Soil Nutrient mMapping
Get the latest Soil Nutrient Mapping news, research and developments covering digital soil assessment, nutrient variability, remote sensing, spectroscopy, GIS and machine learning for precision agriculture. Coverage includes mapping of nitrogen, phosphorus, potassium and micronutrients to support better soil fertility assessment and site-specific fertilizer management.
Modern approaches combine laboratory soil samples with satellite imagery, UAV sensors, hyperspectral data, proximal sensing and environmental information to estimate nutrient concentrations across fields and larger agricultural regions. Recent research using Sentinel-2 imagery and machine learning has demonstrated the potential to map available phosphorus and exchangeable potassium, while UAV-based models are being developed for high-resolution nutrient assessment.
Find updates on nutrient maps, soil spectroscopy, digital soil mapping, sensor technologies, variable-rate fertilization and decision-support systems. Research from India’s Bundelkhand region has also combined diffuse reflectance spectroscopy with digital soil mapping to generate nutrient recommendations across smallholder farms, while emerging work is integrating hyperspectral imaging and advanced machine learning for faster, non-destructive soil assessment.
