Summary: The study examined the impact of soil texture and degree of compactness on total porosity and distribution of macro-, meso- and micropores. It found that total porosity and macroporosity are dependent on compactness and silt plus clay content, while meso- and micropores are mainly affected by particle size distribution. The findings suggest that increasing compactness may reduce total porosity and macroporosity, with meso- and micropores being more sensitive to changes in particle size distribution.

Summary: Gas flow in shale nanopores is crucial for shale gas exploitation. Organic matter, with its gas storage ability, plays an important role in gas shale reservoirs. Existing permeability models mainly focus on specific factors such as pore diameter or mathematical distribution, rather than pore size distribution. Our research shows that the Kapp curves of organic matter exhibit transition steps from transitional flow to slip flow, with porosity, dominant pore diameter, and frequency being the main factors affecting organic matter's Kapp.

Summary: Sustainable management of grazinglands requires understanding how management practices affect livestock movements. An experiment was conducted to compare the foraging behavior of cattle in a collaborative, adaptive rangeland management (CARM) system and a traditional rangeland management (TRM) system. CARM cattle showed more linear grazing pathways, slower grazing speed, and longer grazing bouts early in the season compared to TRM cattle.

Summary: Maps of erosivity play a critical role in soil conservation efforts, but current maps in the United States and globally face issues. In this study, the isoerodent map of the United States was updated using extensive precipitation measurements and it was found that topographic effects have a significant impact on erosivity. Benchmarking comparisons also revealed that existing maps underestimate erosivity. Reevaluation of correction methods is needed.

Summary: Recent observations and climate change projections indicate that changes in rainfall energy, intensity, duration, and frequency will amplify erosion rates globally. However, the future changes in erosive power of rainfall are largely unknown at finer-resolutions and local scales. This study calculates erosivity in the southeastern United States using a 15-min precipitation dataset and projects an increase in precipitation, erosivity, and erosivity density for the future. The findings suggest that changes in rainfall intensity are driving the change in erosivity.

Summary: This study investigates the effects of erosion degradation and long-term manure fertilization on soil properties and crop yield in Northeast China. Results show that erosion degradation and manure fertilization have lasting impacts on soil physical structure throughout the soil profile, while their effects on soil nutrient properties are focused in shallow layers. Manure fertilization significantly improves soil functional index (ISI) and maize yield for degraded soils. Erosion degradation has a greater influence on ISI and maize yield than manure fertilization.

Summary: This study investigates the structural strength of the Loess-Paleosol Sequence (LPS) and finds that the strength tends to increase with burial depth, with the loess layer weaker than the paleosol layer. The microstructure of the LPS also undergoes significant transformations with increased burial depth, transitioning from an overhead structure to a matrix structure. These findings highlight the importance of climate conditions on the structural strength of the LPS.

Summary: This study aimed to evaluate the impact of long-term nutrient management practices on P fractions and P adsorption-desorption behaviour of an acid soil with a soybean-wheat cropping system. The findings revealed that amorphous Fe and Al, which play a significant role in P fixation, increased due to cultivation. The NPK+Lime treatment offered the most balanced approach, improving both crop yield and P uptake while effectively managing P dynamics in the soil. On the contrary, long-term application of NPK+FYM in an acid soil may result in faster P saturation of adsorption sites and increase the chances of leaching and eutrophication. Tailored P fertilization strategies should be developed to better utilize the PFe and PAl fractions and supplementing applied P.
