Liquid humic acid is a natural soil conditioner and plant growth stimulant with many benefits for plants and soil. Derived from humus, the most organic part of the soil formed by plant and animal matter decomposition, liquid humic acid offers a  sustainable way to enhance plant health and soil fertility. Here are the key benefits of liquid humic acid for plants and soil: 

Versatile Application: Liquid humic acid is easy to apply and can be used in various ways, including soil application, foliar spray, and as part of a nutrient solution. Its liquid form allows plants to absorb it and quickly take immediate action in the soil.  


Enhanced Nutrient Uptake: Humic acid has a high cation exchange capacity, which can hold onto nutrients and make them more available to plants. As a foliar application, liquid humic acid can directly interact with the leaves, absorbing nutrients more quickly than roots. This direct pathway to the plant's vascular system means that essential nutrients, chelated by the humic acid, are readily available for immediate use. This can be particularly beneficial during critical growth phases or when plants recover from stress and need a quick nutritional boost. 

Improved Growth and Yield: Humic acid stimulates plant metabolism, enhancing root development, shoot growth, and overall plant vigour. This often results in higher yields and better-quality produce.  

Increased Stress Tolerance: Plants treated with humic acid show increased resilience to stress factors such as drought, salinity, and extreme temperatures. This is due to improved water retention capabilities and enhanced nutrient absorption, which help plants withstand adverse conditions.

Enhanced Seed Germination: Applying liquid humic acid can improve seed germination rates by providing seeds with essential nutrients and creating a more favourable microenvironment.  

Improved Plant Health: The presence of humic acid can lead to stronger, healthier plants by boosting their immune systems, making them less susceptible to diseases and pests.


Improved Soil Structure: humic acid helps to bind soil particles into aggregates, improving soil structure. This enhances water retention, aeration, and root penetration, creating a better environment for plant growth.

Increased Soil Fertility: Humic acid enriches soil fertility by improving the soil's organic matter content. It supports the activity of beneficial microorganisms, which play a crucial role in nutrient cycling and organic matter decomposition.  

Enhanced Water Holding Capacity: Humic acid can significantly improve the soil's ability to retain water, reducing the need for frequent watering and helping plants during periods of drought.

Detoxification of Soil: It has the ability to chelate (bind) toxic metals and other harmful substances in the soil, reducing their availability to plants and mitigating potential damage to the ecosystem.

Promotes Microbial Activity: Liquid humic acid provides an energy source for beneficial soil microorganisms, promoting a vibrant, healthy soil ecosystem that is crucial for nutrient cycling and soil fertility.

This Humic acid is derived from Humalite, a highly concentrated source of Humic and Fulvic Acid found exclusively in Alberta, Canada.


Humic Acid is not 100% soluble in acidic water conditions but is soluble in alkaline solutions. In acidic mixes, it needs to be agitated to remain in suspension.

We use the “HPTA” testing method to report humic & fulvic acid content. The HPTA method is the ONLY analysis method recognized by the HPTA, the J-AOAC, and ISO capable of accurately measuring fulvic acid. Most suppliers of fulvic acid use outdated and inaccurate analysis methods in order to make higher fulvic claims. We have chosen the highest standard of analysis.
