1. Spectral Response of Pulse Crops to Soil Acidity for Soil pH Mapping

In this work, we explore the observable differences in the spectral reflectance of pulse crops in acidified and non-acidified soil regions of multiple Montana fields. Satellite observations are collected throughout the growing season using Landsat 8 & 9 and Sentinel 2 A & B. The variations of crop reflectance in acidified (pH < 5) and non-acidified (pH 6.0 to 7.0) are analyzed and used to support why both multi-temporal regression and machine learning models are... P.
