Abstract
Soil pH is one of the most important soil properties influencing plant growth and productivity. The
pH of the soil affects nutrient availability, microbial activity, and soil structure. As a result, accurate
soil pH measurement is critical for effective soil management, plant growth, and sustainable
agriculture practices. This study was conducted by analyzing the Landsat 8 satellite images, soil
data of field surveys, laboratory analyses and statistical computations. The research combined and
integrated the soil data from survey and laboratory with Landsat 8 satellite images to build two
multiple regression equations model to enable the comparison of the two datasets i.e., field data
and satellite data. The field and satellite data depicted the soil pH to range between 6.4 -7.8 for...
