India's Green Revolution is hailed as a landmark achievement in modern agriculture, transforming the nation from a food-deficit importer into one of the world's largest food grain producers. High-yielding crop varieties, expanded irrigation networks, and widespread adoption of chemical fertilisers played pivotal roles, according to Harsh Vardhan Bhagchandka in The Hindu BusinessLine. Yet, more than half a century later, the most important lesson is not that agricultural inputs can boost productivity, but that "quality, stewardship and balanced use determine whether those gains remain sustainable over generations." As India stands on the threshold of a Bio Revolution powered by biofertilisers, microbial consortia, biostimulants and other biological inputs, this lesson has never been more relevant.
The Green Revolution's Legacy
The Green Revolution's success was undeniable, but over time, rapid fertiliser use expansion outpaced balanced nutrient management. India's fertiliser consumption grew from approximately 2.3 million tonnes in the late 1960s to more than 65 million tonnes in 2023-24, according to the article. Heavy subsidies on nitrogen-based fertilisers, especially urea, led to severe soil nutrient imbalances and a huge fiscal subsidy burden. Nutrient application became skewed towards nitrogen at the expense of phosphorus, potassium, and micronutrients. The consequence unfolded over decades: declining nutrient-use efficiency, deteriorating soil health, and increasing pressure on agricultural ecosystems. The issue was not the fertilisers themselves but the absence of guardrails to ensure balanced and efficient use at scale.
| Period | Fertiliser Consumption (million tonnes) | Key Driver |
|---|---|---|
| Late 1960s | ~2.3 | Initial Green Revolution adoption |
| 2023-24 | >65 | Subsidised nitrogen fertilisers |
In response, initiatives such as the Soil Health Card programme distributed more than 25 crore cards based on over 8 crore soil samples, providing farmers with field-specific nutrient recommendations. The programme reflects a broader recognition that productivity and sustainability must advance together.
The Bio Revolution: Promise and Pitfalls
Today, biological inputs are emerging as promising tools for sustainable agriculture. By improving nutrient availability, enhancing soil microbial activity, and supporting crop resilience, they can complement conventional fertilisers while reducing environmental footprint. The enthusiasm surrounding biologicals is well-founded, but long-term success depends on something more fundamental: trust. For farmers, every input purchase is an investment made months before harvest—uncertainty is unacceptable. Trust, therefore, becomes the most valuable currency in agriculture.
Building Trust Through Quality Assurance
When the Fertilizer (Control) Order was extended to include biostimulants, regulators faced a marketplace already containing tens of thousands of products, the article notes. The objective was not to slow innovation but to establish common standards that distinguish proven technologies from unverified claims. The lesson: quality assurance is most effective when it evolves alongside a category, not after problems emerge. For biological inputs, this means robust efficacy validation, clearly defined microbial specifications, shelf-life standards, traceability mechanisms, and accessible testing.
Implications for Agricultural Commodity Markets
For commodity traders and agribusinesses monitoring India's agricultural policy shifts, the trajectory of the Bio Revolution will influence input demand patterns. If past imbalances are repeated, risks of soil degradation and declining yields could affect long-term crop output forecasts. Conversely, successful adoption of quality-assured biologicals may reduce dependence on synthetic fertilisers, altering procurement strategies for urea and other nutrients. The article underscores that policymakers and industry must collaborate now to build a framework that ensures sustainability—avoiding the costly corrections that followed the Green Revolution.
