Land subsidence accelerated by underground coal extraction has great effect on soil quality. Although many studies have been done with respect to land subsidence effect on different properties of soil still studies on nutrient distribution of soil in subsided land are very few. This paper focuses on effect of land subsidence on distribution of soil micronutrients in a coal mining area. For this study six sites like unaffected sites, crack-1 site, slope-1 site, maximum subsidence site, crack -2 site and slope-2 site were chosen. The variation in content of soil micronutrients like iron(Fe), manganese(Mn),copper(Cu), zinc(Zn) were studied in the six sites. The effect of subsidence was found to be significant on the content of DTPA extractable Mn and Cu in soils of mining area at the depths of 0-15 cm, 15-30 cm and 30-45 cm. The highest DTPA extractable Fe and Mn content was observed in soils of maximum subsidence site at all the three depths. The subsidence had significant effect on the content of DTPA extractable Zn and Fe in soils of mining area at depth of 0-15 cm. Lowest Zn and Cu content was observed in soils of maximum subsidence site at all the three depths.
