Abstract

Soil horizon development is a determinant of soil type and characteristics. The morphology reflects the stages of soil formation by observing the genetic horizon. The genetic horizon is a soil layer distinguished by symbols (O, A, E, B, C, and R). Soil formation can also be obtained from the silt-clay fraction as part of the soil texture observation. The silt-clay ratio can reflect the soil morphology and genesis. This study aimed to determine the silt-clay ratio as an indicator of soil development and fertility. This study was conducted in 2020 in Manismata Sub-District West Kalimantan Province with soil parent material derived from sedimentary rocks with the topography of 0-3%, 3-8%, and 8-15%. The observations were carried out on five soil profiles in terms of morphology, texture, organic matter, nitrogen, CEC, and Ca. Based on the results, entisol (regosol) had A-C genetic horizon and silt-clay ratio >2.73. Meanwhile, inceptisol (kambisol) had an A-B-C genetic horizon and a silt-clay ratio of 1.44 – 2.24. The silt-clay ratio in entisol had a significant influence on organic matter, CEC, and Ca of 75.79%, 86.98%, and 85.14%, respectively. Silt-clay ratio in inceptisol had a significant influence on organic matter, CEC, and Nitrogen. 3-8% inceptisol had a negative relationship of 67.25%, 52.33% and 84.59%, respectively. Meanwhile, 8-15% of Kambisol had a positive relationship with R2 of 69.08%, 54.49%, and 66.61%, respectively. The difference in the relationship (negative, positive) on inceptisol was due to 3-8% inceptisols having lithologic discontinuities. Thus, it can be concluded that the silt-clay ratio can be an indicator of soil development and fertility.Key words : Fertility, Morphogenesis, Silt/Clay, Soil Weathering

Abstract

Today, peatland fires cause peat soil changes and release carbon emissions. The area protected as a peat conservation area in 2019 was not spared from fire incidents, where the land is an area with a maintained groundwater level and has monitoring data on groundwater level and peat thickness. This paper aimed to identify the subsidence, carbon emissions, and several physical properties of peat soil in burned and unburned peat conservation areas. The variables measured were hydraulic conductivity, subsidence, bulk density, water content, carbon content, and carbon emissions. The number of observation plots was 6 plots, with three (3) unburned plots and three (3) burned plots located in the Peat Conservation Area in Ketapang Regency, West Kalimantan. The six observation plots were in peatlands with the Typic Haplohemists subgroup, and shrub land cover. The results showed that the hydraulic conductivity and carbon content in unburned and burned land were not statistically and significantly different (P>0.05). The values of bulk density, water content, subsidence, and carbon emissions on burned land were significantly different (P<0.05) compared to unburned land. Subsidence in unburned locations was 1.83 ± 0.44 cm, while in burned areas it was 5.56 ± 0.84 cm. The amount of subsidence affects the amount of carbon emissions resulting from the loss of peat layers, namely on unburned land it was 9.24 ±3.13 tonnes/ha, and 35.53±3.73 tonnes/ha on burned land. The results of carbon emissions from subsidence caused by land fires can be determined as a basic emission factor for these two land conditions with similar peat characteristics. Keywords : Peat Fires, Peat Conservation Areas, Physical Properties of Peat, Subsidence, Carbon Emissions

Abstract

The utilization of land that is not aligned with its environmental carrying capacity is a significant issue in Indonesia. One affected sector is oil palm plantations, which covered an area of 16.38 million hectares in 2019. However, the government policy through Presidential Instruction Number 8 of 2018 halted this expansion. This policy also applies to independent farmers who must adhere to the principles and criteria of the RSPO (Roundtable on Sustainable Palm Oil), including practices to maintain soil fertility, control erosion and soil degradation, and plan development locations based on soil surveys. This study aims to evaluate the land capability of independent oil palm plantations in Sintang Regency. The methods used include soil surveys and land evaluation with the collection of soil morphology data and soil type classification. The study results show significant differences between the soil type map data issued by BBSDLP in 2010 and field verification results. Land evaluation identified four different soil units, each requiring specific management based on limiting factors such as plant root penetration, water excess, soil texture, slope gradient, and waterlogging. Proper land management includes soil and water conservation techniques, cover cropping, liming, and good drainage. Water management on peatlands must also consider environmental aspects to prevent ecosystem damage. With proper evaluation and management, land productivity can be sustainably increased.

Abstract

Tanah Ultisol memiliki potensi besar untuk pertanian, namun karakteristiknya yang kurang subur membatasi produktivitas tanpa pengelolaan yang tepat. Biochar mampu meningkatkan kandungan karbon tanah, retensi air, dan efisiensi hara, sementara pupuk kandang ayam memperbaiki kesuburan tanah dengan menyediakan hara makro dan mikro, meningkatkan KTK, serta mengurangi toksisitas logam berat seperti aluminium, besi, dan mangan. Penelitian ini bertujuan untuk mengetahui interaksi antara biochar tankos dan pupuk kandang ayam terhadap ketersediaan hara N, P, K dan pertumbuhan tanaman jagung di tanah Ultisol. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 9 perlakuan dan 3 ulangan, sehingga terdapat 27 polybag. Hasil penelitian menunjukkan bahwa biochar tankos meningkatkan diameter batang jagung sebesar 14,53%. Pupuk kandang ayam meningkatkan pH tanah (6,12%), K-dd (7,87%), dan P-tersedia (119,45%). Kombinasi 900 g biochar tankos dan 900 g pupuk kandang ayam (B3C3) secara signifikan meningkatkan N-total, tinggi tanaman (119,45%), dan diameter batang (23,53%). C-organik tidak menunjukkan pengaruh nyata. Hasil ini menunjukkan bahwa interaksi biochar tankos dan pupuk kandang ayam efektif meningkatkan kesuburan Ultisol dan pertumbuhan jagung.

Abstract

Former gold mining land, especially those abandoned without reclamation, experiences serious physical, chemical, and biological degradation, and is potentially contaminated with heavy metals such as mercury (Hg). This study aims to evaluate the effectiveness of organic farming-based bioreclamation and good soil management, using dwarf elephant grass (Pennisetum purpureum) and chicken manure in improving the condition of former gold mining land. The parameters analyzed include physical, chemical, and biological properties of the soil, as well as mercury levels in the soil and plants. The results showed that the soil quality index increased from 0.32 (low) to 0.62 (good). The organic C content increased from 0.91% to 2.16%, soil pH increased from 3.53 to 5.03, and the availability of phosphorus and potassium also increased. The population of methyl mercury-reducing bacteria increased 22.4 - 58.2 times, indicating improved microbial adaptation to the environment. Mercury content in plant tissue decreased drastically from 11.60 mg/kg to 0.11 mg/kg or a decrease of 99.05%, although still slightly exceeding the threshold. The conclusion is that reclamation with an organic approach and effective soil management not only improves soil fertility and quality, but also reduces the risk of heavy metal poisoning.
