Question: What is regur soil? State its distribution and agricultural significance in Rajasthan.
Model Answer:
Regur (also called black cotton soil) is a dark grey montmorillonite clay soil derived from Deccan basalt. In Rajasthan, it is found in Kota, Bundi, Baran, and Jhalawar (Hadoti region). Key properties: swells when wet, cracks when dry, high moisture retention. Supports Rajasthan's soybean, cotton, and chickpea cultivation.

Question: Where was the Soil Health Card Scheme launched and what information does a Soil Health Card provide?
Model Answer:
The Soil Health Card Scheme was launched on 19 February 2015 at Suratgarh, Rajasthan by PM Narendra Modi. Each card reports 12 soil parameters — pH, EC, organic carbon, nitrogen, phosphorus, potassium, sulphur, and 5 micro-nutrients (Zn, B, Fe, Mn, Cu) — with farm-specific fertilizer recommendations. Rajasthan issued 72.66 lakh cards (Cycles 1+2).

Question: Discuss the major soil degradation problems of Rajasthan and the conservation measures adopted to address them.
Model Answer:
Introduction: Rajasthan, covering 10.4% of India's land area, faces severe soil degradation from both natural and anthropogenic causes.
Key Points:
Wind erosion dominates western Rajasthan — Jaisalmer, Barmer, Bikaner — removing 60–100 tonnes topsoil/ha/year; Rajasthan accounts for ~59% of India's wind-eroded land. CAZRI's shelter belts and sand dune stabilization programmes reduce soil loss by 40–60%.
Waterlogging and secondary salinization in IGNP command area — ~1.54 lakh ha waterlogged in Sri Ganganagar and Hanumangarh — result from uncontrolled canal irrigation without sub-surface drainage. Remedied by drainage tiles and canal lining.
Ravine/gully erosion by Chambal tributaries has degraded ~3.78 lakh ha in Kota-Sawai Madhopur belt; check dams, gully plugging, and vegetation of ravine sides are employed.
Government response: Soil Health Card Scheme (launched Suratgarh, 2015) has issued 72.66 lakh cards; 27 soil testing labs provide farm-specific nutrient data; NMSA and IWMP fund watershed treatment across 50+ lakh ha.
Conclusion: Rajasthan's soil conservation requires integrated approaches combining mechanical engineering, biological measures, and farmer-centric health monitoring to sustain agricultural productivity under climatic stress.
