Mapping of spatial pattern of micronutrients in soils of Harda district of Madhya Pradesh through geo-statistical tool in arc gis environment

In present study GPS based three hundred three surface (0-15 cm depth) soil samples, were collected across the district. The Zn, and Fe deficient in 79.54% and 7.92 percent soil samples and none of soil samples were found to be deficient in Cu, Mn and B. Soil pH showed significant and negative correlations with Zn, Cu, Mn and Fe. The EC had positive and significant relationship with OC and B with r values of 0.163** and 0.168**, respectively. The significant positive relationship of OC of soil with available hot watersoluble B showing value of 0.164**. The micronutrients i.e. DTPA extractable Zn and Cu, Fe and Mn showed significant positive relationship with each other. HWS B was also found positive and significantly related with Fe (r=0.135*). Geo-statistical suggested that the exponential models best fitted for, Zn and B while spherical models for Cu, Mn, Fe. The nugget/sill ratios of semivariogram models for micronutrients were moderate. The having value were 0.78, 0.49, 0.44, 0.42 and 0.41 for Mn, Fe, Zn, B and Cu, respectively. | Mapping of spatial pattern of micronutrients in soils of Harda district of Madhya Pradesh through geo-statistical tool in arc gis environment
