A study was conducted on the distribution of different forms of zinc (Zn) in soils (0–20 and 20–40 cm depths)in different blocks of Cooch Behar district, West Bengal,India. The soils of the selected areas were acidic in reaction (pH) at both the depths, ranging from 4.23 to 6.96 (0–20 cm) and 3.89 to 6.45 (20–40 cm) and having sandy to sandy loam texture. The different fractions of Zn varied among the soils of all locations. The order of different zinc fractions was: exchangeable zinc(Ex-Zn) < organic matter-bound zinc (OM-Zn) –1 at 0–20 cm depth and 0.92 kg ha–1 in the soils of Tufanganj-II at 20–40 cm depth respectively. Exch-Zn,OM-Zn, Mn-Ox-Zn and Am-Ox-Zn were positively correlated with CEC (r = 0.088, r = 0.105, r = 0.137, r = 0.103) at 0–20 cm depth, while at 20–40 cm depth, Exch-Zn, OM-Zn, Mn-Ox-Zn, Am-Ox Zn and Cry-Ox-Zn were positively correlated with CEC (r = 0.204, r = 0.168, r = 0.342, r = 0.123, r = 0.278). The influence of different soil properties on the distribution of Zn fractions in the soils was apparent from this study.Keywords
