2-Ketoglutaric acid effectively facilitates the absorption of essential elements such as nitrogen, phosphorus, and potassium in crops. Serving as a crucial carbon skeleton and signaling molecule in the ammonia assimilation process within plants, it acts as a coenzyme for amino acid transaminase, participating in the synthesis and metabolism of amino acids. This characteristic enhances the plant's efficiency in absorbing and utilizing nitrogen sources from the soil. By promoting nitrogen absorption, 2-ketoglutaric acid provides the nitrogen necessary for plant growth, thereby accelerating plant growth rates and increasing yields.
Beyond nitrogen, 2-ketoglutaric acid also promotes the absorption of phosphorus and potassium by regulating the growth and development of plant roots. Phosphorus and potassium are essential macronutrients for plant growth, playing vital roles in physiological processes such as photosynthesis and energy conversion. By improving the structure and function of root systems, 2-ketoglutaric acid aids plants in acquiring these elements more efficiently, thus enhancing the plant's overall growth status and yield stability.
Other roles of 2-ketoglutaric acid:
·Enhancing Fertilizer Utilization: Exogenous addition of 2-ketoglutaric acid can improve the utilization rate of chemical fertilizers, reducing their usage and lowering agricultural production costs. This practice also helps mitigate the environmental impact of fertilizers, aligning with the principles of sustainable agriculture.
·Promoting Crop Growth: 2-ketoglutaric acid stimulates the synthesis of plant growth hormones, promotes root development, and enhances plant stress resistance. These effects collectively accelerate the crop growth cycle, increasing crop yields while improving crop quality.
·Improving Soil Health: 2-ketoglutaric acid can also improve soil microbial activity and promote the growth of beneficial microorganisms, thereby enhancing soil structure and fertility. This contributes to establishing a healthy soil ecosystem, creating favorable conditions for long-term crop growth.
In practical agricultural production, 2-ketoglutaric acid can be applied to crops through foliar spraying or root irrigation. For instance, adding an appropriate amount to rice cultivation can significantly enhance the plant's drought and disease resistance, while promoting root growth, increasing tiller number and grain number per panicle, ultimately improving rice yield and quality.
As an efficient plant nutrient enhancer, 2-ketoglutaric acid demonstrates great potential in facilitating the absorption of essential elements such as nitrogen, phosphorus, and potassium in crops. With advancements in research and technology, its application in agricultural production will become more extensive, providing strong support for achieving the goals of sustainable and ecological agriculture.
