The 'solid rain' can save a 80 percent of water on crops.

solid rain.

This is a biodegradable polymer in powder nontoxic, capable of absorbing 200 times its weight in water.

The powder becomes a gel upon contact with water, storing and providing moisture to the roots of the plant during 40 days.

The Mexican engineer Sergio Jesus Rico, researcher at the National Polytechnic Institute of Mexico, It has developed an irrigation system called "solid rain", which can save about 80 percent of water on crops.

polymers, the size of a grain of sugar, ionize water molecules and hold them together in one body. Each small grain (Superabsorbent acrylates) It is able to increase up 500 times its original size, and maintain unchanged the properties and characteristics of water.

So that one kilo of these polymers is sufficient to solidify 500 liters of water, can be maintained for ten years in that state.

The use of these polymers can be performed either dry or with water already included.

Dry can be buried in the place of cultivation line, in a ratio of 25 Product kilos per hectare of crop. Thus, Upon irrigation polymers absorb water making it available to the plant roots, thus saving five irrigations and 80 percent by volume water.

As he indicated by the press Rico, the polymer does not dissolve in water, so the elements of your formula does not pollute the land or are absorbed by plants, but it is integrated into the floor as if it were a molehill.

When applied to the soil at a ratio of 200 grams per ton of soil, their presence is negligible.

This system can be used both extensive and intensive agriculture or gardening, according to its creator.
