H” Rice Low Land (1.31) H” Forest (1.22) H” Rice Upland (2.21) H” Orchard (1.15) > Fallow (1.01) (table 2). Distribution of Ws_K across the three depths of sampling were significantly different and followed the order: 0-15 cm (1.32) > 15-30 cm (1.17) H” 30-45 cm (1.14). These finding are similar with Naik et al., 2014.
Irrespective of ecosystem and depth of soil sampling the Ws_K content of Jhargram soil series was significantly positively correlated with pH (r=0.415), OC (r=0.633) and NEx_K (r=0.309) (Table 3).
In Saripbasa soil series, in orchard ecosystem the Ws_K was the lowest (2.42), it was the highest in Rice medium land ecosystem (3.54) (table 4). Under different ecosystem the Ws_K followed the order: Rice Medium Land (3.54) > Rice Low Land (3.26) H” Rice Upland (3.18) > Fallow (2.78) H” Forest (2.72) > Orchard (2.42). Distribution of Ws_K across the three depths of sampling were significantly different and followed the order: 0-15 cm (3.17) > 15-30 cm (2.99) > 30-45 cm (2.79).
Irrespective of ecosystem and depth of soil sampling the Ws_K content of Saripbasa soil series was significantly positively correlated with pH (r=0.501), OC (r=0.549), Ex_K ( r=0.431), NEx_K (r=0.591) and Av_K (r=0.459) and significantly negatively correlated with EC (r=-0.308) (Table 5).
