Voronezh doctors offer instead of watering the soil to make a special sorbent. It is a small granules per kilogram which can absorb in about 500 liters of water, while the granules themselves increases approximately 100 times. The action of the sorbent based on the properties of water. Water enters the polymer matrix forming a connection with its walls, and acquires the ice structure that allows it to be secured in the sorbent. That is why the polymer is called “hard water.” When the moisture around the granules is lowered due to bursting matrix, the structure of the liquid, due to which it enters the soil.
“In order to start irrigation, you need to” sow “sorbent field, then sprinkle generously with water. Thereafter, the polymer starts to work automatically maintaining the desired level of moisture for the plant. When this level falls below a certain threshold, the pellets will release water into the soil. And when the rain again swell, absorbing it. One polymer filling with water may be enough for the entire growing season. At the same time, a plus is that the beads are not washed from the soil, so their validity can range from five to ten years. Depending on the type of plants in the soil paid different amounts of sorbent and thus different amounts of water, “- said Head of the Department of Analytical Chemistry MAD Vladimir Selemenev.
Voronezh has to develop its Western counterparts, but almost half the price of – cost $ 10 to $ 12 per kilogram. Furthermore, the sorbent developed at VSU can absorb and give not only the water but trace elements. Also important economic effect: the amount of water during watering, provided the use of the drug, reduced by more than 50%, and water-soluble fertilizers, plant protection products, absorbed by the polymer is not washed out of the soil.
According to the developers, the new technology can find extensive use in the south of the Voronezh region, Volgograd and Astrakhan regions and in Crimea, Dzhankoy region over which a patron Voronezh region.
