  • Synergistic and non-synergistic impact of HAP-based nano fertilizer

    Synergistic and non-synergistic impact of HAP-based nano fertilizer

    Abundant use of nitrogenous fertilizers leads to wasteful expense and environmental degradation through excessive urea availability. We synthesized urea-hydroxyapatite nano fertilizer (UHAPF). Through characterization, we revealed controlled nitrogen release due to reduced hydroxyapatite (HAP) dissolution.

  • Promote root growth and seedling growth

    Promote root growth and seedling growth

    Water-soluble NPK fertilizers with high nitrogen and phosphorus macroelements need to be effective quickly and have significant differentiation. It is recommended to use AOS to increase the effectiveness. In view of the function of highly active AOS, it is recommended to add 1kg per ton to high-nitrogen and high-phosphorus NPK fertilizers to quickly take root, improve stress resistance and disease prevention effects, and is easy to add, safe and scientific and efficient.

    Nano fertilizer synergist eects onnitrogen utilization andrelated gene expression inwheat

    Nitrogen (N) is one of the essential elements for crop growth, which can regulate many processes of wheat (Triticum aestivum L.) growth and development. e application of chemical fertilizers plays an important role in optimizing yield and quality of crops. Accord-ing to statistics, the domestic application of chemi-cal fertilizers accounted for nearly 40% of the World’s application in 2011, and has been growing [1].
