Humic and fulvic acids are both products of decomposed organic matter, but they behave differently. Humic acid molecules are larger and work mainly on soil structure and long-term nutrient retention. Fulvic acid molecules are smaller, more mobile, and better at carrying nutrients directly into the plant.
It binds soil particles into stable aggregates. That improves porosity, water infiltration and root penetration — and in compacted or heavily worked soils, this structural effect is often what unlocks a better fertiliser response.
Because it is small enough to pass through cell membranes, fulvic acid acts as a natural chelator: it binds nutrients and helps transport them into root tissue. Nutrients that might otherwise stay locked in the soil become genuinely available.
Both acids increase cation exchange capacity — in plain terms, the soil's ability to hold onto nutrients instead of letting them wash away. Under Malaysian rainfall, leaching is one of the biggest sources of wasted fertiliser spend, and this is a direct counter to it.
NEXGROW is formulated with over 20% humic and fulvic acid content, alongside more than 50% organic matter and phosphate-solubilising bacteria — the structural, transport and biological pieces working together rather than in isolation.
These are not fertiliser substitutes. They make nutrition work better; they do not replace the nutrients themselves.
Soil Testing & Lab Analysis — texture, pH, nutrients and organic matter, with a written programme.
NEXGROW brings phosphate-solubilising bacteria, humic & fulvic acids and natural growth hormones into one bio-organic fertiliser, processed in line with MS 1517:2012.
