Decision Support System for Precision Irrigation Using Interactive Maps and Multi-agent Concepts

Agriculture is a fundamental pillar in the economy, sustainability and food security. To achive a correct and efficient management of crops, there are strategies, which use the integration of different technologies currently found in engineering, especially electronics and software, to develop methodologies based on measurement, decision support and action on crops. Precision agriculture (PA) is one of those techniques, and it is a strategy used to determine when, where and how to apply the inputs on crops. Geographic Information Systems (GIS) are tools that can be used in PA for the information management of agricultural fields, where, interactive maps allow the characterization of crops, soils and to define prescriptions through Decision Support Systems (DSS). In this work, an useful tool to obtain soil moisture maps of agricultural fields and a water distribution model in USOCHICAMOCHA irrigation district located in Boyaca- Colombia, using a GIS and multi-agent concepts are shown. A negotiation strategy based on the Contract Net protocol is activated when there is a scarcity of water resources, defining priorities for the irrigation distribution in a more efficient manner.
