A mobile drip irrigation system includes a plurality of drip tubes anchored at a first end to a water supply conduit. As the mobile irrigation system travels across a surface to be watered a second, free end of each drip tube is pulled along the surface to provide precise and uniform water distribution through the drip tubes. A cable extending across each section of the mobile irrigation system is attached to the plurality of drip tubes within that section, with the cable movable via a winch mechanism to shift the position of the drip tubes within that section to correspondingly shift the drag path of the tubes to a desired location. In exemplary embodiments, a lower manifold distributes water to the drip tubes, and in further embodiments a support restraint provides support to the lower manifold.

The invention includes systems and methods for applying liquids to the ground including an applicator with at least one conduit with at least one delivery outlet, and a support structure for the conduit where the conduit provides a fluid path to the delivery outlet from a liquid reservoir on a toolbar or agricultural machine. The systems and methods provide consistent placement of the liquids close to the stem of row crops, preferably within about 5 inches of the base of the stems. The systems and methods also provide this consistent placement over a variety of distances or lengths of the rows, including up to a mile in length. The systems and methods also allow for a variety of speeds for the application of liquids in this consistent manner.

An emitter coupler is provided, such as for use in an irrigation dripline. The emitter coupler includes a body with two portions for coupling to two supply tubes. The emitter coupler also includes a conduit defined by the body that receives fluid from a supply tube. The emitter coupler also has an emitter including: an emitter inlet that receives fluid from the conduit; an emitter outlet downstream of the emitter inlet with the inlet receiving fluid at a certain pressure and the outlet emitting fluid at a reduced pressure; and a pressure reducing flow channel disposed in the emitter between the inlet and the outlet. The emitter coupler further includes a housing that encloses the emitter. The housing is in fluid communication with the conduit and defines an outlet of the emitter coupler. A dripline with at least one emitter coupler is also provided.

An irrigation system for an area receives wide-area meteorological prediction data and sensors deployed within the area collect local-area sensor data. A processor stores received data as historical wide-area meteorological prediction data and data from the sensors as historical local-area sensor data. The processor determines a relationship between the historical wide-area meteorological prediction data and the historical local-area sensor data based on the historical wide-area meteorological prediction data and the historical local-area sensor data, and calculates a prediction on a local-area parameter for a future point in time based on current wide-area meteorological prediction data, and the calculated relationship. The area is then controlled based on the prediction.

An irrigation device has a generally arc-shaped housing defining an opening through which a plant can grow when the device is placed on a ground face during use. The device further includes a plurality of stakes that can be fitted to the housing, wherein each stake can be rotated between a deployed state where the stake projects away from the housing in a position suitable for being placed into the ground and a non-deployed state where the stake is oriented sideways projecting into the opening.

The problem of the present invention is to provide a biodegradable resin composition that can be easily molded in a short time, with molded bodies therefrom having appropriate flexibility. The resin composition for solving the above problem comprises 100 parts by mass of poly(butylene adipate/terephthalate) and 1-10 parts by mass of an aliphatic polyester having a certain structure. The amount of the poly(butylene adipate/terephthalate) is 80% by mass or more based on the total amount.

An irrigation device includes a hollow element having an at least partially closable opening and having a substantially open and optionally closable annular shape, one end of the hollow element having, at the opening, an outward radial extension to form a counter-curve defining a guiding section with a concavity different from the concavity of the remaining annular element. The device further includes a tubular element inserted or insertable in the hollow part of the annular element and provided with a plurality of openings to enable the dripping of a liquid when such liquid is introduced at one end of the tubular element, the opposite end being closed or closable with a plug or connectable to the first end with a connector.
