Introduction: Composting is one of the effective environmental protection and sustainable measures for improving soil quality and increasing crop yield. However, due to the special physical and chemical properties of saline-sodic soil and the complex rhizosphere microecological environment, the potential mechanism of regulating plant growth after applying compost in saline-sodic soil remains elusive.

Methods: Here, we investigated the effects of different compost addition rates (0, 5, 15, 25%) on plant growth traits, soil chemical properties, and rhizosphere bacterial community structure.

Article Synopsis
  • Soil salinization poses a significant threat to agriculture, but compost application can help reclaim saline-sodic soils by enhancing soil properties and plant health.
  • Compost significantly boosts soil nutrients and enzyme activities, leading to improved leaf photosynthesis and ion balance in alfalfa plants.
  • The study also found that compost alters rhizosphere fungal communities by decreasing pathogenic fungi and changing community diversity, highlighting its potential for improving plant resilience against saline stress.

Article Synopsis
  • - The research investigates how applying phosphogypsum and rice cultivation (PRC) affects soil properties and bacterial communities in saline-alkali paddy fields in Songnen Plain, China, which is crucial for food security and agricultural advancement.
  • - Results indicate that PRC significantly improves soil conditions by reducing salinity, enhancing nutrient efficiency, and increasing enzyme activity related to carbon and nutrient cycling.
  • - The study finds that after years of PRC application, soil quality continues to enhance, suggesting a sustainable approach to managing saline-alkali land that boosts agricultural productivity and ecosystem health.

Article Synopsis
  • The study explores how a specific metal-organic framework (UiO-66(Zr)-AO) made from carbohydrate can effectively remove uranium (U(VI)) from the environment, demonstrating its potential for real-world application in environmental cleanup.
  • Experimental results indicate that UiO-66(Zr)-AO has a rapid removal rate, high capacity for U(VI) uptake, and retains efficiency after multiple uses, making it a strong candidate for uranium extraction.
  • The mechanism of removal involves different interactions based on pH levels, with detailed analyses confirming that the framework can bind to uranium ions effectively, highlighting its significance for uranium recycling and environmental protection.

There is limited information on the phosphorus availability under copper and tetracycline-amended composting: Insights into microbial communities and genes. Thus, this work investigated the phosphorus redistribution and transformation, illustrated the variation in microbial communities and genes, and ascertained the multiple action-patterns among which within copper and tetracycline-amended composting. Phosphorus bioavailability reduced by 8.

In Northwestern China, more and more traditional cultivation system (TC) with no mulching and flood irrigation have been replaced by modern cultivation technology (MC) combining plastic film mulching with drip irrigation. Does plastic film mulching increase or reduce soil CO emission in arid areas? In order to study the effects of plastic mulching on soil CO efflux, a field study was conducted to compare soil CO concentration, soil CO efflux, soil temperature and moisture between the TC treatment and the MC treatment during a cotton growing season in Northwestern China. The seasonal patterns of soil profile temperature and soil moisture in the TC treatment were similar to that in the MC treatment.

Various environmental stresses strongly influence plant development. Among these stresses is drought, which is a serious threat that can reduce agricultural productivity and obstruct plant growth. Although the mechanism of plants in response to drought has been studied extensively, the adaptive strategies of () Yü et Lu grown in drought and rewatered habitats remain undefined.
