“Humic acid ” is the commercial term often used to refer to the combined humic and fulvic acid content found in these naturally occurring deposits.
Humic acid is known to be among the most bio-chemically active materials found in soil.
How Does Humic Acid Improve Soil?
When applied to clay soils, humic acid can help break up compacted soils, allowing for enhanced water penetration and better root zone growth and development. When applied to sandy soils, humic acid adds essential organic material necessary for water retention thus improving root growth and enhancing the sandy soil’s ability to retain and not leach out vital plant nutrients.
