In 2022, scientists covered soil with 5 to 10 millimetres of wax-coated sand, slowing evaporation and increasing crop yields by up to 73%

Researchers have pioneered a groundbreaking water-repellent sand designed to mitigate agricultural water loss effectively. This innovative treatment not only dramatically decreases soil evaporation but also enhances moisture retention. Remarkably, even crops irrigated with brackish water experienced significant yield improvements. As a biodegradable alternative to traditional plastic mulch, this eco-conscious solution holds the promise of boosting food production while conserving water in arid regions.
