Soil organic carbon and its labile fractions in the conditions of water erosion on arable land of Chernozems area
Erika Balontayová, Viera Petlu¹ová, Peter Petlu¹, Juraj Hre¹ko, ©tefan Koco

The depletion of organic carbon in the topsoil and the reduction of the humic horizon leads to a decrease in soil productivity. This study focussed on evaluating the influence of water erosion on the quantity and quality of organic carbon (OC) in the topsoil. The determination of the differences in the OC with dependence on the soil thickness and the role of the soil texture in a depletion of OC in the humic horizon and its labile fractions were studied in four arable land localities (Haplic Chernozem, HC; Eutric Regosol, ER). The following carbon parameters were included: total organic carbon (TOC), labile carbon oxidisable by KMnO4 (CL),...
Comparison of two soil quality assessment models under different land uses and topographical units on the southwest slope of Mount Merapi
Retno Meitasari, Eko Hanudin*, Benito Heru Purwanto
Soil & Water Res., 2024, 19(2):77-89 | DOI: 10.17221/76/2023-SWR
This study aims to compare the soil quality indexing model by adding and weighting the soil under different land uses and slope positions on the southwest slope of Mount Merapi, Indonesia. Soil sampling was carried out based on a landscape analysis divided into four geomorphological units (slopes): upper, middle, lower and foot slopes. The research design was nested where the soil sample was located (surface soil 0–30 cm). Based on the research results, soil quality indices (SQI) of forest on the upper slopes is very high. SQI of dry fields on the middle, lower and foot slopes is low to medium. SQI of mixed gardens on the middle and lower...

Analysing the impact of climate change on evapotranspiration in a climate-sensitive region: Example of Central Anatolia (Türkiye)
Muhammet Azlak, Levent ªaylan
Soil & Water Res., 2024, 19(1):64-76 | DOI: 10.17221/107/2023-SWR
Evapotranspiration (ET) is one of the main components of the hydrological cycle and plays a crucial role for water resources. It is sensitive to climate change, and therefore, estimating ET under changing climatic conditions is essential in comprehending hydrological processes, particularly in agricultural water management. In this study, the impact of climate change on ET in the Central Anatolia region of Türkiye was assessed. For this purpose, RCP4.5 and RCP8.5 climate change scenarios based on two Earth System Models, HadGEM2-ES and MPI-ESM-MR, were employed for three future time periods: 2025–2049, 2050–2074, and 2075–2098. As...
Erosion risk analysis in a changing climate

Soil is an irreplaceable natural resource, with irreplaceable ecosystem functions. One of the greatest risks of soil degradation in the Czech Republic is accelerated erosion, which causes numerous damages to soil properties with negative impacts on the environment. The climate development in recent decades and its forecasts may further intensify these processes. This article deals with the analysis of the impacts of changes in selected climatic factors on the development of erosion processes, which in the conditions of the Czech Republic are influenced mainly by the development of precipitation in the growing season and the development of the values...
Digital soil mapping using machine learning-based methods to predict soil organic carbon in two different districts in the Czech Republic
Shahin Nozari, Mohammad Reza Pahlavan-Rad, Colby Brungard, Brandon Heung, Lubo¹ Borùvka
Soil & Water Res., 2024, 19(1):32-49 | DOI: 10.17221/119/2023-SWR
Soil organic carbon (SOC) is an important soil characteristic as well as a way how to mitigate climate change. Information on its content and spatial distribution is thus crucial. Digital soil mapping (DSM) is a suitable way to evaluate spatial distribution of soil properties thanks to its ability to obtain accurate information about soil. This research aims to apply machine learning algorithms using various environmental covariates to generate digital SOC maps for mineral topsoils in the Liberec and Doma¾lice districts, located in the Czech Republic. The soil class, land cover, and geology maps as well as terrain covariates extracted from the digital...
Assessing soil aggregate stability by measuring light transmission decrease during aggregate disintegration
Mikulá¹ Madaras, Robert Krejèí, Markéta Mayerová
Soil & Water Res., 2024, 19(1):25-31 | DOI: 10.17221/78/2023-SWR
Advancements in technology have recently enabled to assess soil aggregate stability (SAS) using digital devices. To address the need for a faster and more efficient method of measuring SAS, we have developed a simple yet effective approach using a specialized device. The innovative method named SlakeLight involves measuring the changes in light transmittance as aggregates undergo slaking. The device consists of the measuring chamber, which is placed on a LED light source with a surface-homogeneous distribution of luminosity. During the disintegration process of aggregates immersed in water, reduction in the light emitted to the photodiodes is proportional...
Soil pore structure and its research methods: A review
Nannan Wang, Tibin Zhang
Soil & Water Res., 2024, 19(1):1-24 | DOI: 10.17221/64/2023-SWR
Soil pore is an important part of soil structure. According to the causes of formation, soil pores can be divided into biological pores formed by animal movement and plant root development and non-biological pores formed by dry-wet and freeze-thaw alternation or artificial tillage. The soil pore structure affects the migration of water, gas, nutrients and so on in the soil, especially the macropores can also produce water or solute preferential migration. Studying soil pores is of great significance for predicting soil hydraulic properties, reducing groundwater pollution and soil nutrient loss. Based on previous studies on soil pore structure, this...
