Identification of Electrical Conductivity of The Volcanic Soil on Fertilizer-Exposed Agricultural Field (Case Study on Agricultural Field Parompong, West Java)

Abstract

Parongpong volcanic soil is a type of Andosols soil used for short-lived crop farming. Increased agricultural production is usually by giving excessive fertilizer that causes contamination of farmland and leaves residue residues that contaminate the soil. The research has been done using geophysical methods to determine the soil electrical properties of the Huma EC technology, which results in resistivity value and converts it into conductivity. Data collection on agricultural and non-agricultural land was measured as a comparison. The result shows that agricultural land’s conductivity value is higher than non-agricultural land. The range of conductivity values in non agricultural land is 1.44 - 15.11 mmhos/cm. The content of conductivity values in non-non-agricultural land is 0.72 - 2.7 mmhos/cm. The value can be used as a Parongpong volcanic agricultural area conductivity database.
