Soil water potential at hygroscopic potential is
Water available between field capacity and permanent wilting point is called as
-
Solution
Available Water Water activity of available is a measurement of water content. It is defined as the vapour pressure of a liquid divided by that of pure water at the same temperature therefore pure curtailed areolar has a water activity of exactly one.
Water held in micro pores (at soil water potential of – 0.1 to – 0.15 bar) and most of water taken by plants is called
Water in excess of field capacity is termed as water.
Soil water potential of permanent wilting point/wilting coefficient is
-
Solution
Permanent Wilting Point Permanent Wilting Point (PWP) or Wilting Point (WP) is defined as the minimal point of soil moisture the plant required not to wilt. If moisture decreases to this or any lower point a plant wilts and can, no longer recover its turgidity when placed in a saturated atmosphere for 12 h.
Factor influencing the flow of water under saturated condition is.
One bar is equal to
Soil water potential is expressed in terms of
