Abstract: An alfalfa valve telemetry system for regulating irrigation fluid to an irrigation-dependent field provides an alfalfa valve that operates over an opening to a fluid supply pipe in a field, so as to selectively discharge fluid to the field. The alfalfa valve telemetry system provides a telemetry-controlled valve actuation assembly that axially or pivotally displaces the alfalfa valve between an open position and a closed position over the opening in the pipe. A valve actuation assembly displaces the lid, axially, or pivotally, over the opening of the pipe. A mounting portion anchors the valve actuation assembly to the pipe. Environmental sensors and fluid sensors in the field communicate data signals with a primary controller that controls the valve actuation assembly. The position of the alfalfa valve is based upon the data signals received from the sensors, indicating fluid levels, fluid flow rate, and environmental conditions on and near the field.

Abstract: An automated irrigation gate system and method for regulating water levels in irrigation channels automates control of water through an irrigation channel based upon water levels, water flow rate, and ambient environmental conditions in the irrigation channel and an adjacent agricultural region. The system comprises at least one irrigation regulation device operationally attached to the irrigation channel. The irrigation regulation device regulates fluid flow through a channel opening in the irrigation channel through use of a gate. A fluid sensor monitors the level of fluid in the channel and an adjacent agricultural region. The fluid sensor also monitors the flow rate of the fluid flowing from the channel to the region. An environmental sensor monitors environmental conditions ambient to the region. A control portion comprises a processor that calculates the data to selectively displace the gate between an open position and a closed position relative to channel opening.
