Summary: This study investigated the effects of chitin amendments on the soil health and plant growth in continuous cropping of soybean. The results showed that chitin amendments, especially crude chitin, significantly improved soil pH, nutrient content, and microbial activities. These amendments also suppressed potential plant pathogens and promoted the growth of soybean plants. The mechanisms behind these effects were found to be mediated by soil pH, soil microbial activities, and potentially beneficial microbes.

Summary: The study revealed that high boron doses promoted boron accumulation in soil, leading to harmful concentrations that impacted soil biodiversity. There was a close interaction between boron and organic labile fractions, increasing boron availability in soil solution. Organic amendment did not enhance boron soil adsorption, but facilitated boron plant uptake, and the highest boron dose had a detrimental impact on plant physiology, eventually causing lethal effects on the plants.

Summary: This study investigated the effects of deficit irrigation and soil organic amendments on soil microbial communities and tomato yield. The results showed that deficit irrigation had a strong impact on the bacterial and archaeal community composition, but 75% deficit irrigation did not significantly affect microbial communities or biomass. Soil organic amendments did not stabilize the compositional shifts induced by deficit irrigation, but their recalcitrant carbon had residual effects on microbial communities. Soil moisture was correlated with microbial metabolic potentials, enhancing the residence time of organic amendments in deficit irrigation soils.

Summary: Organic matter amendment is used to improve soil quality in agricultural and urban settings, including supporting local food production and reclaiming disturbed soils in urban regions. Compost and biochar had the greatest improvement on soil organic matter content, while biosolids had greater nutrient benefits. The application of organic matter amendments also improved chemical and physical soil quality parameters. However, there are still gaps in the literature regarding the effects of amendments in urban gardens, soil depth greater than 30 cm, and the persistence of soil organic matter.

Summary: The study found that water-soluble anionic polychloramide biocides were less affected by soil interference compared to cationic polymeric biocides. Certain soil components, such as polyacrylic acid and cellulose nanocrystals, inhibited the cationic biocides but had little impact on the anionic polychloramide. Glycine and bovine serum albumin reduced the biocidal activity of both anionic and cationic polychloramides by extracting oxidative chlorine, while succinimide increased bacteria deactivation by extracting oxidative chlorine from the polychloramides and transporting it to the bacteria.

Summary: Intensive cultivation and nitrogen fertilization in croplands of southern China lead to soil acidification, which can be mitigated by the application of soil amendments. In this study, lime, organic manure, and straw biochar, alone or in combination, were used to treat severely acidified field plots. The application of organic materials with lime significantly influenced the rhizosphere microbial communities, plant disease resistance, and plant physiological parameters. The optimization of bacterial community composition in the rhizosphere played a key role in enhancing plant disease resistance.

Summary: Soil organic amendments can alter microbial communities and their resilience to environmental stresses, impacting carbon and nitrogen transformation. This research investigates the impact of temperature change rates as a microbial stressor and evaluates the potential use of organic amendments in steering soil ecological response. The results indicate that organic amendments can mitigate the sensitivity of soil to temperature changes.

Summary: Bark-derived soil amendments can influence the gene copy numbers and community composition of fungi and bacteria, potentially increasing microbes and promoting soil and plant health processes. The carbon content in agricultural soils has been declining globally, but amendments with forest industry side-streams can counteract this trend. In a 10-month microcosm study simulating seasonal temperature changes, industrial conifer bark and its cascade process materials were found to have effects on the soil microbiome under barley cultivation in clay and silt soils. The type of amendment, soil type, and simulated season all influenced the bacterial and fungal community composition, with certain amendments increasing specific microbial groups.

Summary: This study evaluated the degradation rate and risks to the environment and human health posed by four commonly used pesticides in Australian urban landscape soils. The results showed that the properties of the pesticides were related to the characteristics of the soils and could potentially affect non-target organisms and food safety. The study also highlighted the need for reducing risks to human and environmental health.

Summary: Potato is a major tuber crop that faces significant post-harvest losses every year due to its perishable nature. This study investigates post-harvest losses in potatoes during various stages, including farm operations, handling, packaging, storage, and at the wholesaler/retailer/household level. The findings suggest that weight/moisture loss during storage is the highest form of loss, and storing potatoes at 10-12 degrees C with sprout suppressant is preferable.

Summary: Livestock overgrazing poses a threat to plant and soil microbial diversity. This study examined the relationship between plant and soil microbial diversity in ungrazed and overgrazed grasslands in northern China. The results showed a positive correlation between plant and microbial diversity in ungrazed grasslands, which remained unchanged in overgrazed grasslands. Furthermore, different mechanisms underlay the correlations between plant and microbial diversity in the two conditions.

Summary: Soil phosphatase is inhibited under arsenic stress, with greater inhibition observed in acid soils compared to alkaline soils. The inhibition mechanism includes competitive inhibition, linear mixed inhibition, non-competitive inhibition, and anti-competitive inhibition. The ecological dose (ED10) for arsenic ranged from 0.11 to 164.07 mg/kg depending on soil type. The V-max/K-m of phosphatase is a more sensitive index for assessing arsenic contamination, and soil pH and cation exchange capacity are important factors affecting arsenic inhibition on soil phosphatase. Adjusting the assay buffer pH to the soil pH is crucial for accurate evaluation of arsenic toxicity.

Summary: Microbial inoculants have gained attention as an eco-friendly solution for improving agriculture productivity worldwide. However, the inconsistent impacts of these inoculants can be attributed to limited knowledge of their mechanisms on crop growth and their ecological characteristics. Evaluating the ability of inoculants to colonize new habitats is believed to be an important step in enhancing their consistency and efficiency. In this study, the impact of three microbial inoculants on wheat growth under drought conditions was investigated, and colonization by Bacillus paralicheniformis and Bacillus subtilis was found to be crucial for promoting crop growth.
