 to 60 step 30
Experiment node, you can see 3 differing amounts of sowing fertiliser.
