Fulvic acid is a type of organic acid naturally found in soil, compost, peat, coal (especially leonardite). It is a component of humic substances, which form during the decomposition of organic matter.

Fulvic acid is a natural chelator, binding to nutrients and making them more readily available for plant uptake. This improved nutrient absorption leads to enhanced growth, stronger root development, better drought resistance, and increased overall plant vitality and yield. It also stimulates microbial activity in the soil, further benefiting plant health.

Making fulvic acid fertilizer typically involves extracting it from humic substances found in highly decomposed organic matter like leonardite (a form of brown coal), peat, or compost. The most common method is through alkaline extraction, where the raw material is mixed with an alkaline solution (like potassium hydroxide) to dissolve the humic and fulvic acids. Then, the pH is adjusted (often with an acid) to precipitate the humic acid, leaving the more soluble fulvic acid in solution. This liquid can then be further purified and diluted to create a concentrated fulvic acid fertilizer.

In agriculture, fulvic acid acts as a powerful natural chelator, binding to essential nutrients in the soil and transforming them into easily absorbable forms for plants. This dramatically enhances nutrient uptake and efficiency, leading to stronger plant growth, improved root development, and increased yields. It also boosts stress tolerance against conditions like drought and salinity, improves soil structure and water retention, and stimulates beneficial microbial activity in the soil, ultimately contributing to healthier crops and more sustainable farming practices.

Yes, fulvic acid is very good for soil health and a vital component of fertile soil. It acts as a powerful natural chelator, making nutrients more available for plants by binding to them and preventing them from leaching away. This also improves the efficiency of fertilizers, potentially reducing the need for chemical inputs.

Beyond nutrient availability, fulvic acid also:

• Tăng cường cấu trúc đất by binding soil particles, leading to better aeration and water retention.

• Stimulates beneficial microbial activity, providing a carbon source that feeds microorganisms essential for nutrient cycling and overall soil vitality.

• Contributes to detoxifying soil by binding to heavy metals and pollutants, reducing their harm to plants.

Essentially, fulvic acid helps create a more balanced, living soil ecosystem.

Yes, fulvic acid does work, especially in agricultural applications, with a growing body of scientific evidence supporting its benefits. While the exact degree of benefit can vary depending on the source, concentration, and specific growing conditions, its positive impact on plant growth and soil fertility is well-recognized in the agricultural community.
