Summary: Stale seedbed preparation is an effective agronomic strategy for reducing weed seed banks, with seed bank reduction being proportional to the degree of soil crumbling induced by different tillage methods. Soil surface tillage can trigger weed seed germination and reduce the seed bank.

Summary: Pea is a widely cultivated leguminous plant that contributes to soil enrichment and crop rotations. Managing weed populations is crucial for pea production, and factors such as soil parameters, environmental influences, and management practices play a significant role in weed composition. Our study identified common weed species and revealed the influence of soil type, farming system, and data collection year on weed infestation.

Summary: This research examined the seed dormancy, germination, and soil seed bank dynamics of Eruca sativa, a versatile cruciferous species. The study found that E. sativa seeds can germinate in a wide temperature range and exhibit non-deep physiological dormancy at maturity. The germination of seeds is sensitive to water and salinity stress. When buried in soil, the seeds form a persistent soil seed bank, but emergence is hindered when buried deeper than 5 cm. This species' germination characteristics allow it to adapt to the harsh low-temperature climate of the Qinghai-Tibet Plateau.

Summary: The allelopathic activity of wheat through the production of BXZ compounds can affect the germination, growth, and physiological traits of surrounding plants and weeds. Wheat allelopathy can be potentially utilized through methods such as intercropping, mulching, incorporating crop residues, and applying wheat extracts. Some agricultural pests, fungal pathogens, and weeds have varying tolerance levels towards BXZ compounds. Selecting and breeding wheat genotypes with enhanced BXZ content can improve their defensive abilities.

Summary: Peanut is an important crop worldwide and is dominant in red soil areas of China. However, low phosphorus bioavailability in red soil severely affects peanut production. A field experiment was conducted to study the effect of green manure rotation on phosphorus bioavailability and peanut yield. The results showed that green manure treatments significantly improved soil pH, phosphorus components, and available potassium content. The phosphorus uptake of peanut was improved by green manure amendment.

Summary: Using ecologically sound methods to reduce weed seed banks, lower traditional herbicide application frequency, and achieve comparable results to conventional methods. Compared to traditional methods, integrated weed management can reduce herbicide applications by half and save costs and labor by 30%.

Summary: Predicting weed emergence in crop production systems is a global challenge that requires understanding mechanisms of weed ecology and trait evolution in response to climate change and altered agricultural practices. Seed dormancy, which controls germination by defining environmental conditions, plays a key role in weed soil seed bank persistence and seedling emergence timing. Integrating seed dormancy dynamics in variable field environments across generations is essential for more sustainable weed management strategies.

Summary: Weeds are a major constraint in crop production, and studies on the critical period of weed control (CPWC) focus on considering crop yield and weed density for specific management practices. Weed biomass is influenced by competition, and in organic or low-input farming systems, CPWC may be misleading and should be avoided. It is concluded that the critical timing of weed removal (CTWR) is more meaningful than CPWC.

Summary: In a 5-year field experiment in the Loess Plateau, China, the effects of long-term fallow tillage on soil microbial community structure and winter wheat yield were evaluated. Results showed that no-tillage and subsoiling tillage methods significantly improved soil moisture and organic carbon contents, as well as the diversity of microbial community. Deep plowing increased the metabolic functional diversity of bacteria and fungi. Both subsoiling tillage and deep plowing increased the yield of winter wheat, with deep plowing having the best effect.

Summary: Study focused on the importance of large carabids in removing weed seeds in organic fields within large-scale agricultural landscapes, considering both local and landscape-scale effects. Results showed that local intensity of management, crop characteristics, edge effects, and landscape composition and configuration all influenced the activity density of large carabids and consequently weed seed removal.

Summary: The study found that Trianum P provides good protection for the roots of scorzonera plants, helping to reduce the risk of infection by pathogens. The application of grapefruit extract, tea tree oil, and T-22 Trichoderma harzianum can increase the antagonistic activity of Pseudomonas sp., Bacillus sp., and certain saprotrophic fungi against soil-borne fungal pathogens.

Summary: This study monitored the long-term effects of moisture and substrate on seed persistence. The results showed that moisture levels were the main driver for seed persistence, and different species had different seed viability in the soil. The classification of soil seed bank type should consider both environmental factors and seed germination traits.

Summary: Knowledge of the soil weed seed bank is crucial for studying population dynamics and developing effective weed management programs. This study assessed the status of weed seed banks in two different sites and soils. The results showed that sampling six or nine sites with a zigzag shape can accurately estimate the abundance and density of weed species in the soil, contributing to integrated weed control efforts.

Summary: In this study, a four-year investigation on taro-earthworm coculture farming showed that using a unique crop-earthworm model can increase taro yield, economic value and net income. The activities of earthworms reduced the weed seed bank, mitigated weed infestation, and decreased the need for weeding. This research demonstrates the ecosystem services provided by earthworms in agricultural systems, and how the coculture of taro and earthworms enhances crop production by reducing weed infestation and improving environmental quality.

Summary: The study summarizes the effects of elevated O-3 on soybean growth, yield, and quality, showing that soybean growth is inhibited under high O-3 concentrations, with accelerated chlorophyll degradation and increased foliar injury. Root biomass is more sensitive to O3, and ozone exposure results in a significant decrease in soybean seed yield.

Summary: Vermicompost application in intensive Pinelliaternata planting systems improves yield and soil properties, including total phosphorus, urease, and soil catalase contents. The impact of vermicompost and chemical fertilizer on soil microbial communities differs, with urease and total potassium as major drivers for bacterial community, and total phosphorus, total nitrogen, acid phosphatase, and total potassium as major drivers for fungal community.
