Hi Govind, Thanks for the comment. About irrigation water storage in the soil layers below 0.5 meter should be equal to the need of the tree not only to keep it alive but to produce the maximum yield. In the case of Anticipated irrigation we give only the needs of 1 year during 1 till 3 weeks(non stop day and night) the soil below 0.5 meter should be at least 0.7 meter thick. . In the case of water injection the soil below 0.5 meter should be at least 1.5 meter to inject the needs of 2 years and 2 meters to inject the needs of 3 years. to store the needs of 1, 2 or 3 years in the deep soil layers, theese layers sholud contain more than 10% clay. Anticipated irrigation and water injection in the deep soil layers, using buried diffusers, both concepts are used by tunisian farmers, since 2013. To see that you can visit us and we will show to you the fields where both concepts are applied. we are discussing with an indian company to introduce the buried diffuser in India. If the discussions are positive, we will manage pilot farms with anticipated irrigation and with water injection in the deep soil layers. Recontact me again nex November to inform you about the negotiations with the indian company. My email is bchahbani@chahtech.com

Thank u chahbani for ihe prompt and positive reply. I a very much impressed with the concept and the approach: THE NEED OF THE DAY. The video indicated the demonstration on deep soil sustaining the fruiting citrus trees. U have narrated the requirements nicely. In view of the climate change, increase in population, per head water needs and limitations on water availability, we will have to think beyond drip irrigation to lower down the energy and water needs of agroecosystems, with increased production and improved quality. I am very happy to know that u are planning to be in India in near future.
