Summary: The study in Turkey's natural grasslands found that nitrogen fertilization can decrease soil bulk density, increase aggregate stability and EC, and improve soil porosity; increasing N application rates can enhance soil organic carbon, total nitrogen, C and N stocks, and boost microbial activity. Compared to the control group, the N250 treatment significantly increased microbial biomass carbon and nitrogen, while the N300 treatment increased C and N stocks.

Summary: This study shows that applying small amounts of biochar on marginal arable soils can increase plant available nutrients and crop yields, while reducing the availability of potentially harmful trace elements. However, the application of biochar did not have a clear impact on heterotrophic respiration.

Summary: The study found that crops sown on November 17 had the highest levels of bacteria, fungi, actinomycetes, soil microbial biomass carbon, dehydrogenase activity, and available nitrogen, phosphorus, potassium, and sulphur. When using nutrient sources, the combination of 75% recommended dose of fertilizers, 25% nitrogen from pressmud, Azotobacto, and phosphorus solubilizing bacteria showed the highest microbial population and nutrient content.

Summary: Different forest types have seasonal effects on soil microbial activities, with mature deciduous forests showing the most sustainable microbial activities. The diversity of forest environments and the multifactorial dependence of microbiological activities in forest soils warrant further research to better understand forest ecosystem functioning. Continued analysis of the interrelationship between soil parameters and forest types with different tree ages is necessary for a more comprehensive understanding.

Summary: The study found that the soils of the Maritime and sub-Antarctic regions have biological communities that can survive extreme environmental conditions. The soil microbial biomass tended to peak at 67-68 degrees S, coinciding with relative soil organic carbon and total nitrogen abundance, likely due to guano and excreta from sea birds and mammals. Despite having small and relatively inactive microbial communities, these soils efficiently convert organic resources into microbial biomass.

Summary: The quality of biochar and the addition of exogenous organic matter can influence soil CO2 emission. Food waste biochar serves as an easily available carbon source to soil microbes, while the addition of raw organic materials increases CO2 emission and carbon loss.

Summary: The study investigated the response of soil organic carbon (SOC) pools and their stock to organic and inorganic nutrient management in the Guinea grass and legume cropping system. It found that organic nutrient management resulted in greater SOC stocks and C sequestration compared to inorganic nutrient management. The grass-legume intercropping system can maintain long-term sustainability, enhance C sequestration, and offset the carbon footprint of the farm enterprises.

Summary: The study focused on the impact of rapid rewetting and slow rewetting of dry soil on soil respiration and nutrient cycling. Results showed that slow rewetting can increase the flush of respiration, but only if the second partial rewetting occurs 6 hours after the first.

Summary: In this study, an incubation experiment was conducted to investigate the effects of different manure sources combined with inorganic phosphorus on soil phosphorus availability and microbial biomass. The results showed that the combined application of poultry manure and inorganic phosphorus significantly improved soil physicochemical properties, increased soil phosphorus content, and enhanced microbial biomass.

Summary: Microbe-mediated carbon transformation is crucial for soil carbon sequestration, serving as a key strategy for long-term carbon neutrality. Evaluating the efficiency of microbial necromass accumulation in relation to plant carbon input or microbial respiration can provide insights into promoting soil carbon sequestration from an ecosystem perspective.

Summary: Diversified cropping increases soil organic carbon (SOC) stock and enhances soil quality by promoting the accumulation of SOC in large macroaggregates, stimulating microbial turnover, and improving aggregate stability. The increase in SOC sequestration is mainly driven by microbial biomass carbon, while the improved soil quality is mainly driven by soil organic carbon and aggregate stability. These findings suggest that diversified cropping can create win-win scenarios for agroecosystems.

Summary: Using a machine learning approach, this study found that the mean residence time of organic carbon in German agricultural topsoils was 21.5 years, with grasslands showing significantly higher MRTOC than croplands. Root-derived organic carbon inputs were identified as the most important variable for explaining MRTOC variability at a regional scale.

Summary: Healthy soils play a crucial role in planetary survivability, providing not only calories but also other essential functions. However, intensive agriculture is rapidly degrading soils and diminishing their capacity to deliver vital functions, highlighting the need to focus on the multiple functions of soils for long-term human welfare and the survivability of the planet.

Summary: Soil water repellency (SWR) can affect plant water use efficiency in rainfed cropping soils. Various factors such as drying method, incubation temperature, and specific surface area influence SWR response to soil water content. Maintaining consistency in drying methods and incubation temperatures is important to avoid methodological errors when studying SWR response to soil water content.

Summary: Factors affecting fertilizer decisions by grain growers are changing due to changing climatic conditions and volatility in global fertilizer and grain markets. Agronomic factors, especially rainfall, have the greatest influence on these decisions, while logistic factors become more important as farm size and fertilizer applications increase. Socioeconomic factors have become less influential over the years. Research and adoption activities should focus on agronomic and logistic issues for sustainable grain production.

Summary: Amelioration and management of large volumes of tailings resulting from alumina refining is a major challenge due to their high alkalinity and salinity. Blended byproduct caps, achieved by mixing tailings with other local byproducts, show potential as a cost-effective approach to reduce pH, salinity, and toxic elements. This study investigated the effects of blending alkaline bauxite residue with four byproducts on cap conditions, revealing that a combination of all four byproducts achieved the lowest pH and reduced concentration of toxic elements. Further improvements may be possible by adjusting addition rates, incorporating other materials, and extending leaching/weathering time.
