In this paper, spatial variability in soil chemical properties and fertility were investigated
in Bareli watershed, Seoni district of Madhya Pradesh. Georefened soil samples with a grid spacing of 325×325 m were collected in the study area and analyzed for soil pH, organic carbon, cation exchange capacity, available macronutrients (N, P and K) and
micronutrients (Fe, Mn, Cu and Zn). Spatial variability was quantified through
semivariogram analysis using geostatistics and kriged maps were generated in
eographic Information System (GIS). The results indicated that organic carbon was found to be highly variable followed by cation exchange capacity, while pH was found least variable. The soil fertility indicated that available K was found to be highly variable followed by available P, while available N was found to be least variable. All the micronutrients showed moderate variability. The spatial maps indicated that the available N, P and K were low to medium, medium to very high and medium to high, respectively. DTPA-Fe and DTPA-Zn was found deficient in 93.1% and 53.8% of area of the watershed. The reclassified kriged maps of soil fertility parameters generated from the point data clearly delineated different nutrient levels in the soils and very useful for site-specific nutrient management in the watershed.
