WC as distinct from Plant Available Water PAW PAW describes the amount of water extracted by a crop between the Field Capacity and the Permanent Wilting Point The Permanent Wilting Point is defined as the soil moisture content at which the crop is subjected to irreversible wilting During Phase 2 water is freely and readily available to the crop which does not experience any stress RAWC is preferred for use in irrigation scheduling because its defined lower limit Onset of Crop Water Stress is an exact irrigation trigger index of the crop that signals the onset of water stress from a crop s point of view This is in contrast to the arbitrary index such as 50 threshold of PAW which is an estimate and not a measurement of the crop s water need Phase 3 shows a declining water use by the plant The decline is specific to each crop and corresponds to the onset of yield and or quality reduction The boundary between Phase 2 and Phase 3 is the Onset of Crop Water Stress This is another key indicator for good irrigation management Sentek Pty Ltd ACN 007 916 672 Page 35 Part 1 The Diviner 2000 display unit and probe Irrigation scheduling using Diviner 2000 data The Onset of Crop Water Stress concept is the soil moisture content in the plant root zone when the first observable slow down of the maximum daily crop water use rate after irrigation or rainfall occurs This slowdown should not be caused by a change in weather cond
