The Bannu lowland is made of sandy and gravelly materials brought down by rivers, except for a small area near Bannu town, which contains rich silt. Perennial irrigation, made possible by the construction of the Kurram Garhi Dam on River Tochi, is confined to the land between River Kurram and River Tochi.
Bannu plain produces wheat, gram, maize, barely, rice and sugarcane. In unirrigated parts of Kohat and Bannu plains are raised flat tailed sheep, camels and donkeys and wool is the most important commercial product.
