Mapping Soil Porosity: Unveiling India's Soil Dynamics with Remote Sensing

The physical state of the soil environment majorly defines plant growth.  The composition and properties of the soil matrix influence various transport processes and important flow between soil and plant. The porosity and density of soil help determine the water binding possibility, air movement, plant root penetration, etc. Just as the solid phase the geometry of the pore system is also complex. The porosity of the soil matrix is determined using densities- particle density and bulk density.  On the one side where we have several methods to determine porosity, we lack in the spatial details of it. Many attempts have been made to gather information about porosity through machine learning and remote sensing methods for specific locations. The present study attempts to map the porosity details over India using various databases and finally checking the accuracy and reliability of data sources.
