Benefits describe the intended support functions of the formulation. Response depends on soil, crop, nutrition and growing conditions.
03 / NITROGEN SCENARIOS
From nitrogen efficiency
to litres and dollars.
Compare a hypothetical reduction in leaching, or enter nitrogen recovery percentages from your own scenario. The calculator keeps these two measures separate.
Your liquid program
0.422 kg N/L is a UAN example, not every liquid N product. Prices are examples. 2 L/ha is an example within the label’s 1–3 L/ha broadacre range. Confirm the current label for your program.
YOUR SCENARIO
Additional N retained—
UAN nitrogen applied
AdGreen required
Mix ratio
Nitrogen remaining after leaching
Potential crop-value gain
Extra AdGreen program cost
Value above / below cost
Could the same N outcome use fewer litres?
Simplified equal-outcome calculation: assumes the entered loss or recovery percentages stay constant when UAN rate changes. It is not a rate recommendation. Do not add this saving to the extra-N value above.
CROP RESPONSE / THREE PROGRAM OPTIONS
AdGreen or “just add more UAN”?
Compare crop revenue after diminishing N response and an optional, hypothetical root-zone stress penalty. The same stress rule applies to every option. No toxicity protection is assigned to AdGreen.
Crop response assumptions
Starting values illustrate a curve; they are not a canola recommendation or an AdGreen trial fit. Use your paddock response data.
This is a sensitivity test, not a validated toxicity model. High nitrate salt concentration, ammonia/ammonium injury and nutrient imbalance are different issues. No universal nitrate-N injury threshold is assumed.
Uses the contact soil mass from “Soil & placement” below. The 25% nitrate fraction is an initial UAN example; nitrification and time can change it. This loading proxy excludes transport, sorption, uptake, moisture and salt composition. It is not a soil-solution concentration or measured nitrate exposure. The same rate gives the same initial loading with or without AdGreen.
POTENTIAL MARGIN DIFFERENCE
AdGreen compared with extra UAN—
Current efficiencyAdGreen scenario efficiencyMore UAN point
Modelled yield versus UAN L/ha. Curves use the same crop response and, if enabled, the same stress rule. More UAN keeps baseline efficiency; AdGreen uses your entered efficiency, not a dose-response function.
How yield, stress and ROI are calculated
Effective fertiliser N = applied UAN × kg N/L × entered efficiency. In leaching mode, multiply retained N by crop-capture %. Recovery mode already represents crop recovery, so the additional capture factor is not used. Yield before stress = starting yield + (yield ceiling − starting yield) × [1 − exp(−ln(10) × effective N / N90)]. This is an illustrative saturating response, not a calibrated crop model.
If enabled, nitrate-N loading = background mg/kg + applied UAN × kg N/L × nitrate fraction × 1,000,000 ÷ contact soil kg/ha. Hypothetical penalty = minimum(maximum penalty, excess mg/kg / 100 × penalty slope). Final yield = unstressed yield × (1 − penalty/100). This same rule applies to baseline, AdGreen and additional UAN.
Crop-value gain = (option yield − baseline yield) × crop price. Value above/below cost = crop-value gain − extra program cost. Baseline cost is current UAN cost; AdGreen adds its product/pass costs; more UAN adds extra litres/pass costs. Program margin = crop revenue − these N program costs only. It is not whole-farm profit. Do not add nitrogen replacement value to crop-value gain.
Setting additional UAN to match effective N equates N supply before the stress adjustment; it does not necessarily match final yield. With identical effective N and no stress, both options give identical modelled yield, so the lower extra cost wins. Near the yield ceiling, the response to additional effective N diminishes. AdGreen can also increase retained root-zone N; it is not assumed to remove toxicity risk.

Calculation basis & what NUE means
Recovery NUE = crop uptake of fertiliser-derived N ÷ fertiliser N applied × 100. Enter recovery estimates or measured values from a valid fertiliser-N recovery assessment; ordinary total crop N uptake includes soil-derived N. A treatment-minus-zero-N estimate is apparent recovery and should be identified as such.
Leaching mode: extra N retained = UAN L/ha × kg N/L × baseline loss fraction × relative loss reduction. The remaining N is not a crop uptake or yield prediction. Recovery mode: extra N recovered = applied N × (scenario recovery − baseline recovery). Relative improvement is the gain divided by the baseline outcome; percentage points are the difference in percentages.
Potential replacement value = extra N ÷ UAN kg N/L × UAN price × useful fraction. Treatment cost = AdGreen rate × price + extra application cost. Other N losses and crop uptake may limit realised benefit. AdGreen dose changes product requirement and cost here; no measured AdGreen dose-to-NUE function has been supplied.
04 / SOIL & PLACEMENT CALCULATOR
Define the contact zone.
Understand the holding capacity.
Define your application placement using width, thickness and row spacing, or individual wetted zones. Explore the theoretical added exchange charge only when you have a measured AdGreen capacity.
Use results for comparable pH, ionic strength and test method. No AdGreen product-capacity result has been supplied; these fields intentionally start blank. Organic carbon or total humate percentage alone is not exchange capacity.
The 2 L/ha example is within the label’s broadacre range. Soil dimensions and density remain editable assumptions.

Holding capacity is not nitrate storage
Negative exchange sites can associate with ammonium, calcium, magnesium and potassium. They are shared, competing sites. The NH₄-N equivalent assumes every added exchange site is occupied by ammonium; it is an upper-bound charge conversion, not a forecast of extra N retained.
Nitrate is negatively charged and moves with water. Added CEC does not directly bind it. Water-holding capacity also needs its own measurements; this calculator does not predict extra millimetres of water stored.
Soil-zone calculation method
Continuous band volume = 10,000 m²/ha ÷ row spacing (m) × width (m) × treated thickness (m). Individual-zone volume = width × length × thickness × number/ha. Whole-layer volume = 10,000 × thickness. Soil mass = volume × bulk density × 1,000 kg/m³. Dimensions must not imply overlapping zones or more than a hectare of surface.
Added charge (cmol(+)/ha) = AdGreen L/ha × measured cmol(+)/L. With dry-active inputs, cmol(+)/L = active g/L ÷ 1,000 × active CEC cmol(+)/kg. Local addition = added charge ÷ treated soil kg. Whole-layer addition uses all soil in that thickness across a hectare. Upper-bound ammonium-N equivalent = added charge × 0.000140067 kg N/cmol(+).
This additive charge model assumes all measured product capacity remains accessible in the defined zone. It does not model pH, sorption, degradation, cation competition or changes in measured soil CEC. It does not calibrate a nitrogen loss reduction. Small contact volumes amplify local concentration without creating extra total exchange sites.

What is in AdGreen?
The supplied brochure describes a combination of organic acids, amino acid complexes, nonliving Trichoderma harzianum metabolites and trace elements. The metabolites are not a live microbial inoculant.
How should I mix and apply it?
Confirm compatibility of the complete mix before use. Use the current label and advice for your crop and fertiliser program. Jar-test new combinations using the actual water and mixing order. Confirm compatibility before combining with strong acids or crop oils. Packs: 20 L, 110 L and 1,000 L.
Safety and storage
Avoid contact with eyes and skin. If swallowed, do not induce vomiting. Contact the Poisons Information Centre on 13 11 26 or a doctor. Store closed in a cool, dry, well-ventilated area away from direct sunlight. Refer to the current SDS for full safety directions.
What do the calculators demonstrate?
The application planner calculates product volume, cost and trace-element delivery. The nitrogen and soil tools explore user-entered scenarios. They do not predict a measured AdGreen response, prove a nitrification-inhibitor effect or assume a relationship between dose and NUE.
No finished-AdGreen field trial has been supplied to calibrate the scenarios. Component research and evidence from other formulations do not establish the yield response of this blend.
