New concepts: Anticipated irrigation and Water injection and storage in the deep soil Layers of the plantations using the Buried Diffuser
o Concepts
After the use of the buried diffuser for the regular irrigation, Chahtech SA has created a new method for “anticipated irrigation” and “water injection in the deep soil layers”. The goal of this new concept is to save and conserve the huge of water received during the wet season, for the next dry season.
More then that, in other regions of the world the challenge is higher: how to save and conserve the huge of water received during the wet or rainy years to be used during the long dry period: one till 3 years.
Both “anticipated irrigation” and “water injection” are solutions for drought mitigation and for climate change adaptation and for the regularisation of the crops yields.
o More details:
The “anticipated irrigation’’, instead of irrigation during the hot or the dry season, the
irrigation using buried diffusers is done during the autumn and winter or during the rainy season. The amount of water of the “anticipated irrigation” should cover the total need of the crop during the hot or dry season (spring and summer). This water amount is stored in the deep soil layers will be used by the deep or sub surface roots systems of the crops.
The Water injection in the deep soil layers is useful especially for trees crops. The injected
water comes from: dams, rivers, and springs. The amount of the injected water could cover the need of the trees for several years (2 to 3years) when the soil below 50cm is thick (1 meter or more). This injected water is conserved (stored) in the deep soil layers (50 cm below the soil surface) and used later by the deep root systems of the trees during a long drought period: six months till 3years. During the Drought the trees produce normally using the injected and stored water. According to long injection period (15 days to 90 days none stop: days and nights), it is recommended to use our “energy less” system of water “pumping” and distribution using the gravity. This system uses our second product: “the draining floater”. This system is described in another report which could be downloaded from our website: www.chahtech.com
o Trials in Fields
On February 2013 Chahtech SA started 2 trials in the field of a farmer in Nouvelle Matmata Arid region (South of Tunisia).
The first trial includes the installation of diffusers (each tree has 3 diffusers model 15/15) for 2 olive trees suffering from long drought (75% of the leaves are dried). Each tree was irrigated with 2250 litters using the diffusers. 2 Months later (April 2013) the 2 irrigated trees become green with new leaves and young branches. The irrigations water given to each tree is sufficient for 4 months.
The second trial is the injection of 10 cubic meters of water in the deep soil layers (below the buried diffuser) using only one buried diffuser model 15/30. The irrigation duration is 52 continuous days; no stop (24/24 hours, 7/7 days).
The excavation of a trench (6 meters long and 4 meters deep) to discover the wetted area of the deep soil layers below the buried diffuser which injected 10 000 litters showed the wetted area result of the injection of 10000 litters has 6 meters diameter and 2 meters deep. This means, that a trees equipped with 4 buried diffusers, will r receive, after 52 days of injection, 40 cubic meters. This volume (40 cubic meters stored in 100cm soil below the diffuser , containing minimum 10% clay), is sufficient to maintain the tree in life and in optimal production conditions, during 4 completely dry years.
