Understanding Micronutrients in Indian Soil
Discover how micronutrient deficiencies affect crop yields and learn the scientific approach to restoring vital soil health for better harvests.
Micronutrient deficiencies in Indian agricultural soils have grown significantly over recent decades due to intensive cropping patterns, unbalanced NPK fertilizer application, and depleted organic matter. Primary trace elements like Zinc (Zn), Iron (Fe), Manganese (Mn), and Boron (B) play crucial catalytic roles in enzyme activation, chlorophyll formation, and cell division.
When crops suffer from hidden hunger a state where yield loss occurs without visible foliar symptoms overall farm productivity drops by up to 25-40%. Soil testing conducted across Karnataka and South India indicates widespread Zinc deficiency in paddy and maize fields, while Boron deficiency severely impacts fruit set in crops like tomatoes, pomegranates, and bananas.
Key Recommended Solution:
- Apply chelated micronutrients during vegetative and flowering growth phases.
- Foliar sprays of 1-2 ml per litre ensure over 90% nutrient absorption efficiency.
- Combine with organic matter to prevent soil nutrient lockup and leaching.
