Trees Buried Diffuser


Presentation

Trees Buried Diffuser

The Buried Diffuser (15x15cm or 15x30 cm) can be used for the irrigation of all kind of trees such as banana, mango, papaya, litchi, guava, avocado, pomegranate, date palm, oil palm, apple, apricot, grape, olive, orange, citrus, almond, nut, pear, fig, etc.

Buried Diffusers are installed in holes, 50 to 70 cm below the topographic soil surface. It is possible to install the diffusers in the plantation before the installation of the tree. In this case the diffuser should be 50 to 70 cm far from the axis of the tree. When the diffusers are added after the trees plantation, they should be installed in the extremities of the canopies.

For the irrigation of shrubs and perennial, medicinal or ornamental herbs, the diffusers are installed in holes 20 to 40 cm deep below the topographic soil surface and 20 cm far from the axis of the plant.

The Buried Diffuser can be used for all kind of trees such as banana, mango, papaya, litchi, guava, avocado, ficus indica, pomegranate, date palm, oil palm, apple, apricot, grape, olive, orange, citrus, almond, nut, pear, fig, etc.

The use of Buried Diffusers for trees has several advantages such us huge water saving, energy saving, soil labor reduction, weeds reduction, diseases reduction, irrigation frequency reduction...

Putting-In

    For the installation of diffusers for trees and shrubs, holes are dug at the edge of the canopy of the tree or shrub.

If the canopy is between 1m and 2m, it is recommended to put 2 diffusers. If the canopy is between 2m and 4m, it is recommended to put three diffusers. Beyond 5m it is recommended to put 4-6 diffusers. Each square hole (40x50 cm) or circular hole (ϕ 35-40 cm), must have a depth of 60 cm.

We put the diffuser at the bottom of the hole, then we bury the diffuser while compacting well the fill. If we want to completely bury the ϕ 3/6mm pipe, the dosing emitter, the water distribution pipe (ϕ 16 or 20mm) and the ϕ 16mm diffuser’s pipe, we should decreases by 10 cm the length of the diffuser’s pipe.

For the water distribution pipe (ϕ 16mm or 20mm), particularly for canopies more than 5m, there may be two configurations:

A first configuration where the pipe is at the soil surface or buried at 10 cm. This concerns as well as the part of the pipe between the trees and the part with the dosing emitter along the edge of each canopy.

In the second configuration the water distribution pipe (ϕ 16 or 20 mm), is composed of a fixed buried part (at 10 cm depth) or not, with dosing emitters and another part removable after irrigation. Each removable portion is connectable to the fixed parts of two adjacent trees of the same row. This connection is made by two junctions or bends 16 or 20 mm. When removing the removable part for storing, we should close the openings of the two ends of the fixed part to avoid the entry of sand into the pipe. This configuration is only valid when we have a deep soil (minimum 1 m under the diffuser), allowing to store enough water for the tree for 2 to 3 months. Thus, the irrigation is realized just 4 or 6 times per year. Each irrigation must be continuous (day and night) and can last one to two weeks. 

TIPS: If the soil is hard and difficult to dig through a motorized auger or manually, we can set up water dosing emitters connected to the water distribution pipe (ϕ 16 or 20 mm) along the edge of the canopy. We let these dosing emitters discharge water for 10 to 12 hours to moisten the soil where the holes would be dug. This "pre-irrigation" greatly facilitates digging the hole for the diffuser.
