ICAR-Central Soil Salinity Research Institute, Regional Research Station, Canning Town, South 24 Parganas, West Bengal-743329, India.

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.

Key words: Sorptivity, salinity, humic acid, landforms.
