Abstract: The study on land characteristics of coffee cultivation at 28 locations in Chiang Mai, Chiang Rai and Tak was carried out during April to October 1984. Emphasis was put on both physical and chemical soil properties as well as major constraints limiting to coffee cultivation. General fertility status and potential of land for coffee production were evaluated by using some soil properties and site characteristics. It was found that highland soils in the investigated area are more or less similar in general characteristics. Most of them are reddish brown to dark brown Lateritic Soils developed on moderate to high slopes. These soils are some what similar to the Great Group Palehumults in 1975 USDA soil classification system. Most of the soils under investigations have a medium fertility status. The potential for coffee cultivation of highland soils are moderate. Due to its topography, slope is the major limitations for coffee production. With conservation techniques, coffee could be established successfully slope lower than 50%.
