Abstract

Mining causes destructive soil properties, especially soil texture, water retention, and transmission. Applying biochar is the best way to improve soil physical properties. A glasshouse experiment was conducted to evaluate the role of biochar on soil physical properties based on a Completely Randomized Design (CRD) with four replicates. The research comprised six treatments (0, 4, 8, 12, 16, 20 t biochar ha-1). The results showed that the ex-gold-mined soil had coarse soil texture (sandy loam), high Bulk Density (BD) (1.43 g cm-3), low Total Soil Pores (TSP) (46.45%), low soil organic matter (SOM) content (1.27 %), very fast hydraulic conductivity (198.8 cm h-1). After biochar incubation, SOM increased (to 3.11%), soil BD decreased (to 1.16 g cm-3), TSP increased (to 54.17 %), water retention increased (at pF 1.0, 2.0, 2.54, and 4.2), plant available water (PAW) increased (into 8.33 %), and hydraulic conductivity decreased (into 24.70 cm h-1). However, applying 20 t biochar ha-1 still needs to bring the soil physical properties of the ex-gold-mined soil back into suitable soil for farming land.

Abstract

Cold lava floods contain volcano material that is rich in micronutrient which will gradually release through weathering process. The study of micronutrient elements affected by cold lava floods was conducted in Nagari Limo Kaum, Tanah Datar Regency, from October to March 2025. This research was aimed to assess and analyze the content of micronutrients (Fe, Mn, Cu, Zn, Mo and B) in land impacted by cold lava floods in Nagari Limo Kaum, Tanah Datar Regency. The study was carried out using a survey method. Soil samples were collected using purposive sampling from lava deposit (Locations 2, 3, and 4), areas affected by floodwater flow without deposition (Location 5), and unaffected areas (Location 1) as a comparison. Soil samples were collected from 0-20 cm soil depth at each location with 3 replicates. The analyzed parameters included soil pH, cation exchange capacity (CEC), exchangeable aluminum, and micronutrients (Fe, Mn, Cu, Zn, Mo and B). The results showed that increased the micronutrient content and exchangeable aluminium, increased while Zn and B content had low to very high criteria. The chemical properties especially pH and CEC of the soil  at L1 and L5, were lower that those at impacted soils.

Abstract

This study aims to identify the problems and develop rice agribusiness in Mentawai Islands from upstream to downstream and formulate appropriate policy recommendations to be implemented. The research location determined by purposive namely in the village Makalo and Malakopa District of South Pagai, Sikakap subdistrict Taikako Village, Village Saumanganya District of North Pagai, Bosua Village and Village Beriulou District of South Sipora, Village Rogdog and Madobag District of South Siberut. Respondents in this study were 30 farmers. Respondents farmers selected by simple random sampling method. The results showed that the majority of rice paddies new openings in six districts consist of peatlands with a depth varying from 0.4- > 2.0 meter, fields new openings that have been implemented in the Mentawai Islands in general can not be expected to result in maximum productivity due to problems of land suitability diverse. Farmers also do not take action appropriate technical culture starting from land preparation, seed selection, weeding, fertilizing and water management. Behaviorally agriculture, farmers in Mentawai Islands is not a society that blends with the culture of rice fields, it is because basically their agricultural base is dry land agriculture with farming patterns. This will certainly give a great challenge and not easy for the cultivation of rice in the Mentawai Islands.
