The environmental and economic impacts of chemical fertilizer have encouraged farmers to integrate them with organic materials, an important nutrient management strategy for sustainable agriculture production. In the present study, we conducted field experiments to study the effects of nitrogen enriched compost (NEC) and mineral nitrogen (MN) fertilizer with a selected plant growth promoting rhizobacterial (PGPR) strain, Pseudomonas aeruginosa QS40, on productivity of sunflower and soil fertility. The results demonstrated that integrated application of PGPR with organic-inorganic N significantly increased shoot and root length, leaf area, total chlorophyll, head diameter, fresh biomass, straw-achene yield and N uptake in sunflower compared to unamended control and PGPR alone. The results also showed that integrated N biofertilizer regime enhanced soil microbial biomass, enzymatic activities and soil nitrogen contents. We also observed significant changes in rhizosphere soil pH, abundance of cultivable bacteria and arbuscular mycorrhizae fungi (AMF) root colonization. Treatment and year interaction was significant for dissolved organic carbon (DOC) and microbial biomass carbon (MBC) only. These results suggest that the efficiency of PGPR could be improved with increased availability of labile C substrate resource in NEC amended aridisol. We conclude that the application of NEC fertilizer with efficient PGPR biofertilizer may improve sunflower productivity and soil chemical and biological fertility in nutrient-poor agroecosystems of arid and semi-arid regions.

Muhammad Umair Hassan, Maria Batool, Taimoor Hassan Farooq, Muhammad Saleem Arif, Muhammad Aamer, Muhammad Ahmed Waqas, Gadah Albasher, Maryium Sajjad, Awais Shakoor

Summary: The global climatic energy balance has been altered by the emission of greenhouse gases (GHGs), such as CO2, CH4, and N2O, which has led to disturbances in terrestrial ecosystems. The production of biofuels from plant biomass is seen as a promising source of renewable energy. Soil acidification is a major obstacle to crop production and a significant source of GHG emissions. Dolomite (DM) is commonly used to neutralize soil acidity and control GHG fluxes. However, the effects of DM on GHG emissions under different environmental conditions are still unclear. This meta-analysis examines the impact of DM, climate zones, and soil properties on GHG emissions, filling in the gaps in knowledge.

Summary: In this study, a reciprocal transplant experiment was conducted along a climate gradient in Europe to investigate the effects of climate warming on the seasonality of metabolites produced by Sphagnum mosses and the consequences for peatland carbon uptake. The results showed that Sphagnum species exhibited consistent responses to warming, with shifts in their primary or secondary metabolites according to seasons. These shifts were also correlated with changes in gross ecosystem productivity, particularly in spring and autumn. The findings highlight the plasticity of plant metabolites and their ability to impact carbon processes in ecosystems.

Cover Crop Identity Differently Affects Biomass Productivity as well as Nitrogen and Phosphorus Uptake of Maize (Zea mays L.) in Relation to Soil Type

Mario Fontana, Sokrat Sinaj, Said Elfouki, Thomas Guillaume, Luca Bragazza

Summary: Integration of cover crops in agriculture rotation has multiple agronomic and environmental benefits. The impact of cover crop identity on cash crop productivity and nutrient uptake is still uncertain, especially with regard to soil types. Our experiment shows that leguminous cover crops improved nitrogen uptake by maize, while the effect on phosphorus uptake was less significant. Sandy soil had higher above- and belowground biomass of maize compared to clay soil. Overall, the presence of a preceding cover crop promoted or did not modify maize productivity in clay soil, but decreased aboveground productivity in sandy soil.

Summary: Microbial trophic interactions are important for understanding ecosystem functioning, but observing predation is challenging. This study demonstrates that machine learning algorithms can successfully predict microbial feeding links based on species traits and taxonomy. The model trained with the boosted regression trees algorithm performed best in predicting feeding links, and the predictions were robust against faulty predictors and new taxa. By combining traditional observations and DNA-based sampling strategies, machine learning can help study microbial food webs and soil biodiversity along ecological gradients.
