With irrigation scheduling, it’s not uncommon to increase yields by 5% or more!


Soil & weather data are key


The objective of irrigation scheduling is to plan and apply irrigation to maintain sufficient water in the soil to allow healthy crop growth. To do that, the irrigator must — at a minimum — estimate the crop’s water use and water-holding capacity of the soil.

Too much is as bad as not enough – The goal is to supply enough water to meet crop needs without exceeding the soil’s ability to retain the applied water and maintain that perfect amount. Irrigation in excess of the soil’s capacity to hold it means waste — it will drain to groundwater out of reach of the crop roots. A common error is to apply excess irrigation just to make sure there is enough to last a few extra days. Without knowing the soil’s water-holding capacity, this approach will waste water in a sandy soil and waste water while also drowning the crop roots in loam and clay soils.


Translating knowledge into action – Growers can also use estimates based on weather forecasts to plan irrigation. These water tools use estimates that are often available from university extension services and are adjusted for crop growth stage. Growers can check soil moisture by hand or by using sensors.

These resources exist, but turning crop water-use forecasts and soil moisture information into helpful irrigation recommendations takes expertise and training. This is where investment in scheduling technology can be a benefit.
