Methods for fumigating soil include applying over fumigant-treated soil a multilayer polymeric film to form a vapor barrier between the fumigant-treated soil and the atmosphere to at least partially contain the fumigant. The multilayer film includes at least one barrier layer comprising at least one vinylidene chloride polymer and protecting layers on each side of the barrier layer. The multilayer film preferably has at least one UV protecting layer and optionally at least one reflective layer.

Waterproof and UV (ultraviolet) radiation blocking protective cover (1) for hanging fruit, CHARACTERIZED by a sheet (10) made of an expanded polyethylene material that blocks ultraviolet radiation (EPE-UV), whose shape is a flat geometric figure, with a main straight cut (11) running from the midpoint to the edge of the sheet and an arrangement of cuts and grooves that make up the attachment system when the cover is fitted on the fruit.

A fill tube for a water filled plant protector is formed by folding the top edge of the outer wall of the protector between the inner and outer walls and capturing the edge with the welds that create the vertical columns. The protector is filled through a port in the tube. Air is vented as the columns fill with water through the open top of each column.

Crop protection netting for covering trees or other plants for insect and bird exclusion is of a knitted mesh construction, comprising knit intersections in the netting and connecting yarn portions between the yarn intersections which extend substantially linearly between intersections. The netting is lightweight and stretchable in multiple directions.

Objects of the present invention are to provide a film for an agricultural greenhouse that can maintain a CO.sub.2 concentration necessary for the photosynthesis of plants even when ventilation is not performed and to provide an agricultural greenhouse using the film. The film for an agricultural greenhouse of the present invention is a cellulose film which contains a cellulose acylate resin and has an equilibrium moisture content of 4% to 8% at a temperature of 25° C., a relative humidity of 80% and a thickness of 60 to 200 μm.

A membrane for covering the cut end of a tree trunk to prevent the tree from creating a seal after it has been cut. The membrane is attachable to the cut end surface of the tree trunk and includes a hydrating layer comprising a hydrogel. The hydrogel, made up primarily of water, adheres to the cut end surface of the tree trunk to continue hydrating the tree, and prevents air from reaching the tree's exposed transport tissue. In some embodiments, the membrane includes a backing layer and a release layer on opposite sides of the hydrating layer.

A modular cell that may be used with other cells to form a matrix under a load bearing feature, the cell being a single piece molding that supports a compressive load placed thereon, the molding including a void space defined within: a skirt shaped support member defining a substantially planar surface with an opening therein; and at least one leg integral to and extending from the support member. The cell further includes at least one separate linking member that releasably links together multiple cells to form a matrix of cells. The cells may be linked together vertically and/or horizontally. The cell and matrix include greater load bearing capacity and rigidity through aligned legs to carry the weight as well as interlinking members that act to share the load among the various cells. The design also requires less material hence is cheaper to produce. The void space is also easily accessed hence allowing for easy access, filling and laying of utility lines where needed.
