Phosphorus cycling in organic systems
… The prohibition of synthetic fertilizer use in organic systems means farmers rely on crop rotation or approved inputs to supply P for crops. Legumes in crop rotation add P to soil through decomposition and deposition, and approved fertilizers such as bone meal (BM), rock phosphate (RP), and …

Aromaticity Across States: A Framework for Reactivity and Structure in Organic Systems
… the stability, structure, and reactivity of organic molecules. In the ground state, [4n+2] π-systems are stabilized by aromaticity, while [4n] π-systems are destabilized by antiaromaticity. Upon photoexcitation, these rules invert, as described by Baird’s rule, making aromaticity a dynamic …
