Ex coal mined soil generally had problem for farming activities, even though it had been re-vegetated for few years. This research was aimed to determine the effect of biochar derived from corn cob to improve the physical characteristics of ex coal mined soil and production of black corn. A pot trial was conducted in Glasshouse at Andalas University, Padang. Soil was taken from re-vegetated of ex coal mined soil in Sawah Lunto, West Sumatra, Indonesia. The soil was mixed with biochar at 4 different doses (0; 0.5; 1.0; and 1.5%) of the weight basis. The experimental units were allocated based on Completely Randomized Design. Parameters analyzed were soil texture, bulk density (BD), total soil pore (TSP), hydraulic conductivity (HC), soil organic matter (SOM), and plant available water (PAT), as well as corn production parameters. The result showed that biochar significantly increased the SOM. SOM content at 1.5% biochar application increased by 32.4% compared to the OM content of the soil without biochar (0 T ha−1). Improving SOM due to biochar application, improved the soil physical properties, especially it decreased the soil BD (r=-0.71); increased HC (r=0.65); TSP (r=0.71); PAW (r=0.86); aeration pore (r=0.54); field capacity (r=0.83); and decreased wilting point (r=-0.66). Biochar application also improved production of black corn. It linearly increased crop height (r=0.76); corn stalk dry weight (DW) (r=0.75); grain yield DW (r=0.75); shoot DW (r=0.74); and root DW (r=0.76). Biochar derived from corn cob could be used to improve physical properties of ex coal mined soil.

“…Another amendment material that is quite popular lately is biochar. Biochar could improve soil chemical properties (Yulnafatmawita et al 2020;Ethik et al 2021;Solfianti 2021), soil biological properties (Dermiyati et al, 2017;Nurbaity et al, 2019), and soil physical properties (Yulnafatmawita et al, 2021;Prakongkep et al, 2021;Gelardi et al, 2021;Fu et al, 2021).…”

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.

The physicochemical properties of Western Ethiopian soils were negatively threatened with continuous cultivation crop lands. Soil amendments with biochar and lime facilitate and improve soil physicochemical properties directly and indirectly and enhance crop productivity. A field experiment was conducted in Gimbi District, Western Ethiopia, to examine the effects of combined coffee husk biochar (CHB) and soil test value-based lime (STV) rate application on physicochemical properties of acid soils. The trial included eight treatments, including control, 100% STV, 10 ton of CHB, and CHB + STV rates at 10 ton + 75%, 10 ton + 50%, 7.5 ton + 75%, 7.5 ton + 50%, and 5 ton + 75% ha−1on two farm fields. The fields were laid out in RCBD with three replications. The treatments had substantial effects on P<0.05) on the soil’s physicochemical characteristics. The application of biochar and lime in Farms-1 and 2 reduced soil BD from 1.21 and 1.41 g·cm−3 to 1.15 and 1.12 to 0.90 and 0.97 g·cm−3, respectively. The soil pH level was increased from 5.10 to a range of 5.58 to 6.11 in Farm-1, and in Farm-2, from 4.64 to a range of 4.64 to 6.22 levels. The application of 10 ton of CHB + 75% of STV in Farms-1 and 2 resulted in the highest SOC of 7.44% and 7.68%, respectively. The application of 10 ton of CHB + 75% of STV in Farms-1 and 2 resulted in 4.86 mg·kg−1 and 6.96 mg·kg−1 available P, respectively. Available P was positively correlated with pH (0.62), SOC (0.63), and CEC (0.66). Exchangeable acidity was decreased from 4.64 cmol(+)kg−1 to a range from 3.19 to 0.98 cmol(+)kg−1 in Farm-1 and from 5.00 cmol(+)kg−1 to a range from 3.38 to 1.10 cmol(+)kg−1 in Farm-2. Therefore, amending the strongly acidic to very strongly acidic soil with a combined CHB (7.5 to 10 ton ha−1) and STV (50 to 75% ha−1) rates had improved the soil physicochemical properties of agricultural lands. To make a firm conclusion, research on soil analysis after crop harvest and economic benefit is required.
