Nanoscale sulfur can be a multifunctional agricultural amendment to enhance crop nutrition and suppress disease. Pristine (nS) and stearic acid coated (cS) sulfur nanoparticles were added to soil planted with tomatoes () at 200 mg/L soil and infested with . Bulk sulfur, ionic sulfate, and healthy controls were included.

- The study examined how citric acid-coated copper oxide nanoparticles (CuO NPs) affected soybean growth through different application methods (foliar vs. soil).
- Foliar application of CuO NPs significantly boosted soybean yield by around 170%, while no yield improvement was noted with ionic copper treatments.
- The results suggest that citric acid coating reduces CuO NPs toxicity, influencing copper accumulation and transfer in the plant, which has implications for food safety and nanoparticle usage.
Weedy rice grows competitively with cultivated rice and significantly diminishes rice grain production worldwide. The different effects of Cu-based nanomaterials on the production of weedy and cultivated rice, especially the grain qualities are not known. Grains were collected from weedy and cultivated rice grown for four months in field soil amended with nanoscale CuO (nCuO), bulk CuO (bCuO), and copper sulfate (CuSO) at 0, 75, 150, 300, and 600 mg Cu/kg soil.

- Understanding treefall disturbances in Amazonian forests helps us learn about species coexistence and predict future ecosystem changes.
- A study analyzed forests with different functional compositions, comparing their responses to treefalls by examining stem diversity and composition in both disturbed and undisturbed areas.
- Results showed a slight increase in stem numbers and alpha-diversity after disturbances, but these changes were minimal (2-4%) and consistent across various forest types, indicating that treefall events have a limited impact on overall forest diversity.
