University of Glasgow develops £20 ultrasound device to produce fertiliser from air and water, aiming to help farmers in remote areas

• PC: University of GlasgowChemists and engineers have developed a £20 prototype device that uses ultrasound, water and air to produce nitrate, an important nutrient for plant growth.
• The technology could eventually allow farmers in remote areas to make fertiliser on demand, reducing their reliance on large industrial production facilities.
• According to a study by University of Glasgow researchers, published in Cell Reports Physical Science titled ‘Towards decentralized nitrogen fixation using pulsed ultrasound’, the process builds on a discovery that was first identified in the 1930s and uses s
