Q1. Discuss emerging applications of geoinformatics in soil related studies.
- Digital Soil Mapping (DSM) predicts soil properties using RS, GIS, and machine learning from environmental covariates.
- Precision Agriculture uses geoinformatics for variable rate application of inputs based on soil maps, optimizing resources.
- Soil Erosion Monitoring identifies hotspots and predicts soil loss using time-series RS and GIS-based erosion models (e.g., USLE).
- Soil Moisture Estimation employs microwave, thermal infrared, and SAR remote sensing for irrigation and drought management.
Answer: Geoinformatics, encompassing Geographic Information Systems (GIS), Remote Sensing (RS), and Global Positioning Systems (GPS), offers transformative capabilities for detailed and dynamic soil-related studies. These technologies move beyond traditional, laborious field-based surveys to provide efficient, comprehensive, and spatially explicit insights into soil properties and processes. One of the most significant emerging applications is Digital Soil Mapping (DSM). DSM utilizes statistical and ma...
