In Indonesia, Parkia speciosa (petai) is one of multy purpose tree species (MPTS). It belongs to the Fabaceae family and commonly found in agroforestry land in North Sumatera. This study aimed to map the distribution of land suitability for P. speciosa in Peria-ria Village and Sari Laba Jahe Village, Biru-biru Sub-district, Deli Serdang District, North Sumtera Province, Indonesia. This research was conducted by a survey method to collect soil samples based on the land unit yhat was obtained from overlay soil map, land use map, and slope map. Land suitability was evaluated based on the matching method. The Geographic Information System (GIS) was used to map the distribution of land suitability class. The results showed that the actual land suitability class for P. speciosa were moderately suitable (S2) (8.25%), marginally suitable (S3) (14.26%) and not suitable (N) (77.5%) in this area. Erosion hazard (eh) , root zone medium (rc), availability of water (wa), and nutrient retention (nr) were the dominant of limiting factor in this area. The most difficult constrain to counter were root zone medium and water availability.
