Urban Farm DB summary
A 2025 study analyzed and compared the physical characteristics of soil in two areas of Samarinda City, Indonesia — Samarinda Ulu and Samarinda Utara sub-districts — as a basis for evaluating urban farming potential, using a descriptive-comparative approach to examine soil texture, structure, color and consistency. Results showed the soil in Samarinda Ulu had a fine sandy loam texture, small crumb structure and olive brown color (2.5Y 4/4), while soil in Samarinda Utara had a somewhat coarser texture, angular blocky structure and reddish brown color (5YR 4/4). These differences indicate variation in water retention and drainage capacity that affects crop suitability: Samarinda Ulu soil was found more suitable for horticultural crops, while Samarinda Utara soil suited drought-tolerant plants. The study is intended to inform the development of sustainable urban agriculture in humid tropical regions.
