The text explains how computers help to simplify calculations and other duties related to the field. The book's 21 chapters revolve around the relationship of computers, agriculture, and the environment. The majority of the chapters talks about the different simulation controls that the computer can do. Controls include climate control, greenhouse control, greenhouse climate feedback/feed-forward control (GCFFC) control, glasshouse control, crop drying control, sulfur dioxide control, retort control, animal control, broiler-house ventilation control, and poultry-house control. Other topics related to computers and agriculture are also discussed, such as monitoring rainfall interception, grain drying, monitoring techniques for ammonia, and various techniques for remote monitoring. The text covers a wide range of topics in the mentioned fields, and can therefore serve as an excellent reference for students or professors in the field of agriculture.
