Sufficient knowledge of land’s features helps people in various ways, such as economy, preference, at the planning stage to form a good plan.

According to results obtained, most of the lands of Tokat Province is not suitable for agriculture in general. Only 34% of Tokat Province’s lands is in range of slope interval (0-12 %) which is suitable for agriculture.
