Abstract: An agricultural trellis system is provided and generally includes a notch configured to receive a trellis wire therein and selectively release the trellis wire upward during mechanical pruning. The notch can be positioned on an above-ground portion of a vertical line post or a cross arm. The notch can include a tab extending upward from the bottom of the notch, and a first edge and a second edge each formed on the body. The first edge can be a flat edge and can be positioned laterally outwardly from at least a portion of the second edge, which can be a curved edge. The notch can include a retention protrusion extending laterally into the notch toward the second edge to a position where a lateral distance between the retention protrusion and the first edge in a direction normal to the central plane is less than a diameter of the trellis wire.

Abstract: An agricultural trellis system is provided and generally includes an anchor stake configured to extend at least partially into the ground, a mounting plate coupled to the anchor stake, and at least one trellis arm pivotably coupled to the mounting plate. The mounting plate can have a pivot aperture, a first plate aperture, and a second plate aperture configured to position the trellis arm at different angles relative to a plane orthogonal to a major axis of the anchor stake. The trellis arm is pivotable between alignment with the first plate aperture and disposed at a first angle, and alignment with the second plate aperture and disposed at a second angle different than the first angle. A pin can couple the trellis arm to the mounting plate via the first or second plate apertures. In use, the system can have two trellis arms disposed at the same or different angles.

Abstract: A biodegradable spectrally selective grow tube or tree shelter that improves the establishment of woody plant forms by reduction and/or elimination of certain biotic and abiotic stress factors. The grow tube may provide an enhanced micro climate that is humid, CO2-replenished and promotes photosynthesis by selectively propagating photosynthetically active radiation. In addition to providing a physical barrier to wind and herbivores, certain embodiments of the grow tube can also provide protection from chemical sprays while permitting ventilation of the grow tube. Various embodiments of the spectrally selective grow tube may comprise separate interior and exterior members for enhancement of the interior and exterior surface functions and that may be constructed from a biodegradeable polymer or paper-based material. The interior member can be dyed or pigmented to selectively transmit wavelengths of the visible spectrum known to promote photosynthesis, such as red light and/or blue light.

Abstract: A spectrally selective grow tube or tree shelter that improves the establishment of woody plant forms by reduction and/or elimination of certain biotic and abiotic stress factors. The grow tube may provide an enhanced micro climate that is humid and rich in CO2 and promotes photosynthesis by selectively propagating photosynthetically active radiation. In addition to providing a physical barrier to wind and herbivores, certain embodiments of the grow tube can also provide protection from chemical sprays while permitting ventilation of the grow tube. Various embodiments of the spectrally selective grow tube may comprise separate interior and exterior members for enhancement of the interior and exterior surface functions and that may be co-extruded. The interior member may be dyed or pigmented to selectively transmit wavelengths of the visible spectrum known to promote photosynthesis, such as red light and/or blue light.

Abstract: A method of manufacturing a raschel knit net having square meshes is provided. The method consists of providing a raschel knit net having diamond meshes, and cutting diagonally across the net from selvedge to selvedge. Multiple pieces of cut net are rotated and aligned, selvedge to selvedge, such that the meshes are square shaped with the mesh strands running generally lengthwise and widthwise. The aligned selvedges are then joined together, creating a net having square meshes, such that the dimensions of the net are fixed lengthwise and widthwise. The joined selvedges create a dimensional control portion extending diagonally between lengthwise edges of the net.
