Description

Application

• Foliar applied potassium nanoparticles (K-NPs) and potassium sulfate on growth, physiological, and phytochemical parameters in Melissa officinalis L. under salt stress.: This investigation assesses the effectiveness of potassium sulfate in alleviating salt stress in plants, focusing on its role in enhancing growth and stress tolerance. The study provides valuable data for improving crop resilience to salinity, a growing issue in global agriculture (Nanehkaran FM et al., 2024).


• Effects of Potassium-Containing Fertilizers on Sugar and Organic Acid Metabolism in Grape Fruits.: Examining the role of potassium sulfate in grapevine nutrition, this research elucidates its impact on the metabolic pathways involved in sugar and organic acid production. The outcomes are significant for viticulture, offering strategies to enhance fruit quality and vine health (Wang J et al., 2024).


• The combination of chemical fertilizer affected the control efficacy against root-knot nematode and environmental behavior of abamectin in soil.: This study investigates how potassium sulfate, when used in conjunction with other fertilizers, influences the efficacy of pesticides and the soil′s environmental dynamics. The findings are crucial for developing integrated pest management strategies that are environmentally sustainable (Jiang J et al., 2024).
