It stimulates cell division and promotes growth, encouraging root development. Soaking the seeds before planting in a concentrated solution of fulvic acid helps promote rooting by facilitating the formation of natural auxins for rooting and encouraging root primordia formation.

It works to treat soil salinity by enhancing the treatment of salinity in the soil. Fulvic acid helps mobilize soil calcium, making it active and easily accessible. Additionally, fulvic acid breaks the ionic bond of sodium chloride in the soil, allowing sodium to be washed out through leaching, reducing its impact on plants and aiding root absorption of nutrients from the soil.

It improves soil physical properties by darkening the soil, enhancing sunlight absorption, raising soil temperature, and stimulating root growth. Fulvic acid contributes to preventing soil calcification and cracking, preventing root damage, and increasing the osmotic pressure inside plants, making them more resilient to stressful and adverse growth conditions.
