Why not try an experiment to gradually increase the amount of N fertiliser to 50kg? Is the yield showing an inflection point (ie a minimum amount), or is the response linear?
I am following this tutorial: https://www.apsim.info/support/apsim-training-manuals/apsim-training-simlesa/multiple-season-maize-simulations/ Therefore, should be working.
Those simulations from the simlesa days used an older version of the maize model (7.5 iirc). The current maize model (7.10) has a different N demand method based on SLN and not a static concentration. The thresholds / responses most likely are not the same.
I see... Thanks
Maize_0n_10year.docx Hey, I am using APSIM classic to run the Maize_10year simulation and I get 0 yield. I have re-done the simulation 4 times already, and this is always the result. Can you help with what is wrong? If I change topdressing to 50 for next simulation it works fine.
Also, is these tutorials going to be available for the new generation APSIM? Because the more advanced simulations are all in classic.
Kind regards, Isis
