Free tools for water management. Calculate irrigation volumes, schedule applications, size pumps, and optimise water use efficiency for crops and pasture.
Calculate total water volume in megalitres and litres for any area and application depth.
Calculate →Calculate days between irrigations based on crop water use, soil type and application depth.
Calculate →Calculate flow rates, tape spacing and run times for drip irrigation systems.
Calculate →Calculate application depth, speed settings and water use for centre pivot irrigators.
Calculate →Calculate water requirements and application efficiency for flood/border check irrigation.
Calculate →Efficient irrigation separates profitable farms from struggling ones. A 10% improvement in irrigation efficiency can save 50-100 ML per 100 hectares — worth $15,000-30,000 in water licence value. Use these calculators to measure, optimise and budget every megalitre.
