Rock phosphate is valued for its phosphorus content, which is a crucial element for various biological processes in plants. Phosphorus is essential for energy transfer, root development, flower and fruit formation, and overall plant growth. It is a fundamental component of nucleic acids, ATP (adenosine triphosphate), and other vital molecules in plants.
