Description Not Available
Soil water retention at field capacity and permanent wilting point are important for recognizing plant
available water potential and plant water stress in specific soil type. Using the relations between soil
moisture contents, soil particles and bulk density, the pedotransfer functions (PTFs) were developed and
simulated for soil moisture estimation at 0.033 and 1.5 MPa pressure head in fifty nine soil samples.
Based on t-test, the developed PTFs were screened. Performance of the screened PTFs was evaluated by
testing through R2
– statistics, residual error values, coefficient of residual mass and model efficiency
estimate. These established PTFs provides useful alternative to simulate point soil moisture content
values from easily measurable relevant soil parameters.
