Short summary
The research has been con conducted to estimate erosion risk over certain areas for land restoration. The result of the USLE showed that the annual rate of soil loss is in the range of 4.5Mgha-1y-1 in forestland and 65.9Mgha-1y-1 in cropland. The rate of soil loss in the cropland, which accounts for about 69% of the total soil loss in the study area, is very highly severe. This clearly shows that cropland should be prioritized to carry out land management practices such as minimum tillage.

Short summary
Most of selected soil properties showed highest variation with depth under forestland and lowest under cropland. There were no consistent spatial trends in CEC. The correlation matrix suggests OM, CEC and Ca are fundamental soil properties in both sampled depths. The Correlations among soil properties are determined by soil-forming processes than parent materials. However, it is difficult to explain on which sampled depths that correlation between soil properties would be stronger.

This paper focuses on collating legacy soil profile data and on the production of an updated national soil type map of Ethiopia, EthioSoilGrids version 1.0, using legacy data and a machine-learning approach. Given its quantitative digital representation, the map and the associated data make tremendous contributions to agricultural development planning and digital agricultural solutions, as well as improving the accuracy of global predictive soil mapping efforts.

The development of soils and landscapes can be complex due to changes in climate and land use. Computer models are required to simulate this complex development. This research presents a new method to analyze and visualize the results of these models. This is done with the use of evolutionary pathways (EPs), which describe how soil properties change in space and through time. I illustrate the EPs with examples from the field and give recommendations for further use of EPs in soil model studies.

The influence of the conversion from conventional tillage (CT) to conservation tillage (CS; including no tillage, NT, and reduced tillage, RT) on the saturated hydraulic conductivity (Ksat) of soils is not well understood and still debated. This study has demonstrated that quantifying the effects of tillage conversion on soil Ksat needed to consider experimental conditions, especially the measurement technique and conversion period.

Achieving global restoration targets requires scaling of context-specific restoration options on the ground. We implemented the Land Degradation Surveillance Framework in Rwanda to assess indicators of soil and land health, including soil organic carbon (SOC), erosion prevalence, infiltration capacity, and tree biodiversity. Maps of soil erosion and SOC were produced at 30 m resolution with high accuracy. These data provide a rigorous biophysical baseline for tracking changes over time.

We evaluated how sequestration of soil carbon changes over the long term after converting native grasslands into croplands and also from annual cropping into trees. Soil carbon was reduced by cropping but increased with tree planting. This decrease in carbon storage with annual cropping happened over centuries, while trees increase soil carbon over just a few decades. Growing trees in long-term croplands emerged as a climate-change-mitigating action, effective even within a person’s lifetime.

Zinc deficiency is a widespread nutritional problem in human populations, especially in sub-Saharan Africa (SSA). Crop Zn depends in part on soil Zn. The Zn status of soils from the Amahara region, Ethiopia, was quantified by measuring pseudo-total, available, soluble and isotopically exchangeable Zn, and soil geochemical properties were assessed. Widespread phyto-available Zn deficiency was observed. The results could be used to improve agronomic interventions to tackle Zn deficiency in SSA.

In this study geophysical observations from ground-penetrating radar with pedolith physical and geochemical properties from pedons excavated in four study areas of the climate and ecological gradient in the Chilean Coastal Cordillera are combined. Findings suggest that profiles with ground-penetrating radar along hillslopes can be used to infer lateral thickness variations in pedolith horizons and to some degree physical and chemical variations with depth.

Crop residues are widely available on-farm resources containing carbon and nutrients, but, as soil amendments, their decomposition does not always benefit the soil. We applied mixtures of crop residues that are chemically different from each other and found significantly increased soil organic matter and available nitrogen levels. Applying crop residue mixtures has practical implications involving the removal, mixing and reapplication rather than simply returning crop residues to soils in situ.

We developed a model to simulate long-term development of soils and landscapes under varying rainfall and land-use conditions to quantify the temporal variation of soil patterns. In natural landscapes, rainfall amount was the dominant factor influencing soil variation, while for agricultural landscapes, landscape position became the dominant factor due to tillage erosion. Our model shows potential for simulating past and future developments of soils in various landscapes and climates.

The objective of this study was to develop a soil grouping system based on spectral, climate, and terrain variables with the aim of developing a quantitative way to classify soils. To derive the new system, we applied the above-mentioned variables using cluster analysis and defined eight groups or "soil environment groupings" (SEGs). The SEG system facilitated the identification of groups with similar characteristics using not only soil but also environmental variables for their distinction.

Some 30 years after peak pollution-related soil acidification occurred in central Europe, the forest ecosystem of a small V-shaped mountain valley, UDL, was still out of chemical balance relative to the concurrent loads of anions and cations in precipitation. The spatial variability in soil solution chemistry provided evidence pointing to substrate variability, C and P bioavailability, and landscape as major controls on base metal leaching toward the subsoil level in N-saturated catchments.

The role of soil aeration in carbon sequestration in arable soils has only been explored little, especially at the farm level. The current study, which was conducted on 30 fields that belong to individual farms, reveals a positive relationship between soil gas transport capability and soil organic carbon content. We therefore conclude that soil aeration needs to be accounted for when developing strategies for carbon sequestration in arable soil.

Soil microbial communities play a key role in the cycling of carbon (C) in Arctic tundra ecosystems through decomposition of organic matter (OM). Climate change predictions include increased temperature and snow accumulation, resulting in altered plant communities and soil conditions. To determine how soil bacteria may respond, we sequenced soil DNA from a long-term snow depth treatment gradient in Alaska. Results indicate that bacteria produce less OM-degrading enzymes under deeper snowpack.

Zero Net Land Degradation (ZNLD) was proposed as a new global protocol to combat desertification. This framework aims at reducing the rate of global land degradation and increasing the rate of restoration of already degraded land. However, there is a narrow focus on land and soil, while an essential human dimension to the sustainability of drylands is lacking and should be more adequately tackled. I propose a complementary perspective based on the sustainable livelihood approach.

Savannas represent most of the world’s livestock grazing land and are suffering worldwide from bush encroachment and desertification. We studied soil under bush and grass in a bush-encroached savanna in Namibia. With bush removal, there were significant changes in soil chemistry and microbial community structure, but these changes gradually diminished with time. Our results indicate that the ecosystem can substantially recover over a time period of approximately 10 years following bush removal.

Surface coal mining disrupts large areas of land and eliminates valuable hardwood forests. Restoring the land to a sustainable forest ecosystem with suitable soils is the goal of reclamation. Soil microbial activity is an indicator of restoration success. We found hydroseeding with herbaceous forage species and fertilization doubled tree growth and microbial biomass carbon (an indicator of microbial activity) compared to non-hydroseed areas. Hydroseeding is an important component of reclamation.
