NutriCharge, a technically advanced phosphorus and nitrogen fertiliser supplement from AgSupply, has been designed to deliver high concentrations of plant-available phosphorus with extended persistence in the soil profile, addressing the fundamental limitations of conventional phosphorus sources in high-fixation environments.

AgSupply’s Grant Morley says Nutricharge performance continues to impress.
“We have incredibly sound results in a rage of diverse crops – from sugarcane in Far North Queensland to potatoes in Victoria’s Gippsland, as well as pasture across that state and in broadacre crops across the whole country, from NSW to WA,” he says.
“What I have found is if you are using phosphorus the addition of Nutricharge can measurably help with the efficiency of these products.”
Grant says phosphorus also plays a central role in plant metabolic function, including ATP synthesis, photosynthate transport, root initiation, and early vegetative development.
However, he says in many agricultural soils, applied phosphorus is rapidly rendered unavailable through precipitation and adsorption reactions with calcium in alkaline soils and iron and aluminium oxides in acidic soils. This limits diffusion to the root surface and reduces overall phosphorus recovery by the crop.
“NutriCharge has been formulated using advanced stabilisation and delivery technology to mitigate these fixation pathways,” Grant explains.
“By maintaining phosphorus in a more soluble and plant-available form, NutriCharge enables sustained phosphorus availability across early establishment and rapid growth phases, improving synchronisation between nutrient supply and crop demand,” he says.
“From an agronomic perspective, NutriCharge increases phosphorus use efficiency by extending the functional lifespan of applied phosphorus in the rhizosphere.
“Improved availability supports rapid root elongation, increased lateral root density, and enhanced mycorrhizal activity, resulting in improved nutrient and moisture acquisition.
“These effects are particularly valuable in cold soils, compacted profiles, and high-pH or high-P-buffering capacity soils where early phosphorus availability is commonly constrained.”
Field observations indicate NutriCharge supports stronger early vigour, improved uniformity, and increased biomass accumulation compared to conventional phosphorus programs.
Enhanced root architecture allows crops to better tolerate abiotic stress.
Enhanced root architecture allows crops to better tolerate abiotic stress, including transient moisture stress and temperature variability, while maintaining nutrient uptake during critical growth stages.
Nutri Charge is compatible with a wide range of fertiliser programs and application systems and can be utilised across broadacre, pasture, and intensive cropping systems.
Its extended phosphorus availability reduces the risk of early-season deficiency and limits reliance on high upfront phosphorus rates, particularly in soils with high fixation potential.
By improving the proportion of applied phosphorus that remains agronomically effective, NutriCharge delivers measurable improvements in fertiliser efficiency and return on investment.
This positions Nutri Charge as a strategic tool for agronomists seeking to optimise nutrient programs under both economic and environmental constraints.
On top of its performance benefits, NutriCharge supports responsible nutrient management by reducing phosphorus losses to non-labile soil pools.
Improved efficiency contributes to long-term soil fertility management while aligning with best-practice nutrient stewardship principles.
“Nutricharge also helps your plants get the most out of the nitrogen in your soil,” Grant adds.
“Its patented nitrogen efficiency technology provides protection against nitrogen loss as it holds nitrogen in the ammonium form in the root zone, which requires the least amount of energy for the plant to take up, increasing the plants overall efficiency in utilising nitrogen,” he says.
AgSupply continues to invest in technically robust input solutions developed to address real-world soil and crop challenges.
NutriCharge provides agronomists with a high-performance phosphorus option that delivers sustained availability, improved uptake, and consistent crop response under variable soil conditions.
