Abstract: A system and method are provided for managing some or all of an agricultural ecosystem. In one example, the method includes obtaining a current soil moisture level for multiple zones at a geographic location, where each of the zones has been assigned a desired minimum soil moisture level. The zones are ranked in a watering schedule based on a delta between the current soil moisture level and the desired minimum soil moisture level of each zone. For each zone, in the order based on the zone's ranking, at least one valve is opened to deliver water to the zone and closed after watering of the zone is completed. The water may be delivered based on time or volume. If by volume, the volume needed by the zone is calculated.
