The present investigation was undertaken with a view to evaluate the fertility status of Vertisols and associated soils of Golpura village in Dhar district of Madhya Pradesh and its relationship with important physico chemical characteristics for identifying the location specific conditions promoting nutrient deficiencies and realistic assessment of need for nutrients. The highlights of the investigation are summarized and concluded with following objective: to estimate the major nutrient status (N, P and K) and secondary nutrient(S) of the sampled soil, to assess the soil reaction (pH) and electrical conductivity (EC) and organic carbon in different soil samples of the study area, to study the micronutrients (Fe, Zn, Mn and Cu) status in sampled soil, to determine the textural class of sampled soils of the village and to quantify the relationship between organic carbon and available N content in soil through correlation. It can be concluded from the above results that the Soils of Golpura village in Dhar district of Madhya Pradesh were low in available N, low to medium available P and S, medium to high level in available K and characterized under neutral to alkaline in soil reaction (pH) and less than one d Sm-1 soluble salt content (EC) comes under safe limit for all soils. Out of total soil samples were tested high level DTPA-extractable Cu, medium level Fe whereas, Zn and Mn deficiency was observed in study area. The organic carbon level exhibited low to medium and positively significant correlation was exhibited amongst OC and available N. Most of the soils of Golpura village were characterized by Low, Medium and High categories. Hence, the soils require attention regarding nutrient management practices and regular monitoring of soil health for better crop production, in future. From the study, it can be concluded that, soils of Golpura village in Malwa Plateau Agro climatic zone of western Madhya Pradesh are low in soil available organic matter content, available nitrogen, available sulphur, low to medium in available phosphorus high in available potassium. Regarding available micronutrients, zinc, Manganese, copper and iron were deficient to sufficient in these soils. Soil organic carbon, available N, P, Zn, Mn, Cu, and Fe are important soil fertility constraints indicating their immediate attention for sustained crop production. The deficient micronutrient may be replenished to avoid the crops suffering from their deficiency and for optimum utilization of other nutrients. Integrated nutrient management holds the key for sustainable soil fertility management.
