Phosphate is a building block of adenosine triphosphate (ATP), which serves a crucial role storing and transferring energy in the cells of all living things. In plants specifically, ATP is part of the photosynthesis process, and the ability to make plants grow big and strong with the application of essential nutrients like phosphorus through chemical fertilizers has been the foundation of our modern food system for almost a century.
