Modeling soil and plant phosphorus within DSSAT

Ecological Modelling, 2010
Abstract The crop models in the Decision Support System for Agrotechnology Transfer (DSSAT) have served worldwide as a research tool for improving predictions of relationships between soil and plant nitrogen (N) and crop yield. However, without a phosphorus (P) simulation option, the applicability of the DSSAT crop models in P-deficient environments ...

Estimation of Winter Wheat Production Potential Based on Remotely-Sensed Imagery and Process-Based Model Simulations

Remote Sensing, 2020
Crop production potential is an index used to evaluate crop productivity capacity in one region. The spatial production potential can help give the maximum value of crop yield and visually clarify the prospects of agricultural development.

Evaluation of DSSAT model (CERES rice) on rice production: A review [PDF]

International Journal of Chemical Studies, 2020
Rice is the staple food for over half of the world population. Crop models potentially offer a means to readily explore management options to increase yield, and to determine trade-off between yield, resource-use efficiency and environmental outcomes. This paper reviews the performance of CERES-Rice model in different regions of the world in relation ...

gym-DSSAT: a crop model turned into a Reinforcement Learning environment

, 2022
La résolution d’un problème de déecision séquentielle en conditions réelles s’appuie très souvent sur l’utilisation d’un simulateur qui reproduit ces conditions réelles. Nous introduisons un nouvel environnement pour l’apprentissage par renforcement (AR) qui propose des tâches d’apprentissage réalistes pour la conduite de cultures.
