Supply chains for French fries and pasta sauce are surprisingly resilient to climate change, according to the predictions of a new study.The study’s authors made their predictions using an innovative modeling […]
This Special Issue of The Journal of Agricultural Science is dedicated to the iCROPM 2020 Symposium. It includes six papers that are based on both oral and poster presentations from the symposium, including the final keynote presentation. Read the Editorial:iCROPM 2020: Crop Modeling for the Futureby, Gerrit Hoogenboom, Eric Justes, Christophe Pradal, Marie Launay, Senthold […]
We recently published a chapter entitled “The DSSAT crop modeling ecosystem” in the book “Advances in Crop Modeling for a Sustainable Agriculture.” This chapter provides a brief history of DSSAT, an overview of its functionality and applications, and up-to-date information on the status of the DSSAT Cropping System Model (CSM) and the DSSAT tools, utilities […]
This collection summarises key advances in crop modelling, with a focus on developing the next generation of crop and whole-farm models to improve decision making and support for farmers. Chapters in Part 1 review advances in modelling individual components of agricultural systems, such as plant responses to environmental conditions, crop growth stage prediction, nutrient and […]
There are 3 methods of dealing with soil layers in DSSAT, controlled by MESOL in simulation controls: MESOL = 1: old DSSAT method of forcing soil layer thicknesses to be 5, 10, 15, 15, 15, 30, 30, 30, 60, 60, 60 cm thick. Soil properties are blended when user input layers are forced to standard […]
The HarvestChoice Project at IFPRI, in collaboration with IRI at Columbia University and Michigan State University, published a working paper on the development of a new, global high-resolution soil profile database for DSSAT. The dataset is freely available at IFPRI’s Dataverse at http://dx.doi.org/10.7910/DVN/1PEEY0.
Biophysical models are commonly used in ecosystem impact assessment studies at different temporal and spatial scales, and their results implicate decisions on the overall system at multiple levels—from micro-scale natural resource management to country- or regional-scale policy decisions. In agricultural systems, soil data is often key for understanding the current status of the ecosystem and […]
February 9, 2012, marked 500th download of the WISE 1.1 Global Soil Profile Database in DSSAT format. To celebrate, we created a little Wordle using the users’ responses to our question on the intended use of the dataset.
