Summary: The study found that using a fixed soil organic carbon (SOC) mass can lead to more consistent reduction of permanganate, but also results in a wider range of POXC values across different soils. While using a fixed SOC mass may improve the consistency of results, it can also decrease the repeatability compared to using a fixed soil mass.

Summary: Vegetation type has a significant impact on soil organic carbon storage. This study investigated the changes in soil organic carbon fractions and their driving factors for different vegetation restoration types. The results showed that the concentrations of soil organic carbon fractions were strongly influenced by vegetation types and soil depths. Soil biochemical and physicochemical processes were identified as important mechanisms contributing to soil organic carbon persistence.

Summary: The study found that intensification of shifting cultivation in northern Laos did not lead to a decline in soil organic carbon (SOC) stocks. Instead, the SOC stock under fallows in the intensive rotation category was significantly larger than under the extensive rotation category, likely due to inputs of dead root biomass from slashed vegetation. Additionally, fallow sites under intensive rotation had higher contents of permanganate oxidizable carbon (PDXC) in the topsoil compared to active fields, indicating the immediate effects of decreased litter input during cultivation periods.

Summary: This study measured the impacts of residuals-based soil amendments on soil health and vegetable yield for three urban soils. Results showed that amendment addition increased total C and N, reduced bulk density, and increased infiltration rates. Plant yield was similar to or less than fertilized controls for two soils. However, the greenhouse trial showed that all amendments resulted in increased yield in the most disturbed soil. The study demonstrates the efficacy of residuals-based amendments for restoring health and productivity to disturbed urban soils.

Summary: The study found that no tillage can improve soil structure and increase soil carbon, but alternating between no-till and deep-tillage may affect soil aggregation and carbon accumulation. Periodic deep-tillage can be as detrimental to soil structure as yearly reduced tillage, if not more.

Summary: The study found that prairie reconstruction can increase soil aggregation, total organic carbon, total nitrogen, active carbon and nitrogen, and mineralizable carbon and nitrogen in the first 8 years post-reconstruction, making the soil more similar to levels in a remnant prairie. However, from 8 to 13 years post-reconstruction, the number of soil health indicators declined, possibly due to historical land use, improvement of prairie reconstruction and management strategies, and ecological processes related to succession.

Summary: Composted organic materials, specifically olive leaves combined with sheep manure, were tested as soil amendments in a hedged olive grove in Portugal. The amendments significantly increased soil organic matter and fertility, with the highest dosage showing the most remarkable results. Certain soil properties, such as total nitrogen, carbon content, phosphorus, and zinc, experienced significant increases after one or two years of application. The compost also improved the soil's carbon stock and pH levels.

Summary: The study shows that permanganate oxidizable carbon (POXC) can be used as an indicator to monitor the impacts of silvicultural practices on soil properties. POXC concentration decreases with soil depth and is positively correlated with soil organic carbon (SOC), total nitrogen, and mass of soil woody detritus. However, the effects of silvicultural practices on POXC concentration vary across different sites, with herbicide treatments showing a significant decrease in POXC compared to control plots.

Summary: Permanganate oxidizable carbon (POXC) is a sub-pool of labile soil organic carbon (SOC) that can be oxidized by potassium permanganate (KMnO4). Prediction of POXC using FTIR-photoacoustic spectroscopy (FTIR-PAS) is mainly based on its high correlation with SOC. Unique spectral features of POXC were identified and four dominant peaks were found to represent the POXC fingerprint in the FTIR-PAS spectra.

Summary: Soil organic carbon (SOC) is crucial in pasture agroecosystem and is influenced by management practices like manure application and grazing intensity. This study investigated the impact of 13 years of different pasture management practices on SOC content and aggregation. Results showed that rotationally grazed pastures with organic manure had higher PDXC than unfertilized areas, and rotational grazing promoted the formation of large macroaggregates.

Summary: Soil aggregates play a crucial role in soil carbon sequestration and provide a habitat for microorganisms, including nematodes. Yet, little is known about the interactions between nematode community composition and soil carbon cycling across different aggregate fractions. This study aimed to investigate the effects of soil type and tillage intensity on nematode community distribution and their relationship with labile carbon pools. The results showed that soil type influenced the distribution of nematode feeding groups across different aggregate fractions, while tillage intensity had no significant effect. The correlation analyses revealed that predator-omnivore nematodes and permanganate oxidizable carbon were positively correlated in clay soils but not in silt loam soils. These findings highlight the importance of predator-prey dynamics and soil type in soil carbon accumulation and cycling.

Summary: The study found that different wheat genotypes exhibited varying patterns of root C allocation, influencing nitrogen cycling. Thicker roots released more C into soil, enhancing nitrogen mineralization and microbial biomass, which in turn increased nitrogen cycling enzyme activity and residue nitrogen uptake by wheat. Microbial community structure was strongly correlated with root C allocation patterns, with certain genera showing strong relationships with root C deposition and nitrogen uptake.

Summary: Improved forage-based fallows using grass-legume mixtures have the potential to address soil degradation issues in the Andean highlands. A pot study revealed significant overyielding in grass-legume bicultures compared to monocultures, with grass growth playing a bigger role in driving overyielding. Combining key functional groups, such as grasses and legumes, offers great promise for developing improved fallows to support soil health and productivity in Andean agroecosystems.

Summary: Healthy soils are crucial for sustainable agriculture, but degradation of soil health is a significant challenge in water-limited environments. Soil in arid and semi-arid regions often has low organic matter, fertility, and productivity, making it difficult to build up organic matter. Existing soil health assessment frameworks are not suitable for these environments and a new framework that links soil health with ecosystem functions is needed. The study also discusses management strategies, such as tillage and residue management, organic amendments, and cropping system diversification, for improving soil health in water-limited regions.

Summary: This study aimed to investigate the fine-spatial variation of soil properties and their impact on wheat productivity. The results showed that soil nutrients, texture, and subtle topographic changes were critical factors affecting wheat yield. Total carbon (TC) can serve as a reliable proxy for delineating management zones, but developing these zones relying solely on soil information is not straightforward in these soils.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
