A fertilizing device has at least one of the tubular body, and the tubular body is inserted in the soil in which the plant is planted. The tubular body has a containment space inside and a plurality of through holes on its surface. The tubular body is provided with at least first separated section at its top, and a number of second separated sections among the through holes. When the tubular body is inserted into the soil around the plant, the first separated section of the tubular body is exposed, and the second separated sections are configured for adjusting the spacing between the through holes. When the fertilizer and moisture are introduced into the containment space through the top of the tubular body, the fertilizer and moisture are discharged through the through holes of the tubular body, so that the fertilizer and water can penetrate into the deeper soil more evenly and the plant roots and soil can absorb nutrients and water more completely.

The invention relates to a device for conducting water in a ground surface, comprising a nonwoven layer introduced into the ground (6), which nonwoven layer has at least one conduit strand (4) provided with passage openings (5) for conducting water. In order to create advantageous construction conditions, it is proposed that the nonwoven layer forms a grid (1) made of intersecting arrays of grid strands and comprises a nonwoven web (3) extending along the conduit strand (4), and that at least one array of grid strands formed of nonwoven strips (2) adjoins the nonwoven web (3).

An apparatus for installing multiple strands of hose below a surface of terrain is provided. The apparatus comprises a chassis and rotating trenching blade assemblies connected to the chassis. The trenching blade assemblies are configured to dig parallel trenches when the apparatus is pulled along the terrain. Curved hose guides are connected to the chassis in trailing positions behind the trenching blades. Each hose guide receives hose from a hose reel on reel mounts connected to the chassis and deposits the hose into a trench dug by a trenching blade assembly. Trench fillers connected to the chassis trail the hose guides. Each trench filler is aligned with a respective hose guide and comprises a number of blades configured to push soil excavated from a trench back into the trench when the apparatus is pulled along the terrain.

This invention is related to a gravity flow, multipurpose bidirectional nonpressurized climate smart subirrigation conduit apparatus for managing soil moisture and growing plants. The subirrigation conduit apparatus creates a suspended virtual water table at the desired buried depth, thus creating an anaerobic saturated zone and a capillary fringe. The capillary fringe is described in the art as a moisture zone that has perfect air and moisture mixture for plant growth, can also be used to irrigate with high turbidity obstruction liquids such as precipitation runoff and alternative waters such as untreated greywater. When too much water is present within the landscape, the Multipurpose bidirectional nonpressurized climate smart subirrigation conduit apparatus can be used in reverse flow to drain the landscape. Bidirectional nonpressurized flow is achieved by gravity water equalization thus cutting any need for energy consumption.
