Abstract:

Surface (0-20) and sub-surface (20-40) soils from six different administrative blocks (Dhuluabari, Pundibari, Toofanganj, Mathabhanga, Dinhata and Sitai) of Cooch Behar district of West Bengal situated in terai region of Himalayan flood plain, India were analyzed to characterize the spatial distribution of different forms of potassium (K). The soils were acidic in nature, mostly sandy loam in texture and variable in organic carbon content and CEC. The corresponding distribution of K forms did not much varied in soils of different blocks in both the layers. The total K and constituently structural K were found higher in Dinhata surface soils as compared to other soils. However, available K was more in Toofanganj surface soils followed by Mathabhanga surface soils. All the K fractions were much lower in sub-surface layer than surface layer may due to the lower organic carbon, clay and CEC as they exhibited significant positive correlation with different forms of K. Predictability of K forms was much dependent of soil properties, mostly on organic carbon, clay and CEC.
