Vegetables are the most consumed non-staple food globally, and their production is crucial for dietary diversity public health. Use of enhanced-efficiency fertilizers (EEFs) in vegetable could improve yield quality while reducing reactive nitrogen (Nr) losses. However, different management environmental factors has significantly distinctive impacts on effectiveness EEFs. In this study, a worldwide meta-analysis based data collected from 144 studies was performed to assess EEF (nitrification inhibitor [NI] polymer-coated urea [PCU]) application yield, (N) uptake, use efficiency (NUE), Nr losses (nitrous oxide (N2O) emissions, ammonia (NH3) volatilization, nitrate (NO3−) leaching). The effects applied EEFs yields N2O emissions were assessed with practices (cultivation system, type N rate) conditions (climatic soil properties). Compared conventional fertilizers, improved (7.5–8.1 %) (vitamin C increased by 10.7–13.6 %, soluble sugar 9.3–10.9 content reduced 17.2–25.1 %). Meanwhile, demonstrated great potential loss reduction (N2O 40.5 NO3− leaching 45.8 without compromising yield.

Removal Mechanism of Carbendazim in Water by Ozone and Remediation of Carbendazim Pollution in Soil

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: April 23, 2025

ABSTRACT Carbendazim, a commonly used fungicide, was identified as contributor to soil degradation. Despite the extensive use of carbendazim, degradation mechanisms and removal process carbendazim in environment were not yet fully understood. A deeper understanding pathways considered essential for developing effective strategies mitigate long‐term environmental impacts. The using ozone water environments investigated with simulation experiments exposure soil, efficiency also explored under different conditions study. results showed that ozone‐induced proceeded three stages: rapid removal, slow equilibrium. In water, directly reacted generating hydroxyl radicals (˙OH), which oxidized into intermediates, including 2‐aminobenzimidazole, 2‐hydroxybenzimidazole, 2‐benzimidazolone, o‐phenylenediamine. intermediates eventually degraded nontoxic byproducts such carbon dioxide water. treatment enhanced by catalyzing production active substances, (˙OH) hydrogen peroxide (H 2 O ). Increasing aeration frequency four times daily significantly improved reaching peak rate 70.4% after 21 days soil. findings this study clarified theoretical remediation, highlighted critical role process, established scientific foundation remediation targeting carbendazim‐induced contamination.

Agrochemical residues and nitrous oxide (N2O) emissions have caused considerable threats to agricultural soil ecology. Nanoscale zerovalent iron (nZVI) nitrification inhibitors might be complementary each other diminish agrochemical N2O enhance bacterial community diversities. Compared the control, nZVI application declined paclobutrazol by 5.9% but also decreased co-occurrence network node. Combined Dicyandiamide applications significantly emission rates promoted Shannon diversity of community. The increased pH, ammonium nitrogen, Actinobacteriota could promote dissipation. generated double-edged sword effects positively decreasing negatively influencing multifunctionalities. in diminishing promoting diversities simultaneously.
