The DSSAT and MWCropDSS 2018 International Training Program entitled “Efficient and precision agricultural resource utilization under changes with simulation models and GIS” will be held from August 27 through September 1, 2018 at Chiang Mai University in Chiang Mai, Thailand. This workshop is jointly presented by Chiang Mai University, The University of Florida, the DSSAT Foundation, The Thailand Research Fund (TRF), Geo-Informatics and Space Technology Development Agency (GISTDA), and the Rice Department of Thailand. The overall goal of the workshop is to gain a better understanding of simulation models in predicting relationships of agricultural resources, i.e., water and nitrogen under various weather and climate conditions, on crop phenology and growth. Each participant will receive the DSSAT v4.7 and MWCropDSS applications for Windows and the book ‘Understanding Options for Agricultural Production’. The registration fee is $1,000 if you register by July 31 and $1,500 if you register after July 31, 2018.
