Research & Reports
Published findings, soil health benchmarks, and spectral data insights from RURSAT Research Labs — India's first NIR soil research laboratory.
A comprehensive NIR spectral baseline study of Vertisol (black cotton) soils across 14 districts in Maharashtra and Vidarbha. Covers organic carbon variability, micronutrient deficiency patterns, and moisture retention profiles across the 0–90cm depth range.
A validation study comparing RURSAT's NIR spectral predictions against reference wet chemistry lab results for 847 alluvial soil samples from the Indo-Gangetic Plain. Reports R² values, RMSE, and RPD ratios for 22 key parameters.
Spectral analysis of 1,200+ soil samples from Kharif crop zones across Telangana. Identifies spatial patterns of Zinc, Boron, and Iron deficiency and correlates them with reported yield losses in paddy and cotton.
Longitudinal spectral analysis tracking organic carbon decline in continuously irrigated soils across Punjab and Haryana. Identifies critical threshold zones and proposes spectral early-warning indicators for soil health degradation.
Developing a hyperspectral classification model for sand/silt/clay texture prediction to enable precision irrigation scheduling. Targeting sub-field spatial resolution for drip and sprinkler system optimization.
A pan-India spectral survey of Rabi crop soils across 9 states. Will establish the first nationally representative spectral soil health index for wheat, mustard, and chickpea growing regions.
