Dear Respected sir / friends

I am a Master student in the field of Integrated Water Resources Management with specialization water supply and drainage engg.at Asian Institute of Technology, Thailand. I am doing thesis on nitrate leaching from tropical paddy field in Thailand. I want to use DSSAT3.5 models,for rice (Suphanburi1) crop, to calculate nitrate leaching from paddy field. I made the experiment file , soil file and weather file in DSSAT3.5 model. I input all  measured data including irrigation date , method(IR003 = flood in mm), and amount.  I could success to do simulation.But in the output file , the cumulative irrigation and flooding depth is zero, in reality which can't exist. I want know that how can I solve this problem.

I am waiting your help.

Yours Sincerely
