Abstract

The HERMES model is an agroecosystem model designed to operate under data-limited conditions of agricultural practice. The fundamentals of the model components are given, and the data requirements, data structure, and user interface are described. A general guideline for how the model can be calibrated is presented, and examples demonstrate how the model can be calibrated and validated with field experimental data. The use of the model to derive fertilizer recommendations for winter wheat (Triticum aestivum L.) is described, and examples using spatially variable data demonstrate the sensitivity of the model and the uncertainty of predictions due to annual weather variability.
