Alpha-ketoglutaric acid plays a very important role in modern agriculture, not only promoting the absorption of key nutrients by plants, but also improving the growth rate and yield of crops. The following is a popular science article on how to solve the problem of slow crop absorption and improve fertilizer efficiency.

　　α-ketoglutaric acid is an important organic acid in plants. As an intermediate product of the tricarboxylic acid cycle, α-ketoglutaric acid plays a key role in nutrient metabolism of plants. In recent years, it has been found that α-ketoglutaric acid can effectively promote the absorption of key elements such as nitrogen, phosphorus and potassium by plants, and thus improve the yield and quality of crops.

　　1. Mechanism of action of alpha-ketoglutaric acid

　　α-ketoglutaric acid is an important carbon skeleton and signaling molecule in plant ammonia assimilation process.

　　As a coenzyme of amino acid transaminase, it can participate in the synthesis and metabolism of amino acids, thereby enhancing the absorption and utilization efficiency of nitrogen sources in soil by plants.

　　This not only provides the nitrogen needed for plant growth, but also speeds up plant growth and increases yields.

　　α-ketoglutaric acid can also promote the absorption of phosphorus and potassium by regulating the growth and development of plant roots.

　　Phosphorus and potassium are a large number of essential elements for plant growth, and are crucial to physiological processes such as photosynthesis and energy conversion in plants.

　　By improving the structure and function of the root system, alpha-ketoglutaric acid helps plants acquire these elements more efficiently.

　　Second, the application of α-ketoglutaric acid

　　By adding α-ketoglutaric acid, the utilization rate of fertilizer can be improved, the amount of fertilizer used can be reduced, and the cost of agricultural production can be reduced.

　　This practice helps to reduce the environmental impact of fertilizers and is in line with the concept of sustainable agricultural development.

　　Promote crop growth α-ketoglutaric acid can stimulate growth hormone synthesis in plants, promote root development, and enhance plant stress resistance.

　　Accelerate the growth cycle of crops, improve crop yield and improve the quality of crops.

　　Improving soil health Alpha-ketoglutaric acid can also promote the growth of beneficial microorganisms and improve soil structure and fertility by improving the activity of soil microorganisms.

　　This helps build a healthy soil ecosystem and creates favorable conditions for long-term crop growth.

　　As a highly effective plant nutrient enhancer, alpha-ketoglutaric acid has shown great potential in promoting the absorption of key nutrients in crops and improving the utilization rate of fertilizers. With the deepening of research and technological progress, the application of alpha-ketoglutaric acid will be more extensive, providing strong support for achieving the goal of sustainable agriculture and ecological agriculture.
