This means Apsim is unable to find certain crop properties in the soil. You will see the following:Р”В¬annot find soil water information for crop 'chickpea' You will notice it runs very quickly, but errors were found. The last three sowing criteria mean that for a crop to sow within the given window at least 15mm of rain must have fallen in the last three days and there must be a minimum of 200mm soil water available.Р”РЋ0.

We can then try different management strategies to see which one would have worked best under the past 10 years weather scenarios.Р”РЋ. But what if you wanted to work out what the best strategy would be for the current year using weather scenarios from the past 40 years? To do this we could create 40 different simulations all with the same starting conditions but a different weather file (which would be a lot of work), or we could run the same simulation over 40 years and just reset the starting conditions each year (much simpler). This is useful if you are interested in seeing the degradation or improvement of the soil over a long time period. longer than one year), the end of one yearsРІР‚в„ў simulation becomes the starting point of the next year. The weather will be different each year but the soil starting conditions will be the same.Р”В«y default, in long term simulations (i.e. We will compare two sowing rate strategies for these conditions with the goal of maximising yield. In this exercise you will use sowing rules to plant Chickpea crops and observe yield probabilities for a 40 year period given a half full soil moisture profile at sowing.
