The agriculture is one of the most important aspects of the Indian economy. The productivity of agricultural lands is highly affected by the quality of the soil which is considered concerning its nutritional content. pH value and moisture content value are the two most important factors to determine soil fertility and irrigation need, respectively. In this paper, a novel design for a soil testing device has been proposed to measure the pH value and moisture content of the soil. The prototype has been developed which enables on-site testing. Experimental investigations for fabricated soil testing device were successfully carried out for dry and wet soil samples. With the proposed soil testing device, a pH value of 7.96 and 43.5% moisture content were obtained for the dry soil sample. Also, a pH value of 5.32 and moisture content of 64.1% was found in the wet soil sample. The obtained test results show that the proposed device is an affordable and portable solution for farmers to test the soil before the farming process.
