This study aims to determine the level of fertility and the suitability of various types of tropical fruit from open space at Universitas Pendidikan Ganesha campus area in Jineng Dalem, Singaraja. 18 soil samples with 3 depth categories (25, 50, and 75 cm) were collected, and the properties analyzed are limited to the the following parameters: soil texture, pH, base saturation, organic carbon (%), DHL (µs cm-1), cation exchange capacity (CEC), total nitrogen and available phosphorus and photassium. The characteristics data of the soil are used to determine their fertility status and suitability for tropical fruit plantations. The soil suitability assessment method was developed by the Indonesian Center for Research and Development of Land Resources, Agricultural Research and Development Agency, Ministry of Agriculture of the Republic of Indonesia. In addition, it was reported that the land boundary was mainly organic C content, N-total, P and available K. In addition to low fertility, this condition classifies the land suitability level in the category of marginal status for the 24 tropical fruit plants analyzed. The addition of compost is highly recommended to increase levels of C-organic in the soil. Subsequently, it is also recommended to apply manure to increase the N, available P, and K content of the soil. Availability of water sources or irrigation channels is also needed to maintain soil moisture.
Key words: Open space, tropical fruit plants, soil characteristics, land suitability.
