In precision agriculture are used robots and different software to relieve decision making for human.  Our approach is to use multiagent system advantages to make decision making process autonomous. For that we need to use improved agroXML standard to transmit messages between agents. Improved agroXML standard includes information for each agent deliberation and decision making processes. For message transmitting are used wireless environment. One of the agent type is mobile robot and another agent type is database where is stored crop field environmental and dimensional information for mobile robotic agent. These agents leader is complex system where is made deliberation and learning processes. As result of research paper is improved agroXML schema for communication between precision agriculture complex system agents.
