Clay-illuvial soils with argic horizon and developed from loess or other silty deposits constitute high-quality arable land owing to favourable physical and chemical properties. There are thus numerous reports on such soils, considering their structure, compaction, erosion, water and air properties. However, there is still a lack of quantitative studies on structure and physical properties on analogous soils under forests. The aim of this research was therefore a comprehensive description of the physical state, including structure, water and air properties, of a forest Retisol developed from loess. Morphographic, morphological and morphometric parameters of structure, selected physicochemical and water and air properties and also relationships among the obtained parameters were analysed for genetic horizons O, Ah, AE, E, Bt/E, Bt, BtC and C. The fi eld survey and soil structure images indicated that the studied forest soil had an undisturbed sequence of genetic horizons. The soil structure was shaped by soil fl ora and fauna causing bioturbation. Qualitative and quantitative structure analysis revealed that the O horizon had a loose arrangement, the Ah horizon had an aggregate crumb structure, the AE horizon had zones of an aggregate crumb structure and non-aggregate structure ( fi ssured or with channels), while the remaining mineral horizons showed essentially a non-aggregate structure with varying proportions and sizes of planes and biogenic pores (i.e. cracked or fi ssured structure and structure with channels, respectively). The morphometric and physicochemical parameters facilitated a detailed analysis of the Retisol’s physical state. The Retisol’s structure type and degree of aggregate development directly in fl uenced its hydraulic conductivity and water retention capacity. Therefore, under simulated precipitation, the soil water content and effective saturation varied mainly in the topsoil (O–E horizons) and virtually no changes were observed in the subsoil (Bt–C horizons). The research resulted in a comprehensive analysis of the physicochemical and morphometric parameters, their relationships, and structure images that were previously unavailable in other studies, covering the physical state of the entire pedon of a forest Retisol.

Our research aimed to present the properties of Luvisols developed from the loess of the Mie-chowska Upland, S Poland, as a favourable substrate shaping habitats for larch stands. Detailed characteristics covered ten research plots in mature stands, where Polish larch (Larix decidua var. polonica ) was the main species. On each research plot, a soil pit was dug and the separated genetic horizons were described. The diagnosis of the habitat type was developed using the Trophic Soil Index (SIG). Samples were taken from each genetic horizon for laboratory analysis. Basic physico-chemical properties (particle size distribution, pH, total organic C and total N content, available phosphorus content and sorption properties) were determined in the soil samples. As a result of the research, it was found that the Polish larch can create high-production stands in the fresh upland broadleaved forest sites (Lwy ż ś w) with the admixture of deciduous species (common beech Fagus sylvatica , English oak Quercus robur , common hornbeam Carpinus betulus , common sycamore Acer pseudoplatanus ). The investigated soils were described as Haplic Luvisols, which differed in the characteristics of humus horizons. The high share of larch (40–60%) growing on Luvisols does not negatively affect the properties of humus horizons and the degree of leaching of Luvisols created from loess. In the case of stands with a predominant share of larch (>60%), there is a tendency to deteriorate the properties of the humus accumulation horizons and the formation of the ectohumus horizon on the surface. SIG indicates that the tested soils shape the eutrophic fresh upland broad-leaved forest sites. The decrease in the SIG value in two cases is the result of the deterioration of the properties of humus horizons.

A marginal land de fi nition is a contemporary scienti fi c term that is constantly changing and un-stoppable. There are many ways in which marginal lands are referred to, unproductive lands, including waste lands, unutilized lands, idle lands, abandoned lands, or degraded land. In the present research, we tried to collect all Scopus-based publications in English from 1979 to 2022 years using crucial keywords: Marginal lands, Land degradation, and Agricultural land. We analyzed the most popular journals, top authors, top-cited papers, top countries, top-cited years, etc. A common way to identify ML is to use biophysical constraints related to agricultural productivity or bioenergy. For instance, using a multi-criteria decision approach based on Geographic Information Systems (GIS) and remote sensing, combined data on land use/land cover (LULC), slope, soil depth, erosion, moisture, water holding capacity, texture, and availability of nutrient to study the land suitability for agriculture in hilly zones. There is a high potential for applying remote sensing (RS) and geographical information systems (GIS) for the mapping and monitoring of marginal lands. In addition, the role of remote sensing (RS) and geographic information systems (GIS) in other disciplines around the world is signi fi cantly high. In contrast, in this research work, we fi nd out that the usage scale of RS and GIS technologies is not common all around the world on the given marginal land issues.

Carbon dioxide (CO 2 ) is a signi fi cant greenhouse gas (GHG) accounting for 60% of the total green-house effect. Soil respiration is a measure of the CO 2 released from soil. Rice was the largest contributing plant commodity of total emission by 12%. In the event of growing threats of global warming due to GHG emissions, reducing CO 2 emission by sequestering C in the soil is of supreme concernment. Improved management practices can rebuild C stocks in agricultural soils and help mitigate CO 2 emissions. A fi eld study to assess how organic soil amendments in fl uence soil respiration, C-organic content, and soil properties was conducted in upland paddy fi eld. Treatments were: chemical fertilizer (F1), combination of chemical fertilizer and cow dung manure (F2), chemical fertilizer and vermicompost (F3), chemical fertilizer and liquid vermicompost powder (F4), cow dung manure+biochar (F5), vermicompost+biochar (F6) and liquid vermicompost powder+biochar (F7). All treatments tested almost had the same pattern of respiration rates starting before the application of the organic soil amendment until three months after planting. The highest respiration rate was found at 1 month after planting. Soil amendment (F4 and F7) had the lowest soil respiration rates in some measurements. The highest organic C content at three months after planting was found in the F6 and F3 treatments. The most in fl uential factor on the respiration rate are soil moisture content and soil temperature. The results demonstrate the viability of vermicompost either in combination with chemical fertilizers or alone for soil amendment to maintain organic soil carbon for short period of time (~ 3 months).

Continuous irrigation causes soil salinity and decreases soil fertility. The purpose of this study is to fi nd methods that can prevent soil salinity. Thus, a soil column with 15 cm stack height, under maize cultivation and tape irrigation has been simulated by HYDRUS–2D. In order to assess the effects of different scenarios including tape location (stack/ditch), stack height (in drip and surface irrigation), using mulch and irrigation water salinity on salinity accumulation in root zone in different time frames. The results show placing tapes on ditch will increase soil primarily salinity (0.65 dS m –1 ) 8%, 8% and 10% lower than placing it on the stack after 1, 5 and 10 years. Also, height stack is not very effective for controlling salinity in both drip and surface irrigation. Because, assessing soil columns with 0, 10, 15 and 20 cm stack height showed neglectable difference between salinity both in short term and long–term scenarios (according to variance analysis test). Using mulch is an effective way to control salinity because it can decrease evaporation. After 1, 5 and 10 years of irrigation in mulch presence, salinity increased 34.5%, 42.8% and 50% lower than without mulch scenario. Also, irrigating soil by water of different salinities including 0.7, 1.7 and 2.7 dS m –1 showed 77.5%, 83.5% and 84.2% increase in salinity after 10 years ago.
连续灌溉导致土壤盐碱化，降低土壤肥力。本研究的目的是寻找防止土壤盐碱化的方法。利用HYDRUS-2D模拟了玉米种植和带灌条件下15 cm堆高的土柱。为了评估不同情况下，包括胶带位置(堆/沟)、堆高(滴灌和地灌)、覆盖和灌溉水盐度对不同时间框架根区盐分积累的影响。结果表明，1年、5年和10年后，沟渠布施比堆施能使土壤主要盐度(0.65 dS m -1)分别降低8%、8%和10%。此外，在滴灌和地灌中，高度叠加对控制盐度都不是很有效。因为，评估土壤柱在0、10、15和20 cm堆高的情况下，盐度在短期和长期情景之间的差异可以忽略不计(根据方差分析检验)。使用地膜是控制盐分的有效方法，因为它可以减少蒸发。覆盖1年、5年和10年后，土壤含盐量比不覆盖分别提高了34.5%、42.8%和50%。0.7、1.7和2.7 dS m -1不同盐度水灌溉土壤，10年后土壤盐度增加了77.5%、83.5%和84.2%。

Peatlands are recognized as one of the largest terrestrial carbon sinks and are pivotal in efforts to mitigate climate change. Given this, Indonesia has committed to managing its peatlands, which have been subjected to drainage, deforestation, fi res, and conversion for development. As of 2015, the Center for Agricultural Land Resources has mapped 107,344 ha of peatlands in South Kalimantan Province. However, in 2019, forest fi res destroyed 2,400 ha of land, leading to the decomposition of surface peat areas, land subsidence, and the release of carbon into the atmosphere as CO 2 . This study aimed to quantify the widespread loss of peat carbon using the PS-InSAR (Persistent Scatterer Inter-ferometric Synthetic Aperture Radar) technique. Speci fi cally, 66 Sentinel 1 SAR images of SLC were used to map subsidence in the peatland area between January 2019 and January 2021. The carbon content and bulk density of peatland were then quanti fi ed to estimate CO 2 emission. The results obtained through the PS-InSAR technique showed that the highest level of peat subsidence was at –50 mm year –1 in the Landasan Ulin Sub–district of Banjarbaru Regency. Furthermore, subsidence was identi fi ed in 6,920.5 ha of peatland in the study area. Subsidence, peat area, and carbon content data from SAR images, optical images, and peat soils were gathered through fi eld surveys and websites (GSOCMap and Zenodo) to estimate CO 2 emission. The estimated CO 2 emissions based on in–situ and website data were the highest at 0.29 t C ha –1 year –1 and 0.04 t C ha –1 year –1 in Beruntung Baru Sub-district, Banjar Regency, and Bumi Makmur Sub-district, Tanah Laut Regency, respectively.
泥炭地被认为是最大的陆地碳汇之一，在减缓气候变化的努力中发挥着关键作用。鉴于此，印度尼西亚已承诺管理泥炭地，这些泥炭地遭受了排水、森林砍伐、火灾和为发展而转换的影响。截至2015年，农业土地资源中心已在南加里曼丹省绘制了107,344公顷的泥炭地。然而，2019年，森林火灾摧毁了2400公顷的土地，导致地表泥炭区分解、地面沉降，并将碳以二氧化碳的形式释放到大气中。本研究旨在利用PS-InSAR(持续散射体间计量合成孔径雷达)技术量化泥炭碳的广泛损失。具体而言，使用66张Sentinel 1 SLC SAR图像绘制了2019年1月至2021年1月期间泥炭地地区的沉降图。然后定量测定泥炭地的碳含量和容重，估算co2排放量。通过PS-InSAR技术获得的结果表明，Banjarbaru摄政区Landasan Ulin街道的泥炭沉降最高水平为-50 mm year -1。研究区6,920.5 ha泥炭地存在沉降。通过实地调查和网站(GSOCMap和Zenodo)收集了沉降、泥炭面积和碳含量数据，这些数据来自SAR图像、光学图像和泥炭土，以估算CO 2排放量。基于现场和网站数据估算的CO 2排放量在Banjar县Beruntung Baru街道和Tanah Laut县Bumi Makmur街道分别最高，分别为0.29 t C ha -1年和0.04 t C ha -1年。
