Scientists of the Voronezh state University suggested that instead of watering to bring the soil special pellets of its own design. They synthesized sorbent during the rains absorbs water, and in their absence gives moisture to the plants, reported in the VSU.

For the first time this method was proposed by Mexican scientist Sergio Velasco, but the pellets are too expensive. Development of the Voronezh chemists are much cheaper than foreign analogues and has a number of unique properties. Along with the water it absorbs and releases nutrients, is not decomposed during the winter and allows you to halve the costs to irrigate fields.

- To start irrigation, you must "seed" the sorbent, then abundantly watered it with water. After this, the polymer starts to work in automatic mode, maintaining the necessary plants for the humidity level. When this level falls below a certain threshold, the particles will give the water in the soil. And when it rains again swell, absorbing her. One filling of the polymer with water can suffice for the entire growing season. In this case, the advantage is that the granules are not washed out from the soil, so the expiration dates can be from five to ten years, - has told the head of the Department of analytical chemistry, Voronezh state University Professor Vladimir Selemenev.

Kilogram of sorbent is able to absorb 500 liters of water, the granules increase in 100 times. Their action is based on the properties of water: once in the matrix polymer, it forms its walls and becomes the texture of ice, allowing it to gain a foothold in the sorbent. When the level of humidity around the granule is reduced, communication with the matrix break the structure of the liquid changes and it enters the soil.

In addition to scientists in the Department of analytical chemistry, over a sorbent of the specialists on General and inorganic chemistry, with the head of the Department Professor Victor Semenov.

"Hard water" - so called developers pellets - environmentally friendly, eliminates waterlogging and salinization of soils and can become an indispensable tool for farmers in arid regions: the South of the Voronezh region, for example, Volgograd and Astrakhan regions, as well as Dzhankoy district of the Crimea which patron of the Voronezh region, said the University.
