The importance of polyvinylpyrrolidone in modern agriculture

1. What is polyethylene pyrrolidone
Polyvinylpyrrolidone (PVP) is a kind of synthetic polymer, which is widely used in medicine, cosmetics and food industry because of its unique chemical stability, good solubility and non-reactivity. In recent years, due to these characteristics, PVP has also begun to play an important role in modern agriculture, especially in crop protection and yield enhancement.
The chemical properties of PVP make it an ideal excipient that can be used to improve the formulation of pesticides and fertilizers. It can effectively enhance the stability of the active ingredient and improve its adhesion and durability on the crop. This not only helps to improve the efficiency of the use of pesticides and fertilizers, but also reduces pollution to the environment, because less pesticides and fertilizers can achieve the desired effect.
In addition, the application of PVP in hydrogel technology is a major breakthrough. PVP based hydrogels can be used as intelligent release systems to precisely control the release of water and nutrients, which is especially important for crop growth in arid regions. This hydrogel technology not only improves irrigation efficiency, but also further optimizes resource use by reducing water and fertilizer waste. These applications of PVP demonstrate its versatility and environmental potential in modern agriculture. With the growing global demand for sustainable agricultural practices, these properties of PVP make it a key material to improve crop yield and quality while reducing environmental impact. By continuing to research and optimize the application of PVP and its composites, we can expect to achieve greater efficiency and lower environmental costs in agricultural production in the future.

2. Application of PVP hydrogel in agriculture
The application of polyvinylpyrrolidone (PVP) combined with polyvinyl alcohol (PVA) hydrogels in modern agriculture shows great potential for crop protection, precise fertilization and efficient irrigation. These hydrogels utilize their unique physicochemical properties to achieve continuous and controlled release of agricultural chemicals, thereby optimizing resource use and reducing environmental pollution.
Technical description of hydrogels
The hydrogels formed by the combination of PVP and PVA are realized by physical or chemical crosslinking. This structure is not only able to maintain a large amount of water, but also can control the rate of release of water and nutrients by regulating its network structure. For example, the mechanical properties of hydrogels can be enhanced through freeze-thaw cycles, making them more suitable for long-term use in agriculture (MDPI).
Multifunctional use
Crop protection
PVP hydrogel can be used as a carrier to evenly distribute pesticides on the surface of crops, reduce the loss and volatilization of chemicals, improve the control effect, and reduce the impact on the environment.
Precision fertilization
By controlling the release of fertilizer, PVP hydrogels help crops absorb nutrients more efficiently and reduce the overuse and loss of fertilizer, which is important for maintaining soil health and water cleanliness.

Water-saving irrigation
In arid or water-stressed areas, PVP hydrogels can absorb and store large amounts of water, which can then be gradually released as needed during crop growth, significantly improving irrigation efficiency and reducing water waste.
Through these applications, PVP hydrogels not only improve the efficiency of agricultural production, but also provide new solutions for agricultural sustainability. Their development and use demonstrate how traditional agricultural techniques can be improved through high-tech materials to adapt to the challenges posed by global change.
3. The role of PVP in improving crop yield
The use of polyvinylpyrrolidone (PVP) to improve crop yield and quality, especially in soybean cultivation, provides an example of significant improvements in agricultural efficiency. By combining with sodium alginate (Na-alginate), PVP has played a key role in the development of biological inoculants, significantly increasing the survival and activity of nitrogen-fixing bacteria, thereby enhancing soybean growth and yield.
Soybean planting case study
In soybean cultivation, the combination of PVP and Na-alginate is used to prepare a liquid inoculant containing the nitrogen-fixing bacterium Bradyrhizobiumjaponicum. This inoculant significantly improves bacterial survival and nodulation capacity because PVP provides a protective environment, reduces bacterial mortality during storage, and optimizes the interaction between bacteria and plant roots (MDPI).
Experimental result
In successive field trials, liquid inoculants prepared using PVP and Na-alginate significantly increased the number of nodules, pod number, seed number per pod, seed yield, and yield per hectare of soybeans. These results not only show the direct role of PVP in improving crop production efficiency, but also highlight its potential in promoting sustainable agricultural practices (MDPI).
Through these applications, the combination of PVP and Na-alginate creates a more effective biological vaccination system in soybean cultivation, which has a direct positive impact on improving the overall productivity and sustainability of soybeans. This innovative use not only improves crop yields and quality, but also provides a successful model for global soybean production that can be replicated, helping to address global food security.
4. Environmental advantages and future applications
The application of polyvinylpyrrolidone (PVP) in agriculture has not only improved crop yield and quality, but also demonstrated significant environmental benefits. These benefits are achieved by reducing the use of chemicals, optimizing resource management and enhancing the sustainability of agro-ecosystems. As the global demand for environmentally friendly farming technologies increases, the application of PVP is expected to expand to more agricultural practices.
Environmental impact
The use of PVP in crop protection and production can significantly reduce the reliance on traditional chemical pesticides and fertilizers. For example, PVP hydrogel technology reduces the overuse of fertilizers and pesticides through a controlled release mechanism, thus reducing the pollution that these chemicals can cause to the environment. In addition, PVP’s bioinoculation technology further reduces the need for fertilizer by increasing the efficiency of nitrogen use by plants, which is particularly important for protecting soil health and preventing eutrophication of water bodies (MDPI).
Enablers of sustainable agriculture
PVP’s technological innovations not only improve the efficiency of agricultural output, but also support the environmental sustainability of agricultural production. For example, PVP based hydrogels can effectively reduce water waste while maintaining soil moisture and nutrients. This technology is particularly beneficial in arid regions, helping to adapt to the challenges posed by climate change. In the future, with further research and development of new materials and technologies, PVP is expected to play a greater role in water-saving agriculture, organic agriculture and precision agriculture.
Through these applications, PVP not only provides immediate environmental advantages in actual agricultural production, but its role in promoting sustainable agricultural practices will be increasingly valued. In the future, as the demand for environmentally friendly agricultural technologies continues to grow, the development and application of PVP and its related technologies will continue to expand, contributing to the sustainable development of global agriculture.
