$33.8$ mmol
$101.3$ mmol✔️
$202.5$ mmol

Agronomy QUESTION #2055

Question 2850

The permanent wilting point (PWP) of soil is the moisture content at which:

All gravitational water has drained from the soil macropores
Plants can no longer extract sufficient water from the soil and wilt permanently, corresponding to a soil matric potential of approximately $-1500$ kPa (or $-15$ bar)✔️
Soil moisture equals 50% of field capacity
Surface evaporation exceeds plant transpiration

Correct Answer Logic:

PWP is the soil moisture content at which the remaining water is held so tightly by soil particles (matric potential ≈ −1500 kPa) that roots cannot exert sufficient suction to extract it. Plants wilt permanently — they do not recover even when placed in a humid atmosphere. Plant-available water = FC − PWP.
