Glycerol, also known as glycerol, is a colorless, odorless, hygroscopic, and well soluble compound. For a long time, glycerol has been widely used in industries such as pharmaceuticals, cosmetics, food, and chemicals. In recent years, with the continuous deepening of green agriculture and sustainable development concepts, the potential of glycerol in modern agriculture has gradually received attention, and its application scope and development prospects have shown broad space.

I. The application of glycerol in agriculture

1. Fertilizer additives

Glycerol can be used as a synergist and stabilizer in fertilizer production. For example, adding an appropriate amount of glycerol during the production of compound fertilizers can improve the adhesion and particle strength of the fertilizers, and reduce powdering problems during storage and transportation. Meanwhile, glycerol has certain water retention properties, which can help fertilizers slowly release nutrients in the soil and improve fertilizer utilization efficiency.

2. Pesticide carriers and enhancers

Glycerol is often used as a solvent and dispersant in pesticide formulations. It can not only increase the solubility of pesticide active ingredients, but also improve the uniformity of spraying, enhance the adhesion and permeability of pesticides on plant leaves, thereby improving the control effect. In addition, the low toxicity and degradability of glycerol make it a more environmentally friendly choice.

3. Plant stress inhibitor

Glycerol has strong hygroscopicity and water retention, and is considered a potential plant stress regulator. Under adverse conditions such as drought or high temperature, moderate use of glycerol can help plant cells maintain water balance, alleviate stress, and thus improve crop survival and yield.

4. Application in animal husbandry

Glycerol is also a commonly used energy supplement in animal feed. Research has shown that crude glycerol can partially replace energy sources such as corn feed, providing energy sources for ruminants and poultry, while also improving the palatability and storage performance of feed. This application indirectly serves the overall development of the agricultural production system.

II.The advantages of glycerol in modern agriculture

Firstly, glycerol has a wide range of sources. As a byproduct of biodiesel production, a large amount of crude glycerol is produced globally every year. How to efficiently utilize these by-products is the focus of industry attention. Using it in agriculture can not only reduce costs, but also alleviate environmental pressure.

Secondly, glycerol is environmentally friendly and green. It is non-toxic, biodegradable, and does not cause secondary pollution to soil and water bodies, which is in line with the development direction of modern agriculture's "ecological friendliness".

Again, glycerol has multifunctionality. From fertilizers to pesticides, from crops to animal husbandry, glycerol can play a role, demonstrating its good applicability and economic value.

III. Development prospects and challenges

With the advancement of agricultural modernization, the application prospects of glycerol are very broad. On the one hand, the global demand for efficient and environmentally friendly agricultural inputs continues to grow, and glycerol, as a renewable resource, is expected to play an important role in the green transformation of agriculture. On the other hand, the rapid development of the biodiesel industry will continue to provide low-cost glycerol raw materials for agriculture, promoting the research and promotion of related technologies.

However, the application of glycerol in agriculture still faces some challenges. For example, crude glycerol often contains impurities such as methanol, salt, etc. If used untreated, it may affect crop or animal health. Therefore, in the future, it is necessary to strengthen purification and standardization processes to ensure their safety and stability in agriculture. Meanwhile, the mechanism and effectiveness of glycerol in certain application scenarios still need further research and verification.

IV. Conclusion

In summary, glycerol, as a versatile renewable resource, has shown broad application prospects in modern agriculture. Whether as a fertilizer additive, pesticide enhancer, plant stress inhibitor, or feed additive, glycerol can play a unique role. With the advancement of technology and the improvement of the industrial chain, the application of glycerol in the agricultural field will be further expanded, providing strong support for promoting green agriculture and sustainable development.
