Description Not Available
Soil hydraulic properties are important for irrigation
scheduling and proper land-use planning. Field capacity,
permanent wilting point and infiltration rate
are the three vital hydraulic properties which determine
the availability and retention of water for crop
growth. These properties are difficult to measure and
time-consuming, but can be easily predicted from the
available information like soil texture, bulk density,organic carbon content, etc. through pedotransfer
functions (PTFs). PTFs were developed for field
capacity and permanent wilting point for two different
regions of Karnataka, viz. Northern Karnataka
Plateau (512 soil samples) and Southern Karnataka
Plateau (228 soil samples), separately. PTF for infiltration
rate was developed using 100 soil samples for
the entire Karnataka. Cross-validation techniques
were used to validate the PTFs, and the results are
satisfactory with low RMSE and higher R2. The developed
PTFs are useful in determining soil hydraulic
properties of the semi-arid regions of southern India
