Disclosed here are systems and methods for controlling an irrigation system using a two-wire electrical path. The system includes a controller, decoders, and sensors all connected by a two-wire wired connection. The controller controls the decoders and provides parameters to the sensors in an open-loop operation mode. The sensors may control one or more of the decoders in a closed-loop operation mode. The system may further operate in a hybrid operation mode providing both open- and closed-loop operation. The various components of the system communicate using a power line communication protocol which places data on a frequency or bandwidth separate from the power signal.

A process for batch processing by-product water to obtain a batch of beneficial use water for application to an targeted area of soil with determined moisture and chemical characteristic to change that soil characteristic to a desired soil characteristic includes the steps of measuring the moisture and chemical composition of the targeted area of soil; determining a desired soil characteristic that will grow selected vegetation; defining a chemical composition of a batch water to be applied to the soil to obtain the desired composition; processing a batch of by-product water in accordance with the defined composition; applying the batch of processed water to the targeted area of soil; measuring the moisture and chemical composition of the soil after application; repeating the process until desired composition is achieved or the vegetation growth is completed.

A system and method of irrigation control calculates a predicted soil moisture value based that is compared to low moisture threshold. If the predicted soil moisture value is a value below the low moisture threshold value, the next irrigation cycle or scheduled irrigation operation is allowed to proceed or otherwise activated. The predicted soil moisture value may be calculated by adjusting a current soil moisture value by a historical adjustment factor based on negative net changes in soil moisture values.

An irrigation system may be implemented to provide location data with respect to one or more autonomous devices. Irrigation hardware, such as moisture sensors, with known locations on a property, may be provided with field sensing to accurately determine the location of an autonomous device with respect to the known location of the irrigation hardware. Existing hardware, such as moisture sensors, may be retrofitted or provided with field sensing electronics to determine the location of autonomous devices.
