Abstract:

A Study was undertaken to evaluate the fertility status of Nignoti village, Indore district, Madhya Pradesh covering a village during 2013-2014. The systematic collection of samples in geo–referenced surface (0-15cm) soils was done from 250 sites representing Vertisols and associated soils. The samples were analyzed for Mechanical composition of soil viz., Sand, Silt, Clay and chemical composition viz., pH, EC, O.M., and analyzed the different forms of potassium viz., water soluble K, exchangeable K, available non exchangeable K, lattice K, total K. The texture of the soils of Nignoti village of Indore district varied from clay loam to clayey which is neutral to slightly alkaline in nature and found normal in respect of soluble salts. Organic carbon status of Nignoti village was found in the range of 0.22 – 0.76 % under different farmers field with the average value of 0.49 %. It is clear from the results, that more than half samples (50.8 %) of village show medium status and 47.6 percent soil samples show low status of organic carbon content in different farmer’s field. The amount of water soluble, exchangeable, available, non-exchangeable, lattice and total-K in Nignoti village of Indore district; ranged from 0.008 – 0.051, 0.251 – 0.975, 0.266 – 1.012, 0.625 – 2.987, 21.818 – 45.883 and 23.515 – 49.640 me/100g with the mean value of 0.019, 0.550, 0.569, 1.463, 32.522 and 34.574 me/100g respectively. Under different soil profiles, the water soluble, exchangeable, available and non-exchangeable forms of potassium decreased with depth. Whereas, total –K and lattice-K did not show any define trend with depth. The exchangeable K showed significant and positive correlation with organic carbon content and clay particles of the soils. A highly significantly and positively relationship were observed between different forms of K, These relationships indicate that there existed equilibrium between these forms of K and depletion of one is instantly replenished by one or more of the other forms of K.
