Fertilization grate and trough system
Disclosed is a fertilization system that finds particular use within a paved surface. The invention allows the root structure of a plant or tree to be hydrated and fertilized by way of an expansible and configurable trough and grate assembly. The trough includes a number of different components that fit together with a tongue and groove interconnection. The trough includes drainage apertures that allow water to run through the grate and into an associated fertilization pit.
1. A plant and root fertilization system for use within a paved surface comprising:
a fertilization pit for containing the roots of the plant, the pit being filled with soil and being bounded by a rectangular trench;
a multipart trough positioned within the trench, the trough including a number of linear sections, corner pieces and linear joints, each of which includes upper opposing L-shaped edges that form a seat, a U-shaped body intermediate the L-shaped edges, and a series of drainage apertures formed within the u-shaped body, the corner pieces and linear joints further including opposed tabs formed within the u-shaped body, the u-shaped body of the linear sections being inserted into the tabs of the corner pieces; and
a series of grate covers, each of the covers including a top textured surface and being positioned within the seat of an associated linear section, corner piece or linear joint of the multi-part trough;
a particulate fertilization material positioned within the multipart trough such that when water enters the trough through the grate cover, the material is washed out of the trough through the drainage apertures and into the fertilization pit.
2. A plant and root fertilization system comprising:
a fertilization pit for containing the roots of the plant, the pit being filled with a particulate fertilization material and being bounded by a trench;
a trough assembly including a number of linear sections and corner pieces that are assembled into a closed configuration via a tongue in groove interconnection, the linear sections and corner pieces each including a series of drainage apertures, the trough assembly being positioned within the trench such that the drainage apertures are in fluid communication with the fertilization pit;
a series of grate covers removably positioned over the linear sections and corner pieces to thereby cover the entire trough assembly;
a particulate fertilization material positioned within the trough such that when water enters the trough assembly through the grate covers, the material is washed out through the drainage apertures and into the fertilization pit.
3. The plant and root fertilization system as described in claim 2 wherein the trough assembly includes liner joints in addition to the linear sections and corner pieces and wherein the linear joints, linear sections and corners pieces all include U-shaped bodies.
4. The plant and root fertilization system as described in claim 2 further comprising a tab that is formed within each of the corner pieces and wherein the linear sections include a u-shaped body and wherein the tongue in groove connection comprises inserting the tab over and adjoining u-shaped body.
5. The plant and root fertilization system as described in claim 2 wherein the grate covers include a top textured surface.
