Land suitability evaluation of abandoned tin-mining areas for agricultural development in Bangka Island, Indonesia

Abstract

: Kepulauan Bangka Belitung, Indonesia is one of the tin mineral-producer in the world.Agricultural crops could be a wise option for the reclamation since abandoned tin-mining lands have a high potency to be used as agricultural lands. This study was aimed to evaluate of the land/soil characteristics of abandoned tin-mining areas and to establish land suitability of the land area for agriculture used to formulate appropriate land development measures and amelioration strategies forutilization of mined areas for crop production. The land evaluation was conducted by comparing the land characteristics in every type of abandoned tin-mining areas with its crop requirements. The current suitability showed that in general food crops, vegetable crops, fruit crops, and industrial crops were consider as not suitable (N). Spice and medicinal crops [pepper (Piper nigrum L.)] and citronella (Andropogoh nardus L. Rendle)] were consider as not suitable (N), while the Jatropha (Jatropha curcas L.) and Kemiri Sunan (Aleurites moluccana L. Willd) crops were considered as marginally suitable (S3) in abandoned tin-mining areas. The forest crops and forage crops were considered as marginally suitable (S3). The water availability, soil texture, and low soil fertility were considered as the limiting factors of all crops to get optimum production. For agricultural development, the soil physical and chemical properties of abandoned tin-mining land must be improved through integrated farming.

Soil Quality Index for the Two Agricultural Areas along the Naboc River in Davao de Oro, Philippines Contaminated with Mercury

“…Potassium concentration in soil is highly abundant, but available fractions were usually low et al 2003), which adversely affected agricultural crops yield. In Diwata, on the other hand, the mine tailings that were tilled in the agricultural plantations sampled caused soil aggregates to become looser -affecting the water holding capacity, bulk density, and nutrient retention and availability (Asmarhansyah et al 2017;Sencindiver and Ammons 2000).…”

Resource ecologies, political economies and the ethics of audio technologies in the Anthropocene

“…The short-term profits from tin mining lead to long-term problems concerning potential use of post-mining sites. The removal of overburden (the layer above the desired ore, in this case, topsoil) and toxic runoff from water and air interacting with mine tailings (the 99.985% of the gravel and rock that is stirred up that does not contain sufficient tin) has rendered much of the land of Bangka incapable of efficiently growing agricultural crops (Asmarhansyah et al 2017), similar to the role tin mining had on topsoil degradation in Nigeria (Godoy 1985). Sometimes pepper plantations were directly converted to ‘tin plantations’ (Erman 2007, p. 199).…”

The Amelioration of Post Tin Mining Sand Tailing Medium with Chicken Manure for Pepper Cultivation

“…One of the impacts of tin mining activity is the formation of tailings land. The tin mine tailings land has a low soil fertility status, indicated by the dominance of the sand fraction and low soil pH, organic carbon, cation exchange capacity, and essential macronutrients (Asmarhansyah et al, 2017).…”
