- •
The spatial variability of soil micronutrients in the Trans-Gangetic Plains of India was assessed.
- •
The nugget/sill ratio values were 0.60, 0.37, 0.34 and 0.19 for available Zn, Fe, Cu, and Mn, respectively.
- •
Semivariogram range values of Fe, Cu, Zn and Mn were 140, 61, 32 and 5 km, respectively.
- •
The distribution maps generated could be used as a guide for precise and site-specific micronutrient management in the study region.
