<![CDATA[The market demand for Cilembu sweet potato is increasing from year to year. Therefore it is necessary to develop Cilembu sweet potato land in other areas to solve this problem, including non-typical Cilembu sweet potato land. Investigations on the distribution of fertile soils are carried out on non-typical agricultural lands so that farmers can assess fertility problems in the soil, which can increase crop productivity. This specialty uses a high-precision agricultural approach to developing geophysical technology, one of which is Electrical Resistivity Tomography (ERT). This research was conducted to determine the characteristics of non-typical Cilembu sweet potato agricultural land in the Cicalengka sub-district. The results show that the resistivity values range from 10 to 800 Ωm, indicating that this area results from weathering of sedimentary rocks. The study results stated that the Cilembu variety of sweet potatoes could be developed on non-typical land in this area by considering the inhibiting factors. Knowing these inhibiting factors is expected to determine the steps in land management as a solution so that non-typical areas can help market demand for the availability of Cilembu sweet potato varieties.]]>
