Abstract: An irrigation dripper, comprises an external elongated hollow structure having one or more rigid wall and one or more flexible walls, an internal elongated structure introduced into the external structure to form a pathway for flow between the internal structure and the walls, an inlet for providing water to the pathway, and an outlet on the external structure for allowing water to drip out of the pathway.

Abstract: A method of irrigation comprises supplying water to an inclined irrigation pipe provided with a plurality of drippers such that a pressure at a highest level of the inclined irrigation pipe is at most 200 cm H2O.

Abstract: A system for fabricating an irrigation dripper, comprises several processing stations. One or more longitudinal drilling stations drill in an elongated extruded body of an irrigation dripper a first bore and a second bore, wherein the second bore is contiguous to the first bore and is smaller in diameter than the first bore. An additional drilling station drills an additional bore in the body to connect the first bore with an external surface of the elongated body. An assembling station inserts an extruded rod through the first and the second bores, such that the second bore holds a distal end of the rod to maintain a gap between the rod and an inner wall of the first bore.

Abstract: A system for sensing water status in soil includes a porous material selected for actively proliferating root growth and a water status sensor that is hydraulically coupled to the porous material. The porous material is configured to have an area of at least 0.025 m2.

Abstract: A plant growing container includes a housing comprising side walls defining a cavity and configured for receiving a plant. The housing contains at least two layers of hydrogel separated by at least one layer of spacing material. The container additionally includes an elongated element that penetrates across the at least two layers of hydrogel and across the at least one layer of spacing material. The elongated element is configured as an air channel that transports air from outside the cavity inwards.

Abstract: A method of irrigation is disclosed. The method comprises supplying water to an inclined irrigation pipe provided with a plurality of drippers. The water is supplied such that a pressure at a highest level of the inclined irrigation pipe is at most 90 cm H2O.
