Frequently Asked Questions

  • Humic acid is a naturally occurring fraction of humic substances, which form as plant and organic material decomposes over time. It is commonly found in soils, composts, peat, and other forms of organic matter and is characterised by its complex molecular structure.

    In agriculture, humic acid is often discussed in relation to soil structure and nutrient dynamics. Due to its chemical properties, it can interact with minerals and nutrients such as nitrogen, phosphorus, potassium, and calcium, influencing how these elements are retained and move within the soil system. Humic acid is generally classified as a biostimulant material rather than a fertiliser.

  • Our humic acid is plant-based, meaning it is derived from renewable plant biomass rather than from fossil or geological deposits.

    Fossil humic acid is typically extracted from geological sources such as leonardite or lignite. These materials formed over long geological timescales and are widely used as sources of humic substances in conventional agricultural products.

    Both plant-based and fossil humic acid belong to the broader group of humic substances and share core chemical characteristics. They differ mainly in the origin and age of their raw materials. Fossil humic acid is derived from finite geological deposits, whereas plant-based humic acid is sourced from renewable biomass.

  • Our humic acid is produced exclusively from plants and has a purity of 97 %, which is uncommon among plant-based humic acid products currently available.

    Many commercially available humic acid products are fossil-based and sourced from materials such as lignite or leonardite. Their humic substance content can vary, and depending on the source and processing methods, they may contain trace mineral residues, including heavy metals, associated with mining.

  • Humic Acid: Powder form, commonly used for soil application or fertiliser blending.

    Potassium Humate: Liquid form, combined with potassium, commonly used for soil treatment and foliar sprays.

  • Humic acid is not classified as a fertiliser. It does not supply nutrients in the way mineral or organic fertilisers do. Instead, it is commonly described as a biostimulant material that is used alongside fertilisers and other soil inputs.

    In agricultural practice, humic acid is discussed in relation to soil processes such as nutrient dynamics and biological activity. For this reason, it is typically used as a supplementary product within broader soil and nutrient management strategies, rather than as a standalone fertiliser.

  • Humic acid cannot replace soil. It is used as a supplementary material within soil management practices and is applied alongside soil, compost, fertilisers, or other organic inputs.

    In agricultural contexts, humic acid is discussed in relation to soil properties such as structure, water relations, and nutrient dynamics. For this reason, it is typically used as part of broader soil management approaches rather than as a standalone input.

    In agricultural and land-use contexts, humic substances are discussed for their role within soil management approaches for degraded soils, including eroded or low-organic-matter systems. They are typically used alongside other amendments and management practices as part of longer-term soil improvement strategies.

  • Humic acid is used across a wide range of scales, from small gardens to professional agricultural and land-management settings.

    • In horticulture and hobby gardening, humic substances are commonly used as part of general soil and compost management practices.

    • In commercial agriculture, humic substances are used within broader soil and nutrient management systems, often alongside fertilisers and other inputs, and across a range of crop types and production scales.

    • Humic substances are also discussed in the context of land-use and environmental management projects, where they may be incorporated into soil management or rehabilitation approaches together with other measures.

  • Kyndra’s humic acid is distinguished by its source, composition, and specification.

    • Plant-based origin
      Our humic acid is produced exclusively from plants and derived from renewable biomass, rather than from fossil or geological deposits such as lignite or leonardite.

    • High humic acid content
      It is supplied with a humic acid content of 97%, which is uncommon among plant-based humic acid products currently available.

    • Non-fossil sourcing
      Unlike many humic acid products that are fossil-based and associated with mining processes, Kyndra’s humic acid is sourced from plant material and does not rely on finite geological resources.
