Summary: Straw incorporation plays a vital role in regulating runoff and soil erosion of cropland. This study found that straw incorporation significantly reduced runoff and soil erosion on croplands with different degradation intensities. However, the benefits of straw incorporation were reduced with higher rainfall intensity and limited on strongly degraded croplands or under heavy storms. Soil hydrological properties and crop growth characteristics were also affected by land degradation and improved by straw incorporation, influencing runoff and soil erosion. Factors such as soil bulk density, rainfall intensity, and porosity were found to be important in the effectiveness of straw incorporation in controlling runoff and erosion. These findings are valuable for preventing land degradation and restoring degraded lands in semi-humid regions.

Summary: This study aimed to investigate the effects of rock fragment coverage on soil erosion and how these effects were influenced by rock fragment sizes. The results showed that total runoff and sediment concentration increased with rock fragment size. However, when the rock fragment sizes were less than 12.0 cm, the total runoff and sediment concentration were lower compared to bare soil. On the other hand, when the rock fragment sizes were larger than 12.0 cm, they increased the total runoff and sediment concentration in the wet run. This study highlights the importance of considering rock fragment size when assessing the effects of rock fragment coverage on soil erosion.

Summary: Through on-farm experiments and soil parameter analysis, it was found that retaining crop residues can improve soil saturated hydraulic conductivity and reduce the risk of phosphorus loss in purple soil. However, removing crop residues can lead to a decrease in soil aggregate stability and an increase in soil erosion and phosphorus loss risk. It is recommended not to remove crop residues in purple soil regions to ensure sustainable agricultural development.

Summary: Soil erosion by water is caused by the detachment and transport of particles or aggregates from the soil surface. The roughness of the soil surface affects surface runoff and soil erosion, with increasing roughness leading to reduced runoff and soil loss. However, the effects of both magnitude and orientation of soil surface roughness on runoff, infiltration, and soil erosion have not been extensively studied. This study compared different treatments of soil surface roughness to assess their impact on rainfall erosivity and erosion processes.

Summary: This study examined the combined effects of straw length and incorporation rate on reducing runoff and sediment under straw incorporation through laboratory experiments. Straw incorporation effectively reduced runoff and sediment yields, and the optimal effect was achieved at a straw length of 8-10 cm and an incorporation rate of 3.5 t.hm(-2). The reduction effect of straw length on sediment was weaker compared to the incorporation rate, which was the main factor affecting runoff yield during the erosion process.

Summary: This study assessed the dynamics of surface runoff and soil erosion in the Carpathians (Poland) based on over 30 years of plot studies, determined extreme soil erosion thresholds on agricultural slopes, and estimated the C-factor of the flysch mountains. Results showed significant relationships between soil erosion and precipitation and surface runoff, with precipitation thresholds for soil erosion of various magnitudes determined. The Revised Universal Soil Loss Equation highlighted the role of the C-factor in soil erosion studies, demonstrating changes of up to 69% in average soil erosion based on different C-factors. Long-term plot studies were emphasized for agricultural production and sustainable development in mountainous areas.

Summary: The EI30 index is an event erosivity index used for predicting unit plot soil loss. The index has issues of overpredicting small soil losses and underpredicting large soil losses. This problem arises from the failure of the USLE model to consider the direct effect of runoff on soil loss. The concept of erosivity density, along with the I30 index, provides an alternative erosivity index that incorporates the direct effect of runoff on soil loss.

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.
