The Green Revolution in India relied on high-yielding wheat and rice varieties that thrived with increased water and fertilizer use. Although fertilizers boost soil fertility, improper and unbalanced application by farmers has raised concerns about nutrient management. Many farmers overuse nitrogen and phosphorus, neglecting other essential nutrients like potassium, leading to nutrient depletion, reduced productivity, and lower fertilizer efficiency. Site-specific nutrient management (SSNM) addresses this issue by applying nutrients based on crop needs, optimizing fertilizer use, preventing nutrient loss, and promoting balanced fertilization for improved yields and soil health.
