Start / Water and irrigation
Irrigation depth and interval, irrigation time, flow needed per hectare, depth in mm and m³/ha, and water quality through salinity.
Calculate crop evapotranspiration, the water available in the soil, the irrigation interval, the gross depth and the system's irrigation time.
Interval, depth and irrigation timeCalculate the specific flow rate in L/s per hectare and the total system flow rate from the gross depth and the daily irrigation time.
Specific flow in L/s/haConvert the irrigation depth in millimetres into L/m², m³ per hectare, total area volume and litres per plant, using the crop spacings.
Converts mm into L/m², m³/ha and L per plantCalculate the SAR, the salinity and sodicity class of the irrigation water and the leaching fraction needed for your crop.
RAS, Richards class and leaching fractionImportant notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods. They do not replace a design, a calculation report or a report signed by a qualified professional (CREA/ART), nor verification against the applicable technical standards and legislation, such as the Regulatory Standards of the Ministry of Labor. Material and fuel properties vary: check with the manufacturer or with analyses of your process before deciding. By using the site, you agree to the Terms of Use.
