Summary: Conservation agriculture based on no-tillage and crop rotation can enhance soil health by increasing soil organic carbon stock, soil microbial biomass carbon, arbuscular mycorrhizal fungal root colonization, and soil microbial respiration. The combination of no-tillage with triennial rotation showed the highest soil organic carbon stock, soil microbial biomass carbon, arbuscular mycorrhizal fungal root colonization, and soil microbial respiration.

Summary: This study investigated the effects of tree thinning and climate on microbiological and enzymatic soil properties in an Aleppo pine forest. The results showed that 60% thinning improved soil microbial and enzymatic properties, but the effectiveness varied depending on soil organic matter content and texture. Therefore, moderate thinning can be an effective practice for improving soil quality in the Mediterranean area.

Summary: Soil microbial communities play a crucial role in biogeochemical cycling and greenhouse gas emissions, and are affected by crop and soil management practices. It is important to study the impact of conservation agriculture on soil bacterial diversity, nutrient availability, and greenhouse gas emissions in rainfed semi-arid regions. This study conducted over 10 years found that conservation agriculture improves soil bacterial diversity, enzyme activity, and nutrient availability, and reduces greenhouse gas emissions, contributing to climate change mitigation and sustainability.

Summary: Insufficient characterization of soil organic carbon dynamics in semi-arid climates contributes uncertainty to estimates of soil organic carbon sequestration. This study estimated changes in soil organic carbon due to variations in manure management, tillage regime, winter cover crop, and crop rotation in southern Idaho, USA. The DNDC model adequately simulated empirical soil organic carbon and biomass carbon measurements, but encountered specific issues when extended to a longer simulation period. By 2050, model forecasts suggested triticale cover crop resulted in soil organic carbon accrual, with a quadratic relationship observed in the effects of manure application on soil organic carbon.

Summary: The study aimed to investigate the bioremediation effect of two biostimulants extracted from okara on soil contaminated by imazamox. Both biostimulants enhanced soil biochemical activity and microbial population, with the one containing a higher percentage of low-molecular-weight proteins showing greater stimulation. Application of these biostimulants reduced the inhibition of biological properties in polluted soil, with the biostimulant containing more low-molecular-weight proteins being more effective.

Summary: Based on a global field survey, it was found that soil carbon content is closely associated with the relationship and ratio between microbial diversity and biomass in soils across different ecosystems and climate types. Particularly, the ratio of soil microbial diversity to biomass is higher in arid environments and lower in C-rich cold environments. The study indicates that reductions in soil carbon content due to land use intensification and climate change could lead to significant shifts in the microbial diversity-biomass ratio, impacting various soil processes.

Summary: The study revealed that high boron doses promoted boron accumulation in soil, leading to harmful concentrations that impacted soil biodiversity. There was a close interaction between boron and organic labile fractions, increasing boron availability in soil solution. Organic amendment did not enhance boron soil adsorption, but facilitated boron plant uptake, and the highest boron dose had a detrimental impact on plant physiology, eventually causing lethal effects on the plants.

Summary: The study identified dominant proteins in soil related to carbohydrate metabolism, DNA repair, and lipid metabolism across a wide range of climates, vegetation types, and soil conditions. Vegetation type, climate, and key edaphic properties were found to influence the proportion of important proteins involved in biogeochemical cycles and cellular processes in soil. Additionally, protein-based taxonomic information showed greater resolution in detecting significant correlations with environmental variables compared to 16S rRNA gene sequencing.

Summary: The structure and function of soil microbiomes in urban greenspaces are largely uniform worldwide. Urban soils contain a higher proportion of fast-growing microbes and lower levels of ectomycorrhizal fungi compared to natural ecosystems. City affluence, management practices, and climate are key factors influencing urban soil communities.

Summary: This study demonstrates that the responses of soil microbial communities in Mediterranean croplands to biochar amendment are more significant than to climate manipulation. Soil chemical properties, enzyme activities, and the relative abundances of bacterial populations are not responsive to the interaction of biochar and climate manipulation, while the predicted functionality of the bacterial community is modified by both factors. Climate manipulation produces changes in the composition of the soil fungal community, with a significant impact on soil beta-glucosidase activity and microbial biomass.

Summary: The control and development of plant growth promoters is essential for the agronomy industry. This study used untargeted metabolomics to investigate the metabolites responsible for the biostimulant effects of three bacteria. The results revealed several metabolic pathways, including the pentose phosphate pathway, tryptophan metabolism, zeatin biosynthesis, vitamin B6 metabolism, and amino acid metabolism, that are related to bacteria biostimulant activity. Additionally, 14 metabolites were identified as biomarkers of the biostimulant capabilities.

Summary: Irrigation with desalinated seawater (DSW) is a potential solution for water scarcity in semiarid regions, but it may harm agricultural ecosystems due to high phytotoxic element content. Lemon trees showed a decline in physiological parameters and accumulation of boron, while apricot trees were not negatively affected. DSW irrigation increased soil microbial biomass and had positive effects on the crop-soil system.

Summary: Fungi and bacteria are the dominant groups of soil microbial communities worldwide. They play a crucial role in regulating carbon cycling by controlling the turnover of soil organic matter. This study provides the first quantitative and high-spatial-resolution map of soil fungal proportion across terrestrial ecosystems, revealing striking latitudinal trends where fungal dominance increases in cold and high-latitude environments. The study also found a strong nonlinear response of fungal dominance to environmental factors, such as mean annual temperature and net primary productivity. These findings have important implications for improving predictions of soil organic matter turnover under current and future climate scenarios.
