Abstract

Indonesia is known as the second largest tin producer in the world. Areas abandoned after tin-mining activities are degraded lands and low soil fertility status. This study aimed to assess the potential of abandoned tin-mining areas for agricultural development in Bangka Island, Indonesia. For agricultural use, the soil physical and chemical properties of abandoned tin-mining areas must be improved through integrated farming systems. The field experiment results showed application of organic and inorganic amendments improved the soil properties and gave better growth, grain yield, and yield components of corn. Based on potential suitability, integrated farming systems in abandoned tin-mining arcas is divided into three types: Type A is a group of 1) sand tailing, 2) sand tailing with vegetation, and 3) mixture of sand tailing and overburden; Type B is a mixture of sand tailing and overburden with vegetation; and Type C is a group of 1) sand tailing from unconventional mining and 2) overburden from unconventional mining. Type A is marginally suitable for spice and medicinal, forestry, and forage crops. Type B is highly suitable for acacia; moderately suitable for citrus, pepper, kemiri sunan, sengon, and mahogany; and marginally suitable for food crops, vegetable, fruit, industrial, spice and medicinal, and forage crops. Type C is moderately suitable for sengon and acacia and marginally suitable for spice and medicinal crops, forest crop (mahogany), and forage crops. The measures recommended for the utilization of abandoned tin-mining areas for agricultural use are: 1) levelling-off the abandoned tin- mining areas, 2) applying enriched top soil, especially for parrenial crops, 3) applying organic and inorganic amendments, and 4) applying water from pond and mulching from crop residues. To ensure agricultural development in abandoned tin-mining areas, the involvement of national and local governments, tin-companies, and investors are needed.
