Abstract: A method for improving the sensitivity of an assay to determine the pathogenicity of a plant root pathogen using a soil amendment is presented. The method involves growing the plant root in the presence of a soil amendment after exposure of the plant root to the pathogen. A method of breeding plants is also provided.

Abstract: One embodiment provides a modular green roof tray, house plant growth media and horticulture growth media, and a tree protection mat for weed and moisture control made from recycled disposable diapers. The growth medium and tree protection mat contain superabsorbent materials from diaper that can absorb waters and greatly reduce irrigation so to provide a drought resistant feature. One embodiment also provides a manufacturing process to perform 100% recycling of disposed diapers.
Abstract: A landscaping ground cover system and method is disclosed having a ground mat. The ground mat has one or more fill boundaries defining a plurality of fill areas. At least one of the plurality of fill areas has a fill label corresponding to a pre-defined ground cover fill material to be filled into the corresponding fill area. The fill boundaries may form a graphic design on the mat.

Abstract: A weed control root barrier includes a polymeric sheet material having spaced apart nodules or disks comprising a polymer containing a herbicide. The sheet is porous to permit free passage of water. It may be a non-woven fabric of non-biodegradable polyolefin material. Diffusion of the herbicide directly into the soil is controlled by a barrier material coated on selected portions of the nodules or disks. In one embodiment, essentially all the herbicide in the nodules or disks is directed into the soil via long term migration through and away from the sheet. The barrier layer is coated on portions of the nodules or disks facing the back surface of the carrier to block release of the herbicide to areas of the soil where it is not needed. Exposed surface portions of the nodules can be coated with the barrier material, leaving uncoated sides of the nodules from which herbicide may be released into the soil along a narrow zone of protection generally parallel to the front face of the carrier.
Abstract: A device for protecting a plant includes a body having an open top and an open bottom. The body may be tapered. The body can be pushed into tilled soil around a plant by a person pressing down on the upper edge of the body. The device is used to protect a plant from damage from nearby hoeing, tilling, mowing or other tool use. The device prevents an animal from digging directly next to the roots of a plant. The device localizes water and fertilizer usage to the soil immediately around plant 4.
Abstract: A method and device for containing or encompassing the roots of the plant comprises a base sheet of material containing at least one selected area on the sheet facing the roots, the at least one selected area containing selected nutrients for promoting plant and/or root growth.

Abstract: A root growth barrier and method for use with transplantable plants is provided. The barrier is a bilayer, comprising an inner layer of a root-tip-trapping material bonded to an outer layer of a root-impenetrable material. The inner layer faces the roots of a plant and serves to trap root tips to promote root branching. When a black or dark-colored inner layer is bonded to a white or light colored reflective outer layer, soil temperatures are lower and water retention is promoted. Such a barrier may be used as a freestanding container for plants or be manufactured into preformed rolls for use in plant pots and containers.
Abstract: Embodiments provide methods and apparatuses for supporting various stages of plant growth through layered soils. In embodiments, a soil adapted for supporting a first plant growth phase (e.g. germination) may be proximal, adjacent, or partially surrounded by a second soil adapted for supporting a subsequent growth phase (e.g. a vegetative phase) such that the roots of the plant encounter the second soil as the plant progresses from the first growth phase to the second growth phase. Some embodiments may provide one or more additional soil layers positioned proximal to the second soil, with the additional soil layers adapted to support additional subsequent plant growth phases. Apparatuses suitable for practicing embodiments of such methods are further provided.
Abstract: An apparatus bounds and retains the medium in which a transplantable plant is grown, and promotes the production of lateral root tips by such a plant at all levels in the growth medium. The apparatus includes a sheet having a plurality of hollow protuberances formed with proximal protuberance openings that communicate with distal protuberance openings. The protuberances provide pathways that mimic the natural tendency of the plant roots, so as to decrease the likelihood of the root tips evading the protuberances and promote root-tip growth towards the distal protuberance openings whereby air-root pruning is assured.
Abstract: A walkway adjacent trees is made up of modular sections of perforated plates supported on hinged frames that are supported on spaced piers. Retaining edges of biodegradable material serve to maintain a shallow trench beneath the perforated plates into which leaves or mulch are periodically added. This provides a root-friendly zone under the walkway for tree roots that are watered through the perforated plates and may grow without damaging the walkway. A fringe of plantings maintains the trench level when the biodegradable material disintegrates.
Abstract: A method of shaping a portion of a woody plant into a desired form is provided. The method is effected by providing a root of a woody plant, shaping the root into the desired form and culturing the root under conditions suitable for secondary thickening of the root.
Abstract: A root ball is sculpted from a plant's root system and its surrounding soil using high pressure water ejected from a handheld wand to severe roots of the root system. Mud being formed is simultaneously vacuumed with another handheld wand to form a void between the root ball and the soil surrounding the root ball. The root ball can be wrapped or box for transportation of the plant to another location at which the plant will be transplanted. Positive and negative pressure sources, respectively for the high pressure water and the vacuuming can be mounted on a land vehicle for transportation to plants that are to be prepared for transplantation.
