Abstract
An investigation on the moisture retention characteristics of alluvial soils
of Kerala was carried out in the College of Horticulture, Vellanikkara, during
1982-'83, using soil samples collected from different parts of the state. Moisture
retention was measured at six tensions and a prediction model was developed for
moisture characterisation. More than 70 per cent of the available water was found to be removed at a tension of 3 bars. The moisture contents of different tensions
were correlated to the contents of organic carbon and textural components. Organic
carbon content showed no significant correlation with moisture retention. The
textural components were apparently the determining factors for moisture retention
as indicated by the significant positive correlation with the fine fractions (clay and
silt) and significant negative correlation with the coarse fractions {fine sand and
coarse sand). Multiple regression equations were developed to predict the available
water content and moisture contents at 0.3 and 15 bar suctions from the
contents of organic matter and textural components.
