Assumptions & method
- Nutrients applied = rate (kg/ha, or L/ha × density) × analysis % w/w. Trace elements are shown in g/ha.
- Lime & amendments supply Ca, Mg, Na and S = t/ha × 1000 × element %. Pure CaCO₃ equivalent = rate × NV × fineness efficiency.
- Lime indicated = (target pH − soil pH) × texture factor (0–10 cm) + one year of program acidification.
- Fertiliser acidification (kg lime/kg N) = product base value + 1.8 × nitrate leaching fraction.
- Spray quantities: /100L and % v/v rates are converted using the water rate. Per-tank amounts use the tank size.
- pH values are pH(CaCl₂). All defaults are indicative. Always follow product labels and permits.
