A clog resistant in-line irrigation emitter or nozzle assembly having an emitter structure designed to be inserted into an extruded tube as part of a drip irrigation system. The nozzle assemblies take the high pressure and flow inside the tube and produce a desired flowrate (selectable depending on the requirements of the environment). The emitter of the present disclosure has a higher efficiency than traditional pivot or sprinkler systems or known emitter devices. The emitters not only provide the appropriate pressure attenuation; they resist clogging from the grit and debris in available ground water. The clog resistant in-line irrigation emitter gives a greater pressure attenuation for its physical dimensions than comparable devices and provides an optimal design of a pressure compensating device that improves diaphragm performance. The instant disclosure does allow for the pressure compensation device to be used with various embodiments of a pressure reducing components.

A plant irrigation device includes a support that surrounds a plant and provides an opening through which the plant extends. A drip tube is attached to the support and connectable to a water source. The drip tube has a series of spaced apart apertures or water emitters along a length thereof permitting water to exit the drip tube and into the ground surrounding the plant.

A heat delivery system for agricultural applications, the system including: piping including alternate heat insulated segments and heat transferring segments, the piping being configured with a fluid flow path extending through the alternating heat insulated segments and heat transferring segments; and a fluid propelling arrangement configured for motivating flow of heat accommodating fluid within the fluid flow path.

A pressure compensation member, an irrigation drip emitter, drip lines and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The pressure compensation member being suitable for use in conventional emitters or alternate emitters being provided having either a uniform elastomeric emitter body configuration or a poly-material emitter body utilizing an elastomeric pressure compensation member. Various methods are also disclosed herein relating to the pressure compensation member, emitters and/or drip line using such pressure compensating members and/or emitters.

An irrigation modeling framework in precision agriculture utilizes a combination of weather data, crop data, and other agricultural inputs to create customized agronomic models for diagnosing and predicting a moisture state in a field, and a corresponding need for, and timing of, irrigation activities. Specific combinations of various agricultural inputs can be applied, together with weather information to identify or adjust water-related characteristics of crops and soils, to model optimal irrigation activities and provide advisories, recommendations, and scheduling guidance for targeted application of artificial precipitation to address specific moisture conditions in a soil system of a field.

This emitter comprises: an emitter body having a groove, a recess and a through hole on the upper surface thereof; and a film joined to the upper surface. This drip irrigation tube comprises: a tube; a discharge opening that is a hole extending through a wall of the tube; and an emitter joined to an inner wall surface of the tube at a position of the inner wall surface corresponding to the discharge opening.

A clog resistant in-line vortex emitter and drip irrigation assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex chamber 100 also al lows for a lower exponent than traditional circuits. This gives a pressure regulating property to the no-moving-parts circuit. The vortex emitter allows for some pressure regulation without sacrificing recyclability or requiring moving parts. The vortex circuit of the present disclosure is optimized for an emitter efficiency Ef value wherein Ef=(k/Ackt)*Amin such that k is a unitless head loss coefficient, Ackt is the area of the circuit, and Amin is the minimum cross sectional area of the circuit. A higher k per a given area with larger dimensions allows for a smaller part with a lower chance of clogging.

An implement adjusting system having an implement with a plurality of adjustable components, a plurality of input values, at least one controlled system configured to adjust at least one of the plurality of adjustable components, and a controller that receives the plurality of input values, the controller configured to reposition the plurality of adjustable components based on the plurality of input values. Wherein, the plurality of adjustable components are repositionable by the controller based on the input values.

A wireless system is provided for monitoring environmental, soil, or climate conditions and/or controlling irrigation or climate control systems at an agricultural or landscape site. In some embodiments, the wireless system includes at least one wireless control nodes for monitoring environmental, soil, or climate conditions and/or for controlling one or more irrigation or climate control systems at the site. The wireless system also includes a web based application or a cell phone application and a gateway coupled to a communications network. The communications network is configured to transfer data to and receive remote control commands or queries from an end-user.

An emitter forms a flow path that runs to a discharge part from a water collecting part for receiving an irrigation liquid in a tube. The flow path includes a flow rate control part which includes: an end surface including a concave inclined surface that faces a film for receiving the pressure of the liquid inside the tube; a hole that opens at the center of the flow volume control part and connects to the discharge part; and a groove crossing the inclined surface and running to the hole. When the film adheres to the inclined surface as a result of the pressure of the irrigation liquid inside the tube, the flow volume of the irrigation liquid inside the emitter is controlled so as to be a volume that can pass through the groove.
