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
