Allelopathic Plant-Soil Interactions Mediated by Cover Crops

-

 


Allelopathic plant-soil interactions mediated by cover crops play a crucial role in sustainable agriculture by influencing weed suppression, nutrient cycling, and soil health. Certain cover crops, such as rye, sorghum, and mustard, release bioactive compounds (allelochemicals) through root exudates, leaf litter, or decomposing residues that can inhibit the germination and growth of competing weeds or pests. These natural biochemical interactions not only reduce the reliance on synthetic herbicides but also promote soil microbial diversity, organic matter enrichment, and improved soil structure. However, the effectiveness of allelopathy depends on factors such as cover crop species, biomass production, decomposition rate, and environmental conditions. Understanding these mechanisms enables farmers to strategically select and manage cover crops for integrated weed management and long-term soil fertility enhancement.

Carbon and Nitrogen in Mitigating and Adapting Agriculture to Climate Change

-
  Carbon and Nitrogen in Mitigating and Adapting Agriculture to Climate Change Carbon and nitrogen play pivotal roles in enhancing the resilience and sustainability of agricultural systems under climate change. Increasing soil organic carbon through practices like conservation tillage, cover cropping, and biochar application improves soil structure, water retention, and microbial activity, reducing greenhouse gas emissions while boosting crop productivity. Efficient nitrogen management—via precision fertilization, biological nitrogen fixation, and slow-release formulations—minimizes nitrous oxide emissions, a potent greenhouse gas, and enhances nutrient use efficiency. Integrating carbon sequestration and optimized nitrogen cycling supports climate-smart agriculture by improving soil health, increasing adaptive capacity to heat and drought stress, and sustaining long-term food security. These synergistic strategies not only mitigate climate change impacts but also enable farmers t...

Effects of Char and Amendments on Soil Properties and Sugar Beet Yield in Sandy Clay Loam Soil

-
  The application of char and soil amendments plays a significant role in enhancing soil properties and boosting crop productivity, particularly in sandy clay loam soils where nutrient retention and water-holding capacity are often limiting factors. Char, being rich in stable carbon, improves soil structure, aeration, and cation exchange capacity, which leads to better nutrient availability and reduced leaching losses. When combined with organic or inorganic amendments, char further enhances soil fertility by increasing organic matter content, improving microbial activity, and balancing soil pH. These improvements collectively support root development, nutrient uptake, and water use efficiency in crops such as sugar beet. Studies have shown that integrating char with amendments not only enhances sugar beet growth but also significantly improves root yield and sugar content by creating a more favorable soil environment. Thus, adopting char and amendment practices in sandy clay loam ...

Study on soil pressure of loose soil in cohesive soil tunnel considering soil arch effect

-
  The study on soil pressure of loose soil in cohesive soil tunnels considering the soil arch effect focuses on understanding how stress is redistributed around underground openings. In mixed ground conditions, where loose soil is embedded within cohesive strata, the natural formation of soil arches significantly influences lateral and vertical load transfer. By analyzing how arch-shaped stress paths reduce the direct pressure on tunnel supports, researchers can better predict deformation, optimize lining design, and improve the safety of underground structures. The interaction between material properties, overburden depth, and tunnel geometry plays a crucial role in determining the extent and efficiency of the soil arch effect in mitigating soil pressure.
