Abstract: Decision Support Systems are computerized systems, which include models and databases and they are used in decision making. It has been applied to solve variety of agricultural problems. Process of taking a decision is so complex as there are several factors affecting entire farming process. The environmental data plays a vital role in agriculture decision, which changes at a rapid rate. Keeping these data updated can be done by using a Service Oriented Approach (SOA). At present, irrigation decision-making systems applied to the field of agriculture were mostly aimed at a given area and specific crops. It was difficult to be applied in different areas and different crops. In this paper, a precision irrigation decision-making system has done something to solve this problem. This paper presents that SOA used to get precise irrigation schedule for different crops. In addition, it shows a good reflection and wide use.
