Summary: The study found that the application of hydrochar has a negative impact on seed germination and plant growth, especially when the application rate exceeds a certain threshold. Different types of hydrochar also have varying effects on plants, and modifying hydrochar can reduce the negative impact on plants.

Summary: Soil plays a primary role in the activity of plant allelochemicals. The phytotoxicity of three natural hydroxycoumarins to different model plant species was compared in this study. Umbelliferone, the most phytotoxic compound, was selected to assess its adsorption and dissipation in two distinct soils. The results showed that soil processes can reduce the allelopathic activity of hydroxycoumarins, and the bioactivity of hydroxycoumarins may be better expressed in certain scenarios.

Summary: This paper is the first meta-analysis that examines the effects of microplastics on plant and soil health in the plant-soil system. The study finds that the composition of polymers in microplastics can impact plant morphology, antioxidant production and photosynthesis capacity. Different agricultural plants also show varying sensitivity to microplastics. Microplastic-impacted soils tend to be more porous and retain more water, but this does not improve soil stability or increase soil microbial diversity.

Summary: The study investigated the adsorption, dissipation, and phytotoxicity of the chiral monoterpene pulegone in different soils to various plant species. Results showed that the phytotoxicity of pulegone varied among plant species, with S-pulegone exhibiting higher toxicity compared to R-pulegone.

Summary: This study investigated the effects of polyethylene MPs (PEMPs) and polylactic acid MPs (PLAMPs) on the physio-biochemical performance and metabolomic profile of soybean, as well as the bacterial communities in soil. The results showed that PEMPs had no toxicity on the plant growth, while 0.1% PLAMPs significantly reduced root length. MPs in plant leaves affected peroxidase (POD) and catalase (CAT) activities. Metabolomics study indicated that amino acid metabolism was the significantly affected pathway. Additionally, only 0.1% PLAMPs altered the bacterial communities in the rhizosphere soil.

Summary: Copper-based nanoparticles are widely used in agriculture for their diverse properties, but long-term excessive usage may pose risks to soil systems. Their antimicrobial effects can impact soil microbes, highlighting the need for further research on their potential impacts on the soil-plant environment. Further studies are needed to understand their interactions with soil components and factors influencing their behavior in agricultural settings.

Summary: Leucaena leucocephala is an invasive alien species with allelopathic properties, possibly due to the release of allelochemicals such as mimosine. However, the concentrations of these chemicals in the vicinity of L. leucocephala have not been reported.

Summary: The combination of different amendment materials has been investigated for its potential to alleviate salt stress in saline-alkali soil. The study found that the combination of 2.0% phosphogypsum, 2.0% humic acid, 0.25% bentonite, and 0.03% sodium carboxymethyl cellulose (T6) showed the most significant improvement in physicochemical and biological properties of the soil, as well as promoting the growth of oilseed rape. The amendments were found to alleviate salt stress in the plants by activating anti-oxidative enzymes and osmoregulatory substances. This research provides valuable insights for the combined application of different amendment materials in soil reclamation.

Summary: This study aimed to determine the effects of biochar on fumigant emissions, distribution and persistence in soil, nematode control, and potential toxicity to plants. The results showed that biochar treatments significantly reduced fumigant emissions, and the reduction was correlated with biochar's adsorption capacity. The residual fumigant concentrations in soil were negatively correlated with cucumber germination rate and dry biomass.

Summary: This paper examines the impacts of microplastics on terrestrial plants, focusing on the adsorption and accumulation of microplastics in plant seeds and roots, as well as its effects on plant growth and metabolism. The study finds that the phytotoxicity of microplastics depends on their properties, plant tolerance, and exposure conditions. The accumulation of microplastics may also affect crop productivity, food safety, and quality, posing potential health risks.

Summary: Intercropping of 'LingwuChangzao' jujube with Gramineae herbage has shown significant improvements in land equivalent ratio, fruit quality, and soil properties. However, some nutritional quality indicators of forage were lower compared to monoculture. Additionally, intercropping systems had significant effects on soil organic carbon fractions and C-N cycling enzyme activities.

Summary: One-third of global annual food production is wasted, but this waste can be turned into valuable industrial products. Converting food waste into soil amendments is an effective approach to recover nutrients and reuse waste. Applying these amendments to soil can improve its fertility, increase crop production, and reduce contaminants, but the efficiency depends on various factors. Engineered biochar/biochar composite materials made from food waste are promising for soil remediation and improving nutrient use efficiency. Quality standards, policies, and regulations in the food supply chain are necessary to manage food waste.
