Summary: Conservation agriculture-based sustainable intensification (CASI) technologies, including zero-tillage with crop residue retention on the soil surface, diversified cropping systems, and balanced nutrient management, are considered effective strategies for ensuring food security in South Asia. This study evaluated the short-term impact of contrasting tillage and cropping systems on total organic carbon (TOC) and its fractions, showing that the rice-maize cropping system and zero-tillage practices significantly increased TOC and its components compared to rice-wheat system and conventional tillage methods. These findings suggest the importance of crop management practices in influencing soil organic carbon dynamics in agricultural soils.

Summary: The study found that long-term grazing in desert steppe did not significantly reduce total SOC, but significantly decreased labile and recalcitrant SOC fractions under high grazing intensity. Additionally, soil prokaryotic communities were not significantly impacted by grazing intensity, but sensitive OTUs were found to cluster in modules reflecting different grazing intensities, indicating a response to grazing. Association networks of prokaryotic OTUs and organic C fractions highlighted the significance of rare microbial taxa in relation to SOC fractions, suggesting that grazing intensity can act as environmental filtering and affect soil microbial diversity and SOC fractions.

Summary: This study investigates the interactive effect of elevated CO2 and warming on the carbon storage in soil organic C fractions. The results show that elevated CO2 increases plant-C in the fine particulate organic C fraction, but warming plus elevated CO2 does not affect its allocation. Moreover, elevated CO2 increases plant-C accumulated in the mineral-associated C fraction. However, climate change may not alter the soil organic C stock, but can accelerate the turnover of plant-derived C.

Summary: Converting natural forests to plantations can lead to significant loss of soil organic carbon and threaten soil microbial communities. This study investigated the impact of converting natural forests to a tea plantation on soil organic carbon storage, microbial community composition, C-degrading enzyme activity, and the abundance of C-degrading microbial functional genes. The findings suggest that the shift in microbial community composition and function associated with land-use change is mediated by changes in the labile carbon pool.

Summary: Cover crops can increase carbon inputs to agricultural soils and mitigate climate change through enhanced soil organic carbon storage. This study investigated the fate of belowground carbon inputs associated with different root traits in mineral-associated organic carbon (MAOC) and particulate organic carbon (POC) pools. Results indicated that root morphology played a key role in determining rhizodeposition carbon, and the remaining MAOC and POC were positively correlated with belowground inputs in absolute terms. Furthermore, the importance of rhizodeposition and root morphology for longer-term carbon stabilization was found to be greater than substrate C:N ratio.

Summary: The rapid expansion of rubber plantations has had significant impacts on the carbon stocks of ecosystems, with potential consequences for climate change mitigation and future carbon fluxes. This meta-analysis examines the effects of different land use changes based on rubber plantations on soil physicochemical properties, particularly soil organic carbon (SOC) pools. The study finds that forest-to-rubber conversion leads to reductions in SOC, microbial carbon (MBC), total nitrogen (TN), and total magnesium pools, while rubber intercropping with different crops increases SOC and MBC pools. The effects of rubber intercropping are more pronounced in surface soil and at lower altitudes, and intercropping plantations can help alleviate soil acidification. Changes in SOC response ratio are influenced by variations in soil clay, bulk density, and C/N ratio.

Summary: Zinc deficiency poses a global threat to human health, particularly due to the reliance on zinc-poor cereal-based diets. Wheat, as a staple grain, is consumed by a considerable portion of the global population. However, the zinc concentration in wheat grain falls short of the requirement for human health, highlighting the need for biofortification. Agronomic biofortification, through fertilizer management and foliar application, can increase the zinc concentration in wheat grain and improve its bioavailability. However, there are challenges in enhancing zinc accumulation and transportation during grain filling. Biofortification of zinc in wheat should be studied using distinct biomarkers to assess its efficacy.

Summary: This study investigated the effects of innovative nitrogen (N) and zinc (Zn) management approaches on fodder maize production. The results showed that applying 50% of recommended N dose through urea, along with dual foliar sprays of nano-urea, achieved comparable productivity to 100% urea application. Among the Zn managements, both foliar and soil applications of conventional ZnSO4 recorded similar green and dry fodder yields, but foliar application of ZnSO4 was superior in terms of qualitative attributes. Maize subjected to the integrated nitrogen and zinc management strategy exhibited elevated protein content and reduced fiber fractions.

Summary: The current widespread and intensive soil degradation in India is mainly caused by factors such as population growth, industrialization, improper agricultural practices, and urban sprawl. This poses threats to livelihoods and the socio-economic stability of the country. Inappropriate agricultural practices, including excessive tillage, excessive use of fertilizers and pesticides, are among the major contributors to soil degradation. Soil science plays a crucial role in addressing this issue, but there are knowledge gaps that need to be addressed.

Summary: The simultaneous occurrence of biotic and abiotic stresses in salt-affected agroecologies can affect crop performance. This study found that the plant-microbe interaction with effective rhizobacteria can effectively manage these stresses. Certain rhizobacterial isolates demonstrated biocontrol and plant growth promotion capabilities, inhibiting the growth of fungal phytopathogens and promoting plant growth through P and Zn solubilization. Applying these native rhizobacteria also reduced disease severity, increased grain yield and P uptake in crops, making them an effective option for managing multiple stresses in salt-affected agroecologies.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

Summary: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.
