Summary: Tillage management is a crucial factor in determining soil quality, which is vital for sustainable agriculture. Through investigating the effects of different tillage managements on soil properties, it was found that subsoiling tillage had positive effects on soil organic carbon and total nitrogen, while rotary tillage increased soil water content. The soil quality index was significantly correlated with grain yield. Therefore, evaluating soil quality through sensitive indicators can provide a scientific basis for selecting appropriate tillage management and assessing soil quality.

Summary: There are controversies regarding the edaphic factors that may interfere with the occurrence of Rhizoctonia root rot in soybean. This study identified the chemical and physical soil attributes associated with the occurrence of the disease in a subtropical environment. The results showed that acidic soil attributes were most associated with the incidence of Rhizoctonia root rot in soybean.

Summary: In no-tillage areas, cover crops provide a continuous supply of organic matter and improve soil structure. The study found that cover crops significantly influenced soil physical attributes, with Brachiaria and Pearl millet showing lower soil resistance and density. Millet, when grown alone or intercropped with other cover crops, demonstrated the best soil physical quality indicators.

Summary: The study found that in the unburned sugarcane harvesting system, soil CO2 emission was lower and soil moisture was higher, while in the burned sugarcane harvesting system, soil CO2 emission was higher but soil temperature was higher.

Summary: The study found that over 25 years, reclaimed surface coal mines showed increases in soil organic carbon and cycling of basic cations, while soil structure development decreased and pH levels also dropped. These changes suggest that surface horizons are more influenced by soil forming factors than spoil, which is more affected by the random conditions of reclamation.

Summary: Biochar application can have positive effects on soil properties and crop productivity. It can increase soil pH, cation exchange capacity, and organic carbon content, while reducing bulk density and increasing porosity. The impact on microbial diversity varies depending on the feedstock and soil texture. However, the increase in crop productivity is only significant in fine and coarse textured soils.

Summary: This research evaluated the status and spatial variability of soil chemical properties in agroecosystems of Choke Mountain, Ethiopia. The results showed that soil chemical properties were below their threshold values in all agroecosystems. Soil pH, exchangeable acidity, electrical conductivity, and exchangeable potassium showed strong spatial dependence, while SOC and TN had moderate spatial dependence. The study emphasizes the need for specific soil management strategies to improve soil conditions.

Summary: The study conducted in southern Portugal analyzed the spatial and temporal variability of soil properties in three farm fields over three years using Factor Analysis and Discriminant Analysis. It was found that chemical composition had the most significant impact on temporal discrimination, while texture and nutrient availability were the dominant factors in spatial differentiation, indicating the potential for assessing patterns of soil function variation over time and space.

Summary: Relating biological patterns to the physical environment is increasingly explored to identify ecological status and address global biodiversity crisis. This study conducted on the north-eastern coast of India assessed the patterns of free-living marine nematodes (FMN) and their relationship with environmental factors. The results indicated that organic carbon and salinity were the most correlated variables with FMN patterns, suggesting the importance of considering spatial and temporal variability in using FMN as bioindicators.

Summary: The excessive use of nitrogen fertilizer has negative effects on wheat production. Machine learning techniques were used to identify the factors that could potentially improve nitrogen recommendations. The analysis relied on a database that included a formula fertilization project, the second soil census of China, and cultivated land fertility evaluation. The results showed that the soil nitrogen supply capacity was the main factor controlling wheat grain production, and factors such as soil types, precipitation, and temperature showed a positive correlation with the soil nitrogen supply capacity. Therefore, it is important to focus on preserving optimal soil fertility by considering the soil nitrogen supply capacity instead of solely relying on the soil nitrogen content as a standard for fertilizer management.

Summary: This study found that soil physical, chemical and microbiological attributes affect greenhouse gas emissions in forest ecosystems. Compared to pine plantations, native forests have lower density, higher porosity and moisture, and better microbiological attributes, leading to stronger methane consumption. Therefore, improving soil physical attributes may contribute to increasing methane consumption and reducing greenhouse gas emissions in forest ecosystems.

Summary: The study evaluated the spatial and fractal variability of selected soil macro- and micronutrient elements across different slope positions, with higher organic carbon and nitrate nitrogen content observed at the toe slope. This suggests potential nutrient mobility with water flow, and the results may serve as a useful tool for precision agriculture recommendations across different slope positions.

Summary: This study used Markov geostatistics to analyze the three-dimensional spatial distribution characteristics and influential factors of soil nitrogen in coal mining subsidence areas. The results showed significant variations in nitrogen content at different soil depths, influenced by factors such as mining subsidence, rainfall, irrigation, fertilization, and management mode.
