After more than fifteen years of research, the POLYAGRI Company designed and developed HYDROSOL: a polymeric substrate, which is hydro-retentive, fertilizer, curative and\or corrective of salinity.The full-scale experiments demonstrated both the effectiveness and efficiency of the HYDROSOL products range on any type of crops, soils and climates. Substrate agricultural crop of new generation, combining the functions of hydro-retentive and nutrient reserves : the process is based on a unique method by encapsulating fertilizers, plant health treatment or correction in polymerics crystals. HYDROSOL is a complete hydro-retentive substrate containing all the elements and substances essential for plant growth. HYDROSOL is able to absorb and to retain more than 300 to 500 times its volume in water. Plant roots penetrate the granules to reach semi-permeable polymeric pockets which contain the captured and absorbed water, all the minerals and all the active substances necessary for plant germination and growth (crop inputs). These reserves of water and essential elements are slowly released by plant root pumping depending on water and nutritive and/or curative needs of plants. The biodegradable and non toxic polymeric compound is in osmosis with the soil and the environment. The key points of HYDROSOL: Irrigation water savings by more than 50%! Thanks to its high hydro-retentive power, Hydrosol can absorb up to 500 times its volume in water and release it back by root pumping depending on plants needs   Use of fertilizers and crop inputs reduction by more than 50% HYDROSOL is both a comprehensive and an economical product. It contains all the nutrients and/or curative substances essential for plant growth.   Protection of the environment against the migration of substances into the soil The roots penetrate the Hydrosol semi permeable pockets to reach the water and crop inputs reserves.These reserves are slowly released by root pumping thereby preventing their migration into the soil.   An economical product which reduces operating costs and expenses The technical installation system of Hydrosol and its price are very attractive.Hydrosol allows making savings in equipment, water, energy and time while increasing crop yields.   Text in arabic
