I have three different data-sets, including soil properties (salt content, pH and EC1:5), Landsat derived indices (salinity index, NDVI and brightness index) and EM38 data (apparent electrical conductivity of the soil profiles with the depth of 0.75 and 1.5 meters) from my study area. And I would like to develop a model to quantify the soil salinity information using these parameters, especially these obtained by the sensors (Landsat and EM38). Thanks in advance!
Hi Ahmatjan, Thanks for the papers and the contact information!
All the best,
You can use Microwave based satellite data along with field data for developing a model in any GIS sofware.
Dear Hayder, Dear Prafull,
Thanks for the suggestions! Yes, one of my colleague is using RADARSAT SAR data to quantify soil salt content in our research area. In my case, I wanna develop a model using Landsat and EM38 data, because the multi-spectral bands of Landsat could effectively characterize the surface including soil and vegetation, and EM38 can timely depict the soil profile. more important thing is, Landsat data is freely available and EM38 is widely accepted and used in agricultural soil surveys. So, if we could establish a suitable model, then we could largely reduce the regional soil quality assessment workload.
All the best!
