OverviewGiving a full description of the simulation techniques used in the greenhouse industry, this text includes information on different environments from mulching to greenhouses. Another important topic discussed at length is the relationship between plants and the environment. An emphasis is put on the relationship between quantitative phenomena and qualitative analyses. Most of the phenomena involved are non-linear and non-steady-state. In this second edition we describe these phenomena with an approach called System Dynamics and mathematical models developed in the simulation languages MATLAB and SIMULINK. These models can be easily adapted to the specific requirements of the readers, and the environments in which they work. In general, the subjects covered in this book should be relevant to graduate students, scientists and researchers in the agricultural and biological sciences.
