Summary: This study quantified the effects of wheat straw length and coverage on infiltration, runoff, and sediment yield. The results showed that increasing straw coverage increases infiltration rate and reduces runoff and sediment yield, while increasing straw length reduces infiltration rate and increases runoff and sediment yield. The optimal marginal benefit of straw is achieved when the straw cover is 3.5 t center dot hm(-2). Wheat straw mulch can effectively increase infiltration and reduce runoff and sediment yield, making it critical for sustainable agriculture and ecology on sloping land.

Summary: Water loss through surface runoff is a problem for rainfed agricultural lands in the Mediterranean region. Straw-mulch cover (SMC) is effective in mitigating the impact of raindrop splashing, but its use is limited due to the demand for crop residue as livestock feed. Synthetic polyacrylamide (PAM) has become a common alternative. This study used on-site rainfall simulation to compare the efficiency of PAM and SMC in controlling runoff from foxtail millet fields under different seasonal conditions, and found that SMC was more effective in reducing runoff in autumn and spring.

Summary: This study evaluates the hydrological effects of mulching in forest ecosystems after a wildfire in Central-Eastern Spain. The results show that mulching with wheat straw had a significant positive impact on water infiltration, reducing surface runoff and soil loss compared to mulching with wood chips or leaving the soil untreated.

Summary: The study investigated the impacts of wheat straw length and coverage on soil infiltration, runoff, and sediment production under different mulching methods. Results showed that runoff and sediment production varied with different straw lengths and coverage rates in both surface mulching and mixed mulching methods.

Summary: Mulching is widely recognized as an effective soil and water conservation measure globally. A meta-analysis of 90 publications demonstrates that mulching significantly reduces runoff and soil loss, with straw and wood-based mulch being more effective. Increasing mulch coverage and application rates further decrease runoff and soil loss.

Summary: This study analyzed the effect of straw mulching on the composition of myxobacterial community and found that straw mulching did not significantly influence the alpha-diversity of myxobacteria, but had a significant impact on the community composition. Total organic carbon was identified as the most important factor affecting the myxobacterial community structure. Furthermore, the study revealed that the myxobacterial community structure contributed to the alpha- and beta-diversity of soil bacterial community, particularly in specific soil aggregate fractions.

Summary: Straw mulching has been shown to be effective in soil and water conservation, but its impact on rill erosion has been rarely studied. This study evaluated the effects of straw mulching on rill development and found that it can delay runoff initiation and reduce soil loss. However, the effectiveness of straw mulching in controlling erosion does not increase linearly with mulching rate, as higher mulching rates can lead to increased rill erosion. Straw mulching also alters the course of rill development.

Summary: This study evaluated the breeding of alfalfa for intercropping with corn by selecting surviving plants from previous varietal evaluations. The results showed that the polycross and hybrid entries treated with a combination of prohexadione, fungicide, and insecticide had a significantly higher alfalfa stand density after corn harvest compared to parental entries. These findings highlight the effectiveness of plant selection in developing alfalfa germplasm with improved survival under corn, which should stimulate further breeding work to enhance intercropping systems.

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: The optimal allocation of agricultural water and land resources is crucial for farmers' economic benefits, carbon sequestration, and water resource conservation. This study developed a novel water-carbon-economy coupling model and applied it to a real farm, demonstrating its effectiveness in achieving the optimal allocation of water and land resources. The model balances economic, environmental, and social benefits.
