Liquid Nanoclay– a new innovation produced by Norwegian startup Desert Control. Made with just water and clay, Liquid Nanoclay is designed to be sprayed on sand or sandy soil. It soaks in and attaches to sand particles, boosting water retention and enriching the soil with plant-essential nutrients.According to Desert Control, the mixture increases the fertility of nutrient-poor sandy soils and can reduce water usage by more than half. What’s more, Liquid Nanoclay can turn arid land into arable land in just seven hours, says the company.
