Penelitian telah dilakukan di area lahan gambut Parit Demang, Kecamatan Pontianak Selatan, Provinsi Kalimantan Barat. Tujuan penelitian ini adalah untuk mengidentifikasi perubahan nilai resistivitas tanah sebelum dan sesudah pemupukan dan mengetahui pengaruh pemupukan pada nilai resistivitas tanah. Metode yang digunakan adalah metode geolistrik konfigurasi wenner-schlumberger. Pengambilan data mengaplikasikan 2 lintasan dengan panjang masing-masing 7 m. Dari hasil penelitian didapatkan nilai resistivitas tanah sebelum dan sesudah pemupukan adanya peningkatan yang terjadi pada Lintasan 1 dan Lintasan 2. Nilai resistivitas tanah Lintasan 1 sebelum pemupukan yaitu berkisar (0,374 "“ 270) Ωm, sesudah pemupukan berkisar menjadi (0,484 "“ 349) Ωm. Nilai resistivitas tanah Lintasan 2 sebelum pemupukan yaitu berkisar (0,374 "“ 269) Ωm, sesudah pemupukan yaitu berkisar menjadi (0,968 "“ 697) Ωm. Pengaruh pemupukan pada tanah berdasarkan nilai resistivitas terjadi peningkatan diduga karena pupuk kandang memiliki kemampuan menyerap air pada tanah, sehingga material tanah menjadi resistif.
Kata Kunci : Pupuk Kandang, Geolistrik Resistivitas, Resistif
