A special new absorbent material could soon be making its way to arid regions to help farmers grow crops.
Known as "Solid Rain", the remarkable material is capable of absorbing large amounts of water and then releasing it slowly over a long period of time. Based on materials normally found in ultra-absorbent diapers, just 10 grams of the product can absorb as much as a litre of water. Developed by Sergio Jesus Rico Velasco, the material could make it possible to grow bumper crops in otherwise nonviable arid regions.
"It works by encapsulating the water, and our product lasts 8 to 10 years in the ground, depending on the water quality - if you use pure water, it lasts longer," said the company's vice president Edwin Gonzalez.
"There has been a great deal of excitement and some dramatic headlines in recent weeks about a product that is said to have the potential to overcome the global challenge of growing crops in arid conditions."
