Reclaimed Nickel Mine Land: Characteristics, Potential, Challenges, and Management
Reclaimed nickel mine lands often exhibit degraded soil properties, including reduced fertility and altered physical and chemical characteristics.
A study focusing on a post-mining area in Pomalaa, Southeast Sulawesi, identified that poor tree growth in revegetated areas was linked to deficiencies in essential nutrients such as calcium (Ca), iron (Fe), copper (Cu), and manganese (Mn). Additionally, the study highlighted a high rate of erosion in these areas, further complicating reclamation efforts.
Land use conflict on agricultural dryland: an analysis using GIS and land capability evaluation specific for humid tropics.
This research utilized GIS to assess land capability and identify conflicts between existing land use and regional spatial planning regulations.
The findings revealed significant discrepancies, with approximately 39.9% of the area experiencing land-use conflicts, primarily due to the conversion between dryland farming and non-agricultural uses. Factors such as decreased soil fertility leading to lower incomes were identified as crucial in driving these changes.
A Proposed land suitability requirements for maize: specific in the humid tropic of Indonesia,
This research aimed to modify land suitability criteria for maize in Indonesia's humid tropics, focusing on three representative districts in South Sulawesi:
Jeneponto, East Luwu, and Bulukumba.
The study identified key land characteristics significantly affecting maize yield, including precipitation during the growth cycle, soil pH, organic carbon content, and base saturation. Optimal conditions for maize were determined to be a precipitation range of 650-900 mm during the growth cycle, soil pH between 6.8 and 7.0, organic carbon content above 2.2%, and base saturation over 62%. These findings provide valuable insights for land suitability assessments and maize cultivation in Indonesia’s humid tropical regions.
