Summary: This study investigates the effects of different arbuscular mycorrhizal fungi (AMF) and NaCl levels on the growth and physiological responses of Gleditsia sinensis Lam., finding that inoculations with Funneliformis mosseae and Corymbiglomus tortuosum significantly improve root dry weight, morphology, and nutrient content. The results suggest that the use of suitable AMF, such as Funneliformis mosseae, may effectively enhance the production of economic tree species in saline soils, optimizing the utilization of these areas.

Summary: Intensive management practices significantly promoted root development, growth, and biomass production in bamboo stands, enhancing root N, P, and K uptake and increasing aboveground biomass. However, these practices had notable negative effects on rhizosphere nutrient pools and biological properties, with potential impacts on soil functioning such as C sequestration and nutrient cycling.

Summary: The study found that under integrated nutrient management (INM) practices, the root length, surface area, and tips of pomelo trees significantly increased, while the root diameter decreased compared to traditional fertilization methods. Additionally, the nutrient content in roots also improved significantly under INM treatments. These results indicate that INM plays a crucial role in root development and nutrient uptake in acidic soil, which can be beneficial for maximizing crop productivity.

Summary: Biochar amendment improves crop growth and nutrient utilization in the soil, specifically in terms of root morphology and nutrient uptake in maize plants. Although biochar has a negative effect on soil phosphorus, it positively affects nitrogen, potassium, and calcium. While biochar lowers nutrient concentrations in shoot tissues, it increases total nutrient uptake and biomass. The use of limited root irrigation methods, such as alternate partial root-zone drying, enhances root-to-shoot ratio.

Summary: Soil drying is a limiting factor for global crop production, but the impact of water uptake across different soils, species, and root phenotypes is not well understood. This study proposes a hydraulic framework to investigate how soil and root hydraulic properties interact in water uptake. The findings show that soil drying leads to a rapid decrease in soil hydraulic conductance, and root phenotypes with low root hydraulic conductance, long roots, and/or long and dense root hairs can postpone soil limitation. This has important implications for crop water use efficiency.

Summary: Aeration is beneficial for hydroponics, but higher aeration intensity does not necessarily lead to linear growth of plants. There is an optimal range of aeration intensity that promotes normal and rapid growth while minimizing energy utilization and operational costs in hydroponic production.

Summary: The use of carbon nanoparticles (CNPs) as a fertilizer synergist can significantly enhance corn growth and nutrient use efficiency by improving the availability of phosphorus and nitrogen in soils. However, the effects of CNPs on plant growth and soil enzyme activity are dose-dependent, with positive effects within a certain range of concentrations.

Summary: Excessive dependence on chemical fertilizers and ignorance to organic and microbial inputs in contemporary agriculture lead to sustainability issues such as degraded soil health and sub-optimal crop productivity. Therefore, integrated nutrient management approaches, such as microbes-mediated integrated plant nutrition, are urgently needed.

Summary: Recycling urban waste products such as human urine, composted household waste, and sewage sludge as fertilizers can reduce the use of NPK fertilizer, improve soil structure, and store carbon. However, there are concerns about the presence of heavy metals, persistent organic pollutants, and plastics in waste products, which may have detrimental effects on soil health.

Summary: Crops with deeper rooting can be achieved through intercropping sugar beet and chicory, which can enhance biomass production, deep root growth, and nutrient uptake. The intercrop showed time-dependent variations in yield advantage and contribution to nutrient uptake from different crops, indicating potential for efficient deep soil exploration and yield advantage compared to sole crops.

Summary: This study proposes using urban gardens to grow vegetables and monitor air quality, and evaluates the safety of consuming food grown in a clean substrate in an urban environment. The results showed that vegetables exposed to higher atmospheric pollution accumulated more trace elements associated with typical urban sources. Washing the food to remove particles on the surface was found to be important. Bioaccessibility testing demonstrated the significance of considering bioaccessibility in risk analyses and its variation depending on the matrix type. Metal concentrations in lettuce were within legal limits for human health protection in Copenhagen.

Summary: The use of cover crops could improve farming systems through nutrient cycling and availability. However, the impact of soil fertility on cover crop performance and nutrient dynamics is not well understood. A two-year field trial was conducted to investigate the effects of different soil fertility levels on the growth and nutrient content of leguminous and non-leguminous cover crops. The results showed that soil fertility level influenced the growth and shoot nutrient content of cover crops, and that legumes produced more biomass than non-legumes at low fertility levels.

Summary: This study investigated the effects of different pretreatments on the phosphorus dynamics of biofertilizers in the soil. The results showed that acidification and alkalization increased the phosphorus solubility of the biomaterials. Acidification significantly increased the total amount of phosphorus released from the biomaterials to the soil, while alkalization increased the apparent recovery in the soil.

Summary: The application of mechanically crushed silicate minerals to agricultural soils can improve crop yields and sequester inorganic carbon. In Denmark, applying glacial rock flour (GRF) to sandy organic fields showed an increase in crop yields in the year of application. The additional ton of GRF applied resulted in a 59 kg/ha increase in maize dry yield and a 90 kg/ha increase in potato tuber yield.

Summary: This study reveals that the liquid scintillation counting method may lead to underestimation of 14C activity and overestimation of soil priming effect. It is found that 33-43% of the studies reviewed used scintillation counting parameters that could underestimate 14C activity. Thus, the accuracy of liquid scintillation counting in measuring soil priming effect should be taken into consideration.

Summary: In organic farming systems, the limited availability of organic waste for application requires the use of alternative nutrient sources to maintain or increase organic food production. This study investigates the ability of various waste-based fertilizers to supply N, K and S to ryegrass, showing that digested manure and manure co-digested with municipal solid waste are effective in promoting plant growth and nutrient uptake. Further research is needed to confirm these findings under field conditions.

Summary: This study used machine learning to investigate the relationship between measured square root of planar root length density (Sqrt_pRLD) at different soil depths and the uptake of isotope tracer (15N) and drought stress indicator (13C) in wheat. The results showed that deep roots at approximately 150 to 170 cm depth were most important for explaining the plant content of 15N and 13C isotopes.

Summary: Green manures are commonly used in paddy fields in China to reduce synthetic fertilizer input and mitigate environmental burden. However, their contributions and mechanisms are not well understood. A network of GM-rice rotation experiments has been established across eight provinces in southern China since 2008, demonstrating that GM with 60% CN can achieve the same rice yield as conventional synthetic N fertilization, while increasing total amino acid concentration, improving CN use efficiency, and reducing C footprint, reactive N loss, and N footprint.
