Summary: The study investigated the adsorption, desorption, and dissipation of MC-LR and MC-RR in agricultural soils. Results showed that soil pH and clay influenced the adsorption and desorption of MC-LR, while organic matter and cation exchange capacity played a key role in the fates of MC-RR. The dissipation half-lives of MCs were shorter in sterile soils, indicating the significant role of abiotic degradation in reducing MC concentrations.

Summary: In this study, a magnetic NH2-MIL-101(Al)/chitosan nanocomposite (MIL/Cs@Fe3O4 NCs) was synthesized and successfully used for the removal of azithromycin (AZT) from aqueous solutions. The synthesized nanocomposite was characterized using various techniques, and the optimization of key factors in the AZT adsorption process was carried out using response surface methodology. The results showed that the optimized conditions led to high removal efficiency and adsorption capacity of AZT. The thermodynamic and kinetic analysis indicated that the adsorption process was spontaneous and endothermic in nature. The reuse of the nanocomposite and its performance under real conditions were also evaluated.

Summary: This paper summarizes the influences of minerals and organic matter on the adsorption, degradation, and plant uptake of sulfonamides (SAs) in soil. Minerals effectively adsorb SAs through mechanisms such as cation exchange, complexation, hydrogen bonding, and cation bridging, while soil organic matter significantly increases their adsorption. Soil organic matter reduces the mobility of SAs in the environment, while dissolved organic matter increases their availability.

Summary: The review focuses on the removal techniques of Levofloxacin from wastewater, particularly on adsorption and photocatalytic degradation methods. It is found that photocatalytic degradation is the most effective method, but the toxicity of degradation products needs further monitoring. Biological degradation may be the most environmentally friendly method, but research in this area is limited. The review suggests the potential of hybrid techniques to improve the efficiency of Levofloxacin removal.

Summary: In wetland environments, the response mechanism of plants to environmental stresses is significantly influenced by factors such as water level, water-level amplitude, and duration, affecting the ratios of nutrients such as nitrogen and potassium. Plant N:P and N:K ratios indicate significant phosphorus and potassium limitations, and nutrient trade-offs help to mitigate the negative effects of hydrological fluctuations on plant nutrients and their ratios.

Summary: Thirteen states agreed to share their soil test based P and K rate recommendations for nine major crops, with the aim of comparing fertilizer recommendations, rationalizing similar recommendations across state lines, and examining challenges to developing a cooperative regional approach to P and K recommendations. Differences in fertilizer recommendation philosophies among states were found to be the main reason behind discrepancies, leading to important recommendation differences due to different philosophies, numerical presentations, and extraction procedures. Despite widespread adoption of the Mehlich-3 extraction procedure, variation in fertilizer P and K rate recommendations among states has not been reduced, highlighting the need to examine and standardize the soil testing and recommendation process.

Summary: Cultivation of marshes to arable land or sugarcane causes depletion of soil organic carbon within a short time. This study investigated the molecular composition of soil organic matter and found that land use change significantly altered it. The decrease in lignin and phenolic compounds during land use change was consistent with the decrease in soil organic carbon, indicating their instability. Land use change also resulted in more diverse molecular components in arable land or sugarcane compared to marshes. The findings suggest that land use change not only affects carbon fluxes but also changes the molecular mechanisms driving the carbon cycle.

Summary: The study investigated a novel multifunctional biochar for treating nutrients, oil, and harmful algae in water. The results showed that Mg-impregnated biochar had a high adsorption capacity for phosphate, while RL-modified biochar significantly reduced TPH, especially aromatic and light aliphatic fractions. Mg-RL-biochar had the strongest inhibition effect on algae in water without contaminants, with a biomass reduction of 61-64%. Overall, Mg-RL-biochar was suggested as an ideal choice for removing phosphate and TPH, and inhibiting the growth of toxic algae.
