Farm Spray & Tank Mix Calc

Mix every tank right: dose times area gives product per tank, water and the partial last fill. Nozzle calibration included. Works offline in the field.

The farmer's spray calculator — dosing, tank mixing and nozzle calibration in one honest tool.

Enter the label dose and your field size to get the exact amount of product to buy. Plan every sprayer fill: product and water per tank, tanks needed for the whole field, the area each tank covers and the partial last fill — ready to read back at the water source. Work in decares or hectares; dose, rate and area all follow one global unit.

PRO • Nozzle calibration: enter nozzle flow, ground speed and spacing to get your real application rate (the 600 formula) in L/ha and L/da • Mix a second product in the same tank • Quick converters: decare ↔ hectare, liter ↔ milliliter, % ↔ g/L • Save named recipes to history • Share clean PDF recipe cards

Built for gloves and sunlight: big keypad, huge results, Outdoor Bright mode.

Everything stays on your phone — fully offline, no account, no tracking.

Always follow the product label — the label is the law.
