Describe the main characteristics of soils of Madhya Pradesh.

Main Characteristics of Soils in Madhya Pradesh:

Madhya Pradesh exhibits five major soil categories governed by underlying geology and weathering:

• 1. Black Soil (Regur - ~47% of MP - Largest Share):
  • Formed by weathering of Cretaceous Deccan Trap basalt; rich in iron, lime, calcium, and alumina; deficient in nitrogen, phosphorus, and organic matter.
  • High clay content ($>40$) imparting extraordinary moisture retentivity and self-ploughing cracks upon drying; ideal for Soybean, Cotton, and Wheat (Malwa, Nimar, Narmada Valley).
• 2. Red and Yellow Soil (~36.5% - Second Largest):
  • Derived from Archean crystalline granites/gneisses in Baghelkhand (Rewa, Sidhi, Singrauli); red colour due to ferric oxide; sandy-loamy texture ideal for Paddy (Rice) cultivation.
• 3. Alluvial Soil (जलोढ़ मृदा - ~3%):
  • Deposited by Chambal and its tributaries in Chambal-Gwalior plains (Bhind, Morena, Sheopur); highly fertile neutral soil ideal for Mustard and Wheat; highly prone to gully ravine erosion.
• 4. Mixed Soil & Laterite Soil: Bundelkhand (mixed red-black) and Balaghat/Chhindwara (leached acidic laterite soil).
