Biochemical Sources of Fulvic Acid and its Application in Agriculture

<p> The demand for crop yields is increasing in modern society. The challenges to agricultural cultivation, nevertheless, are posed by soil degradation, pollution, and the increasing number of extreme weather events due to climate change. All these factors can threaten crop yield and quality. However, fulvic acid can effectively alleviate these problems. It’s a type of humus with multiple agricultural values, is produced through biomass fermentation, and has various mechanisms that promote crop growth. It plays a significant role in mitigating various adverse factors affecting crop growth. Fulvic acid contains more carboxyl and hydroxyl groups but also the presence of ether bonds and ester bonds, due tothe special structure of xanthic acid, which also allows it to closely bond with many metal ions and substances. This paper provides an in-depth study of the mechanism and molecular structure of fulvic acid production and describes a variety of application scenes of fulvic acid in agricultural production. This paper makes a general conclusion on the improvement of yield and quality of yellow rot crops and analyzes the resistance of yellow rot to the adverse environment, including heavy metal hazards, salt stress hazards, drought hazards, pests, and diseases. Through the analysis by many scholars, yellow rot acid can play a significant role in the improvement of the adverse environment growing plants. </p> <p> Furthermore, the combined use of fulvic acid and modern drip irrigation techniques is receiving increased attention due to the significant benefits it offers in terms of water management and enhanced fertilizer efficiency. More studies should be conducted on the mechanism of xanthate in plants. The characterization of fulvic acid properties is indispensable in practical agricultural applications. Moreover, the development of effective fulvic acid derivatives according to the actual situation is essential to promote the sustainable development of agriculture.</p>
