Provided herein are agricultural compositions, kits, and methods for improving crop productivity and enhancing plant phenotypes. Generally, the compositions and kits comprise an osmoprotectant and one or both of an anti-desiccant and an anti-respirant. Additional compositions and kits are provided that comprise an anti-dessicant and an anti-respirant. Further compositions and kits are provided that comprise a first osmoprotectant and a second osmoprotectant, the first and second osmoprotectants being different from one another. The methods provided herein generally comprise exogenously applying the agricultural composition to a plant.

An iterative approach to dynamic covalent polymerizations of elemental sulfur with functional comonomers to prepare sulfur prepolymers that can further react with other conventional, commercially available comonomers to prepare a wider class of functional sulfur polymers. This iterative method improves handling, miscibility and solubility of the elemental sulfur, and further enables tuning of the sulfur polymer composition. The sulfur polymers may be a thermoplastic or a thermoset for use in elastomers, resins, lubricants, coatings, antioxidants, cathode materials for electrochemical cells, and polymeric articles such as polymeric films and free-standing substrates.

Provided herein are compositions and methods to improve plant resistance to abiotic and biotic stress, thereby improving crop yield. Provided herein are compositions including zinc, copper, and an acid, where the acid is selected from citric acid, sulfuric acid, oxalic acid, humic acid, fulvic acid, boric acid, acetic acid, and a combination thereof. Certain embodiments optionally include ammonium sulfate. Compositions described herein have plant priming activity where the plant's defenses against abiotic and biotic stress are boosted.
