Bihar’s soil health is foundational to the state’s agricultural productivity, rural livelihoods, and food security. However, the state faces significant challenges with soil degradation, nutrient depletion, salinisation, and erosion, exacerbated by intensive farming practices and climate variability.

Challenges in Bihar’s Soil Health

Recent data highlights that over 7.5 lakh hectares of land in Bihar are degraded due to factors such as water erosion, salinisation, and vegetation depletion. Districts like Samastipur, Muzaffarpur, Siwan, and Champaran exhibit high levels of salt-affected soils, which significantly reduce crop productivity and soil biodiversity. Overuse of chemical fertilisers, stubble burning, and incorrect irrigation practices further compound soil health problems, posing a threat to the sustainability of agriculture in Bihar [Times of India, 2024].​

Government Initiatives: Soil Health Card Scheme

To combat soil degradation, the Government of India, in partnership with Bihar’s Department of Agriculture, implemented the Soil Health Card (SHC) Scheme starting in 2015. The scheme aims to provide farmers with soil-specific fertiliser recommendations based on detailed soil testing results, promoting balanced and sustainable nutrient use. In Bihar, over 28 lakh soil health cards have been distributed, covering 38 districts, with soil samples collected and tested at state-operated laboratories. This enables tailored nutrient management and integrated practices to restore soil fertility [Agro-Economic Research Centre, Bhagalpur].​

Impact of Soil Health Card Scheme

Research by the Agro-Economic Research Centre for Bihar and Jharkhand demonstrated measurable improvements due to the SHC Scheme, with crop yields increasing modestly—1.98% for paddy, 0.84% for wheat, and 2.23% for lentil. The scheme also raised awareness among farmers about balanced fertilisation and organic amendments. However, issues like delays in report delivery, technical jargon in soil health cards, and limited farmer training in interpreting recommendations restrict full potential benefits. Policy suggestions include printing reports in Hindi with local land measurement units, enhancing laboratory infrastructure, and better farmer outreach [Agro-Economic Research Centre, Bhagalpur].​

Ongoing Challenges and Recommendations

• Expanding soil testing coverage and timely availability of results.
• Increasing farmer education on integrated nutrient management and organic practices.
• Developing localised soil management strategies using digital tools and precision agriculture approaches.
• Encouraging policies to reduce excessive chemical fertiliser use and promote organic farming.
