The DSSAT crop modeling ecosystem

Description

This chapter describes the DSSAT Crop Modeling ecosystem, its history, creation of multiple crop models, and tools for data preparation, analysis and applications. The chapter provides an overview of the structure and science of the crop simulation models that are included in DSSAT, as well as the tools and utilities for weather, soil, experimental and observational data entry, and crop model calibration and evaluation. It also reviews the range of applications.
