Integrated Nutrient Management (INM)
Modern agriculture has achieved remarkable growth through fertilizers, but this success has come at a cost. Overdependence on chemical fertilizers has gradually weakened soil health, reduced organic matter, and disturbed the natural balance that supports plant growth. To bring back that balance, a scientific yet sustainable approach is essential — and that approach is Integrated Nutrient Management (INM).
What is INM
Integrated Nutrient Management is the process of combining chemical fertilizers, organic manures, and biological sources in a balanced way to maintain soil fertility and achieve sustainable crop productivity. It doesn’t reject fertilizers — it refines their use. INM ensures that every nutrient added to the soil works efficiently and harmoniously with natural soil processes.
How INM Works
INM brings together three powerful sources of nutrition:
-
Organic matter like compost, green manure, and farmyard manure — which improve soil texture, moisture, and microbial activity.
-
Chemical fertilizers — which provide immediate nutrient supply for better yield.
-
Biofertilizers — beneficial microbes that help plants absorb nutrients more effectively and improve root health.
By combining these, farmers can reduce fertilizer costs, improve soil health, and enhance productivity in the long term.
Benefits of INM
-
Restores and maintains soil fertility.
-
Reduces nutrient losses and environmental pollution.
-
Improves nutrient-use efficiency.
-
Builds resilience against drought and stress.
-
Ensures better crop quality and yield stability.
