The Sidhi District is situated on the North-eastern boundary of the Madhya Pradesh State, India which lies over a transitional area between the Indo-Gangetic plain in the north and the Deccan plateau in the south and the remotest district of Madhya Pradesh The systemic and comprehensive analysis of twenty composite samples of rainfed and irrigated agricultural soil around Sidhi district. The pH of soil samples varied from 6.6 to 8 especially and recorded higher values in the irrigated soils. The EC and CEC showed large spatial variation in the irrigated soils. The results showed alterations in the biogeochemical relationships between physico-chemical parameters. In rain fed areas, the high Si/Al and low Fe/Al ratios showed silicate nature of agricultural soils along with low iron loss from primary silicates.
