Humic
What is Humic Acid?
Humic acid is a naturally occurring organic compound derived from Leonardite and Humalite, formed from plant and other organic materials over millions of years. It can help improve nutrient retention in soils struggling with nutrient loss. A key component of humic acid is carbon, which contributes to soil organic matter, supports soil function, and may increase fertilizer efficiency.
Humic acid is widely available in both liquid and solid forms, allowing for various application methods throughout the season (depending on soil conditions, crop rotations, and application timing).
Why use Humic Acid?
Humic acid has been used by farmers for decades, helping enrich soil by retaining and buffering nutrients in the root zone. In turn, this fertile soil can help support healthier, more substantial yields. Humic acid doesn’t replace nutrients found in fertilizer, but instead improves how efficiently these nutrients are used.
-
Nutrient Uptake
Humic acid contains negatively charged sites, allowing it to contribute to a soil’s cation exchange capacity (CEC). These sites help bind key soil nutrients, such as calcium, magnesium, and potassium, keeping them in the available root zone. -
Water Holding Capacity
Humic acid can help plants during periods of drought by enhancing moisture retention, as its hydrophilic molecules retain water molecules in the soil. -
Soil Aeration
Oxygen plays a crucial role in soil health, enabling respiration and nutrient absorption. Humic acid can help soil aggregates form, improving both structure and pore space.
