Sergio Rico markets his product through his own Silos de Agua company and exports to nine countries, due to the success of the system that is already used by Argentine, Spanish, French, Indian, Israeli and Russian farmers.
Solid rain is a non-toxic biodegradable polymer powder that is capable of absorbing 200 times its weight in water; Upon contact with water, the powder turns into a gel and can store the liquid for up to 40 days.
Farmers use it to store rainwater and use it as an irrigation method: They sprinkle the powder under their crops so that when it rains the chemical turns into a gel and can store the liquid for up to six weeks.
25 kilograms of the product are required for one hectare of cultivation.
"The results are extraordinary because the root remains moist for two months and is rehydrated repeatedly with rainfall," says Rico, according to the Agroalimentando site.
According to the inventor, "solid rain increases the productivity of corn crops five times", where the product has been well tested.
"We have already measured the results in corn crops in Jalisco where with a traditional irrigation system we obtained 500 kilos of corn per hectare and with this we obtained 10 tons per hectare," he said.
In addition, this chemical engineer explained that the system allows farmers to save up to 80% in costs, since they use less water, fertilizers, electrical energy and labor.
Their product is already used in Argentina, Ecuador, the United Arab Emirates, Spain, France, India, Israel, Peru and Russia and is about to enter Haiti.
