The aim of the proposed product is to save up to 50% of irrigation water by using a microporous solid made from clay enriched with calcium and magnesium or with any other element that is not environmentally polluting and is non-toxic to living organisms. The microporous solid acts as a water storage reservoir. This method allows: 1 - The use of ordinary clay, to which there are added fusible additions (sawdust or coal dust), calcium hydroxide and magnesium. It is then formed into small 5 mm balls and baked in a furnace at a temperature close to 810 °C. 2- By mixing into soil to a depth of 20 to 25 cm before planting, a well aerated soil is obtained equipped with the water reservoirs. 3- This technique for saving agricultural irrigation water uses totally natural products that have no detrimental effects on plants or humans. 4- This product is very practical for large agricultural plantations (grains, for example) or palm-tree plantations in desert areas. 5- The product is very effective in desert areas. It makes it possible to save more than 50% of irrigation waters. 6- The proposed product is very easy for farmers to use, requires no maintenance and has no negative effect on the environment, plants or humans. |
