The main economic sector in Tubas is agriculture. There is a total of 150,000 dunams of arable land, of which 124,450 dunams are covered by forests and 10,604 dunams cultivated. Although the land is fertile, there is a lack of water for irrigation. The only spring used is in nearby Ein Far'a. Field crops account for 49% of the cultivable land, while fruit orchards account for 40% and vegetables make-up 11%. Israeli trenches around the neighboring villages of Ras al-Ahmar and Khirbet al-'Atuf prevent access to nearly 40% of Tubas' arable lands.
