Summary: This study compared the effectiveness of natural and technical phytoremediation approaches in decontaminating oil-polluted soil. The research examined 20 oil-contaminated sites of different contamination types and levels. Technical remediation with specific plants and agrotechnical treatment achieved a higher yearly decontamination rate compared to natural phytoremediation with native vegetation. It is believed that rhizodegradation is the main mechanism for both phytoremediation approaches.

Summary: Feed intake and digestibility are crucial for animal production, and this study compared the digestibility and intake of grass-only vs. grass-white clover forage in individually housed sheep. Results showed that white clover inclusion increased crude protein concentration and decreased NDF concentration in the offered forage, leading to increased nitrogen intake and decreased NDF intake. Grass-clover swards had greater OM and DM digestibility compared to grass-only swards.

Summary: Modern agriculture heavily depends on agrochemicals to increase crop production, but their indiscriminate use poses detrimental effects on plant growth and soil quality. To address these issues, the usage of plant biostimulants has emerged as an environmentally friendly approach to enhance crop productivity.

Summary: This study investigated the effects of beneficial microorganisms (BMs) on carbon and nitrogen mineralization of organic waste products (OWPs). The results showed that the application of BMs increased carbon mineralization and had varying effects on nitrogen mineralization depending on the type of BM and OWP. The addition of BM reduced the C:N ratio, improved nitrogen availability, and increased microbial activity in the OWP-soil mixture.

Summary: Planting ryegrass in co-contaminated soil can effectively enhance plant growth and removal of co-contaminants, as well as increase the diversity of soil bacteria and alter microbial community composition. The relative abundance of PAHs degrading genera also increased, benefiting the removal of pyrene in the soil.

Summary: The choice of suitable plants is crucial for the successful rehabilitation of metal-contaminated soils. Physiological responses of plants can serve as indicators for the potential toxicity effects of metals. Fertilizers, especially phosphate fertilizers, can improve plant growth and reduce metal-stress.

Summary: This study investigates the application of Effective Microorganisms (EM) as a biological amendment in the rice-crayfish cocropping (RC) model. The findings demonstrate that EM significantly improves the chemical properties of the model and reconstructs a more stable microbial cooccurrence network. The community induced by EM shows positive effects on ecosystem multifunctionality. This study provides strong evidence for understanding the microbiological mechanisms of exogenous biological agents in agricultural ecosystems.

Summary: The present study investigated the relevance of incorporating the longitudinal dimension of within-season multiple measurements of forage perennial ryegrass traits in a reaction-norm model setup. Genetic parameters and accuracy of genomic estimated breeding value predictions were investigated using genomic random regression models. The study found that the additive genetic correlations were higher in later harvests and that modeling the temporal dimension improved the accuracy of breeding value predictions for nutritive quality traits.

Summary: This study aimed to investigate the impact of ryegrass cover crop on soil N2O emissions and denitrifier community size; The presence of plants reduced soil N substrates on one side, while stimulating denitrification with root exudates on the other side; N2O emissions were lower in grass-covered soil compared to bare soil at medium fertilizer levels, and growing grass promoted the proliferation of almost all denitrifying bacteria except nosZ clade II; Ryegrass cover crop has the potential to mitigate soil N2O emissions.

Summary: The continuous decline of earth's natural resources and increased use of hazardous chemical fertilizers are posing great concerns for the future of agriculture. Biofertilizers are gaining importance as a promising alternative to hazardous chemical fertilizers in achieving sustainable agriculture. They play a key role in enhancing crop yield, maintaining soil fertility, and providing essential nutrients in soluble forms for plant growth.

Summary: As the use of digestate in agriculture expands, concerns about its fate in soil also increase. The degradability of organic matter in digestate when applied to soil is still an ongoing topic. A dynamic model was used to simulate the C and N mineralization kinetics during the decomposition of digestates in laboratory incubations lasting 358 days. The model, which includes twelve compartments related to eighteen parameters, provides a detailed understanding of the outcome of exogenous organic matter in soil through the use of accessibility-related variables. The model was calibrated on cattle manure digestate incubation and successfully tested on an energy crop digestate incubation experiment, accurately reproducing the experimental behavior of most variables.

Summary: This study investigated the seasonal effects of coastal embankments on nitrogen storage in Phragmites australis salt marshes. The results showed that the embankment significantly enhanced belowground nitrogen storage and decreased dead aboveground nitrogen storage during both the initial and vigorous stages of plant growth. Furthermore, the embankment increased soil total and labile organic nitrogen during the initial stage and total and recalcitrant organic nitrogen during the vigorous stage of plant growth. However, the embankment had little effect on soil soluble nitrogen and greatly stimulated microbial immobilization and mineralization capacity during the vigorous stage of plant growth.

Summary: The aim of this study was to investigate the impact of effective microorganisms (EM) in biological formulations on the degradation of diflufenican and flurochloridone herbicides. The findings demonstrated that the formulated EMs influenced the degradation of the herbicides, with diflufenican degradation levels reduced and flurochloridone degradation levels increased. The study also calculated the half-life of these substances in laboratory conditions.
