Availability of N.P.K under low intensity of soil survey of Northern District of Madhya Pradesh (India)

This study investigates the soil macronutrient composition across various land use types (agricultural, forest, and riverside) in five northern districts of Madhya Pradesh, India (Shivpuri, Gwalior, Morena, Bhind, and Datia). A total of 30 soil samples were collected from both surface (0-15 cm) and subsurface (15-30 cm) depths to assess key soil parameters, including pH, Electrical Conductivity (EC), Organic Carbon (OC), Nitrogen (N), Phosphorus (P), and Potassium (K). The results revealed that the soil pH ranged from neutral to slightly alkaline across the districts, with the highest pH values observed in the Datia district. EC levels were found to be low to medium, with the highest values recorded in Shivpuri. Organic carbon content was generally low to medium, with Gwalior and Datia exhibiting higher organic carbon concentrations in forest and riverside areas. Nitrogen content varied from low to medium, with Datia exhibiting the highest nitrogen levels, particularly in forested areas. Phosphorus was found to be low to medium, with the highest concentrations in the Morena district under agricultural use. Potassium levels also showed variation, with the highest concentrations in Bhind district across all land use categories. This study provides a comprehensive assessment of the soil nutrient status in the region, contributing valuable insights for sustainable land management practices and soil fertility optimization.
