Fertilizer Sustainability: A Conceptual Framework for Assessing Equitable and Sustainable Soil Inputs

Sustainable Development, EarlyView.
ABSTRACT Modern industrial agriculture is predicated largely on the production and utilization of chemical fertilizers. Although this approach has played an integral role in increasing food security in many parts of the world, the long‐term sustainability of this resource‐intensive approach is questionable.

The Role of Oxophilicity and Water for Coordination Complexes as Ammonia Stores

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Exposing metal salts to humid ammonia leads to different products, which can be understood on the basis of the metal’s oxophilicity. Exposing copper vitriol to ammonia furthermore leads to the formation of single crystalline [Cu(H2O)(NH3)4]SO4 at ambient conditions.
