Wilchem is the only commercial program built across all four stages of nitrogen efficiency - monitor, establish, activate, convert. One connected range, formulated for Australian broadacre conditions, designed to extract more from every kilogram of fertiliser already in the ground.
Monitor what’s happening below the surface. Establish a foundation at seeding. Activate the biology that does the work. Convert the inputs already there into yield and protein.
Aquaspy
Real-time in-soil monitoring of moisture, nitrate movement and biological activity (redox/ORP) through the season. Shows where nitrogen is, where it’s going, and whether the biology is working.
Drives every decision. No more guesswork.
Rowloader
In-furrow conditioning and macro-nutrient delivery at seeding. Builds the soil chemistry foundation and supports crop establishment — the platform the biological program depends on.
Sets the foundation. Sets up success.
Biotics
Microbial biological inputs through the season. Supports the rhizosphere environment, improves nutrient cycling, and enhances the plant’s ability to access and use what’s already in the soil.
Builds the biological engine.
Signature
Amino acid chelated trace element nutrition. Addresses the conversion constraint — the speciality trace nutrition the plant needs to turn available nitrogen into protein and yield.
Closes the loop. Delivers yield and protein.
“How much nitrogen, and when?”
An important question — but only half the picture. It tells you what to apply, not whether your soil can convert it.
“Can the soil and plant system actually convert it into protein and yield?”
The factors that determine the answer — trace element availability, biological activity in the root zone, redox status — are the ones we’ve been working on for years.
A farm running the full Wilchem program will extract more from a reduced nitrogen budget than one cutting rates on a conventional program. That distinction matters in any season — and especially in a constrained one.
The four-stage journey above is built on this range. Each Wilchem product solves a distinct need — and because they’re all Wilchem, they’re formulated to work together across every broadacre crop.
Amino acid chelated micronutrients
Bidentate chelation creates a stronger bond than ionic - protecting the nutrient in solution, improving stability, and delivering better compatibility across complex tank mixes.
Soil conditioning & targeted nutrition at seeding
Wetters, penetrants, surfactants, electrolytes, tannins and complexing agents in a stable, non-toxic conditioner. Targets dispersive clay, surface sealing, infiltration and pH-driven lock-up.
A full-season biological program
Beneficial fungi and bacteria selected to improve nutrient cycling and uptake. A more functional soil, healthier crops, and more yield from inputs already being applied.
In-soil monitoring probes
The only commercial broadacre probe in Australia measuring nitrate, redox potential, moisture, temperature and EC. Tells you whether your nitrogen is still there and whether your biology is functioning.
High-analysis liquid sulfate fertilisers
The highest sulfur content of any micronutrient product on the market. Fully solubilised, settled and filtered. Zinc, manganese, copper - with custom ZMC blends including Mg, Fe, B and Mo.
EDTA chelated micronutrients
Sexadentate chelation - six bonds to the nutrient for maximum stability. The most compatible micronutrient on the market when tank-mix programs are most complex.
Making herbicides work harder
Liquid and crystalline APVMA-registered options that maximise the investment already being made in crop protection - simple in concept, significant in practice.
