Data requirements for agricultural systems research and applications on agrotechnology information. However, some elements of the required daily weather data, especially global radiation, are not always available. In such instances, substitutes such as hours of sunshine or a weather generator can be used..Data that describe the biophysical characteristics of a syste

It will also be possible to make more effective use of conventional biophysical models (e.g., crop growth, land evaluation, and soil-erosion models) to estimate the likely consequences of research.
