应用
- Fertilizer application alters cadmium and selenium bioavailability in soil-rice system with high geological background levels: This study explores how different fertilizer applications, including potassium sulfate, affect the bioavailability of cadmium and selenium in rice cultivated in areas with naturally high levels of these elements (Zhou et al., 2024).
- Exogenous application of nano-silicon, potassium sulfate, or proline enhances physiological parameters, antioxidant enzyme activities, and agronomic traits of diverse rice genotypes under water deficit conditions: Research indicates that potassium sulfate, along with nano-silicon and proline, can improve water stress resilience in rice by enhancing physiological traits and antioxidant activities (Abd-El-Aty et al., 2024).
- Size-Independent Nucleation and Growth Model of Potassium Sulfate from Supersaturated Solution Produced by Stirred Crystallization: This paper presents a model of potassium sulfate crystallization that is independent of crystal size, providing insights into the controlled crystallization processes used in industry (Zheng, 2023).
- Prediction models of macro-nutrient content in plant organs of Cucumis melo in response to soil elements using support vector regression: This study includes potassium sulfate among the soil elements analyzed for their impact on nutrient uptake in melon, with models predicting how different soil treatments affect plant growth (Keshtehgar et al., 2023).
- [Effects of chemical fertilizer reduction and organic fertilizer substitution on yield and quality of Saposhnikovia divaricata]: This research evaluates the effects of reducing chemical fertilizers, including potassium sulfate, and substituting with organic options, highlighting changes in plant yield and quality (Li et al., 2023).
