The deserts cover about a third of the earth's surface, exactly 30% of the land emerged: if for centuries man has avoided these places hostile to human presence, now, taking into account the worldwide demographic increase and the decrease of the arable land, he looks at them as probable agricultural land. Madness? There are several techniques that promise to make sandy soil useful: that of the Norwegian scientist Kristian Morten Olesen seems to be the most promising.
The mix of clay and water was called Liquid Nanoclay (LNC) and in 2015 won the first prize of the contest ClimateLaunchpad, an event in which the most innovative technologies are presented in favor of the environment.
The mixing of clay and water is carried out without any chemical additives: the mixture is then sprayed directly onto the dry sandy soil, thus reducing the dispersion of ground water by 65%. The treatment has a maximum duration of 5 years.
The effect of Liquid Nanoclay is to saturate the first 40-60 cm of soil, in order to make it permeable like a sponge and able to retain moisture and nutrients.
On the land treated with Nanoclay it was possible to grow the most various plants and vegetables, thus opening up again the hope of being able to use the vast deserts that characterize our planet, all in a natural way.
