Info

• Rainfall needs to be factored into the water requirement equation. • The irrigation requirement to satisfy plant requirements can then be expressed by: Net Irrigation Requirement (IR) in mm = ET – Effective Rainfall • Due to inefficiencies, the sprinkler system needs to apply more water than the estimated irrigation requirement (IR). • The water required can then be calculated as follows: Water required in mm = Net Irrigation Requirement (IR) System Efficiency (use 80% as a
Soil Moisture Sensors • Soil moisture sensor technology can provide real time moisture levels within the soil profile. • Soil moisture sensors can provide; o Timing of irrigation o Rates of turf water use o Turf stress due to low moisture or water logging o Effectiveness of irrigation, rainfall and drainage rates Can be obtrusive in turf rootzones
