Agricultural productivity is strongly correlated with the physical characteristics of the soil. Generally, the characterization of agricultural land is carried out in traditional way, but this study presents the results of microtremor measurements to obtain information about the structure of shallow soil layers in Cilembu sweet potato farmland using HVSR method. Measurements are carried out at 12 points on an area of 40×50m. The HVSR method is used to determine the frequency and amplification values at each point. The results show that the frequency values for more fertile area are 9 – 14 Hz, and the amplification values from 2,5 – 4. The shear wave velocity from the inversion of the HVSR curve is 70 – 400 m/s from a depth of 0 –40m. Based on the Vs classification table, the soil used in agriculture in the study area is included in the soft to medium soil type with a range of 70 – 208 m/s.
