Summary: This study found that the application of manure compost can significantly increase the shoot dry weight of tomato plants, soil organic matter, and soil-exchangeable K and Mg. Moreover, it can also increase bacterial diversity and richness, and positively affect the relative abundance of Lysinibacillus, thereby promoting tomato growth.

Summary: A 10-year study in a corn-based cropping system showed that long-term nitrogen fertilizer application had no detectable effect on soil organic carbon (SOC), nitrogen supply capacity, and aggregate stability. However, it did increase crop yield and residue carbon inputs. Assuming a constant harvest index of 0.5 would overestimate actual residue carbon returns.

Summary: Crop residue return and chemical N fertilization have significant effects on soil N availability by altering SON and its mineralization, leading to increased SON content and enhanced microbial and enzyme activities. The combination of appropriate N fertilization and crop residue return has great potential in improving soil N availability.

Summary: Low precipitation and poor soil quality are the main factors limiting wheat production in the Loess Plateau region of China. Straw incorporation and applying inorganic/organic fertilizers can effectively improve soil fertility and increase wheat productivity in semi-arid areas. Long-term in-situ experiments have shown that straw incorporation along with the addition of inorganic/organic fertilizers is an effective management strategy for enhancing soil fertility and wheat yield.

Summary: Increases in nitrogen deposition have the potential to impact the organic carbon cycle in soil. The effects of nitrogen addition on soil organic carbon pools are inconsistent, highlighting the need for quantifying the response of organic carbon pool distribution to nitrogen addition. Furthermore, the influence of adding a mixture of organic and inorganic nitrogen on organic carbon pool distribution and stabilization in grassland soil remains unclear.

Summary: The loss of nitrate-nitrogen (NO3--N) in citrus orchards is mainly caused by the large amount of nitrogen fertilizer input. The primary source of runoff NO3--N loss is soil organic nitrogen (SON) mineralization, and the potential and rate of soil N mineralization are key factors impacting NO3-N loss. Organic manure application increases NO3-N loss derived from SON, while green manure mulching effectively reduces NO3--N loss. Regulating SON mineralization plays a critical role in controlling NO3--N pollution in citrus orchard catchments.

Summary: This study analyzed 67 samples to reveal the differences in OC and OM in different particle-size fractions and evaluated the impact of conversion coefficients on OM. The research demonstrated that OM determinations varied not only due to changes in OC and OM content, but also because of alterations in OM stoichiometry and reactivity.

Summary: Through Life Cycle Analysis, it was found that open-field zero-miles tomato production is the best option environmentally, while heated greenhouses for zero-miles production have higher environmental impacts. Furthermore, transport efficiency is more important than transport distance, and the efficiency of agricultural management and transport strategies will affect environmental burdens.

Summary: This study found that eight Bacillus strains isolated from the root of F-BP peppers showed strong antagonistic effects against both Botrytis cinerea and Verticillium dahliae. B. siamensis strain exhibited the best efficacy against both pathogens. Infection tests on pepper fruits and plants showed that B. siamensis could control B. cinerea through direct action and activation of plant defenses, while also significantly reducing the occurrence of V. dahliae root infection through direct action and activation of jasmonic acid defense response.

Summary: Euphorbia fulgens, an ornamental species cultivated in Europe and endemic to Mexico, has been studied to determine its distribution, describe its habitats, and analyze the genetic diversity and structures of its wild populations. The results show high genetic diversity and low genetic differentiation among populations, suggesting that the species is an ancestral population that has just started to differentiate genetically. The information obtained from this study can be used for conservation programs related to human activities that pose a threat to its habitats.

Summary: This study analyzed the mechanisms by which Rhizobium leguminosarum strains alleviate drought stress in wheat plants. The results showed that two strains (LBM1210 and LET4910) significantly improved the growth parameters and chlorophyll content of the plants. They also reduced the levels of MDA, H2O2, and ABA. Furthermore, the two strains regulated the expression of different genes involved in drought stress response, while ethylene metabolism did not seem to be involved.

Summary: The inter-row soils in conventionally run citrus orchards in Eastern Spain lose fertility as a consequence of machinery traffic and herbicide use. Two grass-cover management alternatives, spontaneous plants and fescue, were established and monitored for their effects on soil fertility. Fescue ground cover resulted in lower soil temperatures, higher water content, and increased rhizodeposition. Spontaneous plants improved the chemical fertility and physical fertility of the soil. However, neither grass cover enhanced the organic carbon or overall fertility. Increased nitrogen inputs are recommended for improved soil fertility.

Summary: This study optimized the combination rates of three types of treated bio-residues in two microcosm trials and found that the combination of bio-residues improved plant growth and soil biological activity. However, while adding compost and biochar, as well as biochar and anaerobic digestate, increased the concentration of essential nutrients in crops, the nitrogen concentration decreased due to nitrogen competition between plants and soil microbiome.
