A manifold for a hydroponic system comprises a main body, an inlet port, an outlet port, and an electrical conductivity probe. The main body defines a dosing chamber and comprises at least one dosing port in fluid communication with the dosing chamber. The at least one dosing port is configured to facilitate introduction of dosing fluid to the dosing chamber. The inlet port is coupled with the main body and is in fluid communication with the dosing chamber. The outlet port is coupled with the main body and is in fluid communication with the dosing chamber. The electrical conductivity probe is coupled with the main body and extends into the dosing chamber downstream of the at least one dosing port. The electrical conductivity probe is configured to detect an electrical conductivity of a hydroponic fluid contained in the dosing chamber. A hydroponic system and methods are also provided.

Soil moisture monitoring systems and methods for measuring mutual inductance of area of influence using radio frequency stimulus are disclosed herein. An example device includes a master element stacked vertically on top of one or more slave elements. The master element and slave elements can communicate through a 1-wire bus configuration. The master element can determine the presence and location of each of the one or more slave elements using an auto-discovery process. The master element can issue commands to the one or more slave elements to obtain moisture readings and/or temperature readings.

An irrigation system includes a network hub and a plurality of remote terminal units configured for wireless communication with the network hub. The remote terminal units are connected to a device for irrigation control or sensing, such as a valve for a sprinkler. The network hub is configured to transmit a wireless broadcast to the remote terminal units, in which the wireless broadcast includes a plurality of individual packets transmitted in succession, each of the plurality of individual packets including a network identifier associated with the network hub, a time remaining in a broadcast period of time, and an assignment map indicative of an assigned state for each of the plurality of remote terminal units.

According to one embodiment, a method to increase drought tolerance for grass is disclosed. The method includes estimating by a server a root depth of grass watered by an irrigation system based on one or more of historical watering data of the grass, grass type characteristics, or soil characteristics of soil in which the grass is growing; determining by the server a target water depletion threshold of the grass based on the root depth; generating by the server an irrigation schedule based on the target water depletion threshold and weather information; and transmitting by the server the irrigation schedule to an irrigation controller to selectively activate the irrigation system based on the irrigation schedule.
