3、Extraction and characterization of fulvic acid from corn straw compost
The fulvic acid extraction was optimal at 70 ℃ when using the citric acid-ethanol method (Gong et al., 2022a), which different extraction methods and raw materials might cause.
Soil Microbial Co
The increasing amount of agricultural applications of controlled-release urea (CRU) and fulvic acids (FA) demands a better understanding of FA’s effects on microbially mediated nitrogen (N) nutrient cycling.
Effects of controlled
A split-plot field experiment was conducted in 2018–2019 to study the effects of nitrogen fertilizer types and fulvic acid (FA) rates on soil nitrogen and cotton growth.

The combined application of controlled
Controlled-release urea (CRU) and fulvic acid (FA) could improve nitrogen (N) use efficiency (NUE) and crop yield. This study aimed to reveal the synergistic interactions between CRU and FA on NUE, soil nutrient supply, and maize (Zea mays L.) yield.
The Combined Application of Urea and Fulvic Acid Regulates Apple Tree
In summary, the appropriate application of FA150 (urea + 150 kg ha−1) synergistically optimized C and N nutrient distribution, and promoted anthocyanin biosynthesis in apple trees.

[Effects of different fulvic acid application rates on fruit yield
To explore the effects of different fulvic acid application rates on 15 N-urea absorption, utilization, residue amount, loss and fruit yield and quality, fifteen-year-old 'Red General'/ Malus micromalus Makino was selected as experiment material by using the 15 N-labeled tracer technique.
Urea and potassium fulvic acid are both commonly used fertilizers, but their application methods and precautions differ.
Firstly, regarding application methods, urea is a nitrogen fertilizer primarily used to increase the nitrogen content in plants and promote growth. When applying urea, it is typically spread or applied in furrows, distributing it evenly over the soil surface or into channels before tilling to ensure thorough contact with the soil. The dosage of urea generally depends on the plant's growth stage, soil conditions, and climate. Typically, the amount of urea should not be excessive to avoid fertilizer damage.
Potassium fulvic acid, an organic fertilizer rich in various organic acids and mineral elements, mainly improves soil structure, enhances water and nutrient retention, and boosts plant absorption capacity. When using potassium fulvic acid, it can be mixed with chemical fertilizers or applied alone. When combined, it is spread or furrow-applied together with chemical fertilizers followed by tilling; when used alone, it is directly sprinkled on the soil surface or into furrows before tilling. The dosage of potassium fulvic acid also depends on the plant's growth stage, soil conditions, and climate. Generally, excessive use should be avoided to prevent compromising soil aeration and drainage.
Secondly, concerning timing, urea is usually applied during the early growth stage or peak growth period to accelerate plant development. Potassium fulvic acid can be applied at any growth stage to improve overall plant health and stress resistance.
Lastly, regarding application rates, urea dosage is determined based on the plant's growth stage, soil conditions, and climate. For potassium fulvic acid, the amount depends on soil fertility and plant requirements. Excessive use should generally be avoided to maintain soil permeability and drainage.
although the application methods of urea and potassium fulvic acid differ, both aim to enhance plant growth quality and yield. In practice, the application rates and methods should be adjusted according to the plant's growth stage, soil conditions, and climate to achieve optimal results.
