Liquid Nanoclay Technology for Rapid Soil Amendment in Arid Environments: Electrostatic Mechanisms, Hydrological Performance, and Agricultural Viability

This doctoral-level investigation examines the innovative application of liquid nanoclay (LNC) technology for rapid soil transformation in arid environments, with particular focus on the March 2020 field trials conducted in the United Arab Emirates. Through independent verification by the International Center for Biosaline Agriculture (ICBA), this technology demonstrated the capacity to convert barren sandy substrates into productive agricultural land within 40 days, achieving water-use efficiency improvements of up to 47% while generating 200 kg of produce from a 1,000 m² experimental plot. This paper elucidates the fundamental physicochemical mechanisms underlying LNC performance, including Van der Waals and electrostatic binding between negatively charged clay nanoparticles (200–300 nm coating thickness) and positively charged sand grains. Drawing parallels to the millennia-old fertility mechanisms of the Nile Delta prior to the Aswan Dam construction (1960s), we analyze how this biomimetic approach addresses contemporary desertification challenges.
