The present invention provides structures that maximize the use of minimal ground space or pot soil by providing generally vertical outward-sloping multiple cords or net trellis such as to offer increasing volume for plant foliage with height, which is adjustable to the user's desire. A compact kit includes at least two elongated leg member, and at least one elongated support, and can be assembled into structures up to approximately twice as wide at the top as at the base where the plants begin growing in soil. Flaccid replaceable cords when installed incline generally outward and upward to top horizontal rods supporting wining plants to grow generally vertically and even horizontally across the top.

A system and method of abating air pollution and stimulating crop growth. A reagent is introduced to a crop canopy to neutralize air pollutants within said canopy, wherein the reagent induces an oxidation-reduction chemical reaction with the air pollution present throughout the acreage of crops, and by means of the reaction effectually neutralizes the harmful effects of the air pollutants on the crops. The reagent is diluted using a venturi valve or other means. The flow rate of said reagent is regulated using an electronic control unit, based on data collected from at least one type of sensor in the canopy that is in communication with the control unit.

Technologies are described for systems and devices to provide photosynthetically active photons to a plant. The systems may comprise an above canopy light source. The above canopy light source may be an electromagnetic radiation device. The above canopy light source may be located above a canopy of the plant. The above canopy light source may emit photosynthetically active photons of a first intensity downward, towards a canopy of the plant. The systems may comprise an under canopy light source. The under canopy light source may be an electromagnetic radiation device. The under canopy light source may be located below the lowest branches and leaves of the plant. The under canopy light source may emit photosynthetically active photons of a second intensity upwards, away from a root system of the plant. The second intensity may be 0-50 percent of the first intensity.

The present disclosure concerns different embodiments of field protection systems to form a protection over a field to be protected, comprising a flexible membrane assembly comprising a flexible membrane and a plurality of flexible membrane-deploying clips mounted thereto or a plurality of foldable frame members at least partially engageable with a field-facing surface of the flexible membrane, the foldable frame members comprising first and second opposed ground-securing end portions. It also concerns corresponding methods for forming a protection over a field.

A netting installation, for use in tree fruit production, which comprises a framework comprising a plurality of uprights which are mutually spaced to form an array of the uprights. Each upright is installed into the ground using a helical ground anchor, and has a combination of upper and lower slidable parts to removably fit an upper part onto a lower part which is installed in the ground. Cables are attached to the upper ends of the uprights to form a cable network at least 3 meters above the ground. A plurality of nets are mounted on the cable network to form an array of nets. A releasable net tethering system connects the nets to the cables using connectors fitted between the peripheral edge of a respective net and a cable, wherein each connector has a preset maximum threshold of tensile strength.

A light shielding net, which can improve productivity by facilitating a weaving process, can be wound by a winding device due to a high winding strength, and can express various colors, thereby adjusting a light shielding amount and improving a design aesthetic sense. To this end, a warp yarn is made of a PE monofilament, the weft yarn is made of a PE film, and the two warp yarns are repeatedly woven in a Leno weave form surrounding each weft yarn.

A plant for the production of electrical energy comprising a support structure formed by support poles (2) aligned along a first axis (X) fixed to the ground; said structure being configured with a plurality of parallel rows (Fi) of such poles (2) with any orientation, causing the formation of a two-dimensional structure along such axis (X) and a second axis (Y) substantially orthogonal to the first to form a chessboard structure, this structure being installed on agricultural land (T), and the distance between the support posts, along both the X and Y axes, is such as to allow the passage and processing of the land by agricultural vehicles or vehicles, on said support structure and in particular on rows of poles being positioned devices for the generation of electricity, characterized by the fact that the plant includes means for the power supply of such electric agricultural vehicles or vehicles that work the land (T) where the plant is installed that use part of the electricity produced by the plant itself.

A retractable roof structure has a pair of longitudinally spaced supports, guide wires extending between said supports and positioned to support a covering in a required profile. The covering comprises a plurality of sections arranged in seriatim along the guide wires with each section slidably supported on the guide wires so as to be moveable between an open position in which the area beneath the covering is exposed and a closed position in which the area beneath the covering is covered. A drive member extends between the supports and is connected to one end of each of the sections at a first location to move the one end along the guide wires. A tensile member, such as a rope or cable, extends from the peak of the leading edge of one section to the lower corner of the leading edge of a section along a path so that movement of the peak is transmitted by the tensile member to the eaves to move the section along the eave guide wire in the same direction.

An agricultural yield apparatus with a container made of a material that is impermeable to water and inert without leaching impurities to the surrounding natural environment and thereby is effective in segregating contents of the container from the surrounding natural environment and blocking seepage of the contents to the surrounding natural environment. The container encloses nutrients, water and a growth medium such as soil. The top of the container is closed except for at least one water and nutrition port and at least one vegetation growth port (or neck). The trunk of the vegetation passes through the at least one vegetation growth port (or neck). The container may be closed by a root membrane overlay having holes. The trunk of the vegetation passes through the holes in the holed root membrane overlay. Root direction channels may be beneath the overlay.

A solar farm includes a plurality of I-beams having a first attached end and a free end. A plurality of solar panels are mounted to the free ends of the plurality of I-beams. The solar farm also includes a plurality of vegetation management shields attached to the plurality of I-beams. The vegetation management shields are positioned at or near the ground and prevent vegetative growth near the plurality of I-beams. At least one vegetation management shield includes a disk having a first side, and a second side. The disk of the at least one vegetation management shield has an I-beam-shaped opening therein. The opening passes through the disk. The disk also includes a rib structure positioned between the first side of the disk and the second side of the disk. The disk can also be formed as a first portion and a second portion that fits around an I-beam.
