ABSTRACT

 

The water holding capacity of a soil is great value to practical agriculture, because it provides a simple means of determining moisture contents required for soils for good plant growth. Infiltration of water into soil is another important dynamic flow processes in the hydrological cycle. This information is used for water management and conversation studies. Hence a study was undertaken to determine the influence of soil physical properties on the infiltration characteristics and water holding capacity of major soils of Lalgudi Taluk, Trichy district, India. The soil properties such as bulk density, particle density, porosity, water holding capacity, and volume expansion were determined by keen- Rackzowski box for the four soil series of Lalgudi Taluk. The textural class of Irugur series was sandy loam, Poovalur series was silty clay and that of Pilamedu and Kallakudi series was clay loam. The final infiltration rate is highest (55.20 mm/hr) in Kallakudi series, which may be due to medium texture of the soil and low moisture content (1.84%). Among the four soil series, Pilamedu series recorded the lowest final infiltration rate value (33.6 mm/hr). The Kallakudi series showed a highest water holding capacity of 30.69%, which may be due to high clay content of the solids.
