Soil infiltration in relation to organic matter and its humic
components namely, humic acid and fulvic acid for different soils coming under
different landforms namely, cultivated deltaic, non cultivated deltaic,
depressed land and mudflats were analyzed for a coastal Block (Gosaba) of West
Bengal, India. Results showed that organic carbon content of all soils were
medium (0.54%) to high (1.28%), salinity was low to high (3.6-13.7dS/m). The
steady state cumulative infiltration of cultivated deltaic soils were higher
than depressed low soils may be because of higher fulvic acid content in deltaic
soil (0.14-0.15%) than depressed soils (0.09-0.10%). The non cultivated deltaic
soil also showed higher fulvic acid content (0.11-0.13%) than depressed soil
(0.09-0.10%) The humic acid: fulvic acid ratio decreased with soil depth. The
relationships between steady state cumulative infiltration and EC, pH, clay,
porosity and humic acid were significant (r = -0.79*, -0.75*, -0.82*, -0.90**
and -0.93**, respectively), exponential and negative. With increase in soil
salinity, in general there was a decrease in organic matter content of all
soils.
