Abstract

The soil physical properties are one of the components of soil fertility that function as a place for roots to penetrate. Different types of land uses affect the soil physical properties, especially on the availability of water and soil aeration which indirectly affects the availability of nutrients in the soil. Research on the soil physical properties of ex-gold mining, oil palm plantations and forests was carried out on Ultisol located in Tebing Tinggi Village, Dharmasraya Regency from April until October 2021. The objective of this study was to obtain the comparison of soil physics properties in ex-gold mining land with oil palm and forest land on Ultisol. The method on this study was a survey with purposive sampling on three different land uses (ex- gold mining land, oil palm land and forest) at a depth of 0-20 cm and 20-40 cm and it was replicated 3 times. The observed parameters were soil texture, organic matter, volume weight, soil pore space, soil water content, permeability, and soil aggregate stability. Based on soil analysis in the laboratory, it was obtained that the physical conditions of the soil in three different land uses, i.e the physical condition of the oil palm land and forest were better than the ex-gold mining land. The soil texture on ex-gold mining land was classified on sandy clay loam and sandy loam with a very low organic matter content (0,20-1,72 %) if compared with oil palm and forest land. The volume weight in each land use was relatively high with the total soil pore space was low except in oil palm land depths of 0-20 cm, which is 69,93 % vol (moderate). Permeability was slow to moderate with the soil aggregate stability classified as unstable to steady. Soil water content was relatively low except in forest land depths of 20-40 cm which very high criteria (33,93 %).

Abstract

Gold mining is an activity that utilizes natural resources by extracting the economic value of the deposits. Mining activities can produce hazardous pollutants, namely Hg (mercury), which can physically, biologically, or chemically damage soil quality. This study aimed to determine the role of biokanat application on the chemical properties of ex-mining land and to determine the effect of biokanat on reducing Hg levels in Kanagarian Padang Sibusuak, Sijunjung Regency. This study was a field experiment with 3 biokanat treatments (0, 10, and 20 ton/ha) with 3 replicates. The experimental 9 units were allocated based on Randomised Block Design. The data were statistically analyzed using an F-test with a 5% significance level. Then, it was continued using DNMRT if the Fcalculated > Ftable. The results showed that the dose of biokanat 20 ton/ha could increase the soil pH to 6.08, organic-C to 2.4%, P-available to 11.96 ppm, total-N to 0.23%, CEC to 2.58 cmol/kg, the basic cations especially Ca into 3.53 cmol/kg, Mg into 0.37 cmol/kg, K into 0.26 cmol/kg, and Na into 0.29 cmol/kg. Application of biokanat 20 ton/ha reduced the soil mercury (Hg) content to 15.96 ppm. Keywords: biocanat, mercury, gold mining

Abstract

Entisol merupakan tanah muda dengan tingkat kesuburan rendah akibat terbatasnya bahan organik dan unsur hara esensial seperti nitrogen (N) dan fosfor (P). Penelitian ini bertujuan membandingkan pengaruh penambahan biochar kulit kopi dan abu vulkanis terhadap beberapa sifat kimia Entisol, khususnya ketersediaan P dan N. Percobaan disusun menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan dan tiga ulangan: tanah tanpa perlakuan (K), tanah + abu vulkanis 5 t ha⁻¹ (A), dan tanah + biochar kulit kopi 5 t ha⁻¹ (B).  Hasil penelitian menunjukkan bahwa abu vulkanis meningkatkan pH tanah paling tinggi (hingga 7,4) dan memberikan peningkatan terbesar terhadap P-tersedia sebesar 0,39% (Olsen) dan 143,5% (Mehlich). Sebaliknya, biochar kulit kopi memberikan peningkatan lebih besar pada C-organik (11,63%), N-total (50%), dan KTK (13,60%) dibanding abu vulkanis yang masing-masing hanya naik 2,32% dan 6,36%. Penelitian ini menyimpulkan bahwa abu vulkanis lebih efektif meningkatkan pH dan P-tersedia, sedangkan biochar kulit kopi lebih unggul dalam memperbaiki C-organik, N-total, dan KTK tanah. Ameliorasi dengan biochar kulit kopi dan abu vulkanis dapat menjadi strategi efektif untuk memperbaiki kualitas dan kesuburan Entisol, meskipun efek kumulatifnya membutuhkan waktu serta tambahan sumber bahan organik lainnya untuk hasil yang lebih optimal. Penelitian lanjutan disarankan untuk mengeksplorasi dampak kumulatif dan jangka panjang dari perlakuan ini pada berbagai kondisi tanah dan iklim.

Abstract

Inceptisol is a marginal soil type with low fertility, limited water retention, and an acidic pH, which poses challenges for horticultural cultivation, including chaisim (Brassica rapa var. parachinensis). This study aimed to evaluate the effect of biochar dosage on soil physical properties, soil pH, and chaisim growth in Inceptisol from three locations: Singgalang, Padang Lua, and Sariak. Five biochar dosages were used (0, 15, 20, 25, and 30 tons/ ha-1). The observed parameters included water percolation, soil pH, and fresh plant weight. Results showed that the 20 tons/ha-1 dose gave the best results by reducing water percolation by up to 4%, increasing soil pH from 6.38 to 6.42, and producing the highest fresh plant weight of 203 grams per pot, which was much higher than the control (11 grams per pot). The increased soil pH improved the availability of nutrients such as phosphorus, calcium, and magnesium, which are important for plant growth. However, the 30 tons/ ha-1  biochar dose caused soil pore saturation, reducing aeration and nutrient uptake efficiency, resulting in a lower fresh plant weight of 97 grams per pot. Combining biochar with NPK fertilizer also improved water use efficiency and nutrient availability. The effectiveness of biochar was further influenced by initial soil characteristics, with the best results found in soil from Singgalang.This study showed that biochar could be a sustainable soil management strategy to improve horticultural crop productivity on marginal tropical soils.

Abstract

The physicochemical properties of soil play a crucial role in determining plant growth, development, and productivity. However, these properties are highly dynamic and can change due to management practices as well as natural phenomena such as volcanic eruptions. This study was aimed to analyze the physicochemical properties of soils under several land-use types (forest, coffee, chili, and rice fields) in Nagari Lasi following Marapi eruption on Dec 03, 2023. Undisturbed and disturbed soil samples were collected at depths of 0–30 cm and 30–60 cm. The results showed that, in general, there were no significant differences in either the physical or the chemical properties of soils across land-use types and soil depths. The soil texture in all land uses and depths was classified as sandy–silt loam, with a very low clay content (5–22%). The bulk density (BD) was <0.80 Mg m⁻³, total soil porosity (TSP) was moderate, and the hydraulic conductivity (HC) rate was high (20–31 cm h⁻¹), except in rice fields (5.34 cm h⁻¹). The plasticity index (PI) was low in both soil layers (2.21–5.31% at 0–30 cm and 5.63–7.21% at 30–60 cm). Soil chemical properties were also not significantly different among the land uses, particularly pH (5.12–5.86) and total N (0.13–0.41%) for both depths. However, the C/N ratio in the 0–30 cm layer tended to be lower than that in the 30–60 cm layer.

Abstract

Increasing the production of robusta coffee plants (Coffea canephora) can begin with selecting quality seeds. Improving seed quality can be done through fertilization using ameliorants and organic materials. Volcanic ash and goat manure are ameliorants and organic materials used in improving the planting medium. This study used a completely randomized design (CRD) with two factors: volcanic ash (25, 50, 75 g/polybag) and goat manure (15, 30, 45 g/polybag). The results of this study showed an interaction between volcanic ash and goat manure on the growth in height, shoot dry weight, and the root crown ratio of robusta coffee seedlings. The application of volcanic ash affects plant height, stem diameter, and the root crown ratio of robusta coffee seedlings. The application of goat manure affected plant height, leaf number, and the root-to-shoot ratio of Robusta coffee seedlings. The best ratio was 50 g volcanic ash per polybag and 45 g goat manure per polybag, which optimally increased the growth of Robusta coffee seedlings compared to other treatments. These results indicate that using volcanic ash with goat manure can be an effective alternative organic fertilizer to support coffee seedling growth and improve the fertility of the growing medium.
